How Do I Drain My Rv Septic Tank? (Solved)

Hook up one end of your sewage drain hose to the black tank valve on your RV. Secure the other end of the hose to the valve at the sewer line or dumping station. Pull the valve to empty the black tank, allowing it to drain completely. Flush the black tank with water to clean it.

How often do you empty a septic tank in RV?

In simple terms, if you have lots of people on board, you might need to empty the tank daily. But if you are just traveling alone or maybe with one more person, your tank would need emptying less frequently – maybe even once a week. The rule of thumb is to empty the tank before it fills up.

How much does it cost to empty an RV septic tank?

Dumping your black water tank can cost anywhere from Free to $35. Some public campgrounds, waste water treatment plants, rest stops and RV stores will allow free dumping. Private business and campgrounds will charge between $10 -$35 with an average of $20 for dumping the tanks.

Can I dump my black tank at home?

In most cases, it is legal to dump both your RV black and gray water tanks into an approved residential sewer system. There may be local ordinances and restrictions, and you should check them. However, the black and gray water from your RV is essentially the same as what comes from your toilets and sinks at home.

How do you get rid of the poop pyramid in RV black?

To eliminate a poop pyramid, you need to get water into your black tank. The first thing you should do is close the black tank valve and get as much water into the black tank as possible. If the poop pyramid prohibits you from putting water into the tank, get some tank cleaner to pour down into the sewer drain.

How do I empty my septic tank?

A local septic tank emptying company will send out one of their tankers with a long flexible hose. The tanker operator will insert this into your septic tank and a powerful suction force is then used to empty all the waste out.

Where can I empty my RV sewer?

5 Places to Dump Your RV Black Water

  • Campgrounds and RV Parks. The easiest place to dump and clean your RV black water tank is at a full hookup campsite.
  • Gas Stations.
  • Rest Stops / Rest Areas.
  • RV Dealerships.
  • An Approved Municipal Sewer System or Septic Tank.

What is gray and black water in RV?

A gray water tank collects water that goes down the drain of your shower and sinks. The black water tank holds the wastewater from your toilet. Though it may seem easy to do, you can’t just empty your tanks and be on your merry way.

How do I drain my RV black water tank?

To dump your RV’s black water holding tank:

  1. Connect a high-quality, reliable sewer hose to the outlet drain of your RV’s sewer system.
  2. Pull the black water valve and let the tank drain completely.

Can you dump RV grey water on the ground?

Generally, as long as your gray tank contains water that was used for washing, it’s legal to dump it on the ground.

How to Empty your RV Holding Tank

The vast majority of travel trailers, fifth wheels, and RVs are equipped with onboard storage tanks of various sizes. These tanks collect the water from the sinks and showers, as well as the sewage waste from the toilets (s). The grey water tank and the black water tank are the names given to these two tanks. In most cases, the combined volume of the two holding tanks is approximately the same as the entire capacity of the freshwater reservoir. The grey represents approximately 60% of the total quantity, with the black representing 40%.

When these tanks grow full, they must be emptied on a regular basis.

This applies to both holding tanks and greywater, which must be disposed of in the same manner as the blackwater.

How to Dump Your Tanks

Please don’t make this any more complicated than it already is. Before you begin, double-check that you have the appropriate RV sewer hoses and accessories. Let’s have a look at the steps involved in emptying the tanks at a designated RV disposal site.

Step 1

Install the sewage drain hose, being sure to double-check that all of the fittings are securely fastened.

Step 2

Open the gate valve on the black tank. That’s the “T” handle that’s located on one of the sides of the unit where the discharge pipe is significantly bigger. To avoid confusion, always keep in mind that the black tank must be drained first, and ideally while there is grey water present in the grey tank. Many RVs have a black tank that drains better when they are closer to full rather than when they are just partly full. The increased volume has the effect of increasing the pressure as it left the tank, which aids in the better evacuation of the tank.

However, a large portion of your dumping requirements will be decided by your unique application.

Step 3

Once the black tank has been entirely emptied, it is preferable to flush the tank with fresh water if at all feasible. This cleans the tank walls and washes away material that may have accumulated in the corners of the tank due to poor drain turbulence. A hose from a water supply tap can be connected to the appropriate input port on your RV’s tank cleansing system if it is equipped with this feature. If your device does not have a built-in flushing circuit, you can install a simple “Back Flush” rinse adaptor to make up for this shortcoming.

  1. This may be used not just to flush the black tank, but it will also perform wonders for cleaning the grey tank as well.
  2. The tank level sensor can only function properly if the tank walls are substantially free of debris.
  3. The Flush King is comprised of a separate 3′′ gate valve and a 45-degree clear elbow with a standard hose input port, as well as a separate 3′′ gate valve.
  4. If you see clear, non-opaque water pouring out of the drain pipe, this means that the tanks need to be flushed.

In this case, if your RV is equipped with internal tank flushing, I strongly advise you to get a clear plastic elbow so that you can see the status of the draining water while you are driving.

Step 4

After you have completed the process of emptying and flushing the black tank, you must now evacuate the grey water. Having closed the black tank valve, open the drain gate valve on the grey water tank. The grey water is regulated by a gate valve located at the smaller discharge pipe system. The sewage from each of them flows into the huge 3′′ output sewage pipe, no matter which direction it goes. Cleaning the huge 3′′ sewage hose of harsh waste and related odors is made easier by emptying the grey water last, as well as by draining the tank after each use.

Even after emptying your tanks, there can be times when you will not be able to flush even the black tank, such as if you are at a rustic basic dump site that does not have access to fresh water for flushing reasons.

Setup at a Full-Service Campsite

The next section will discuss the setup when you are connected to a fully maintained site.

Step 1

The black valve should be in the closed position, and the grey valve should be in the open position. Just as at home, this will enable for quick drainage of the shower and the sink water.

Step 2

It is just necessary to keep an eye on the black. It is recommended that the grey water valve be closed when the black water tank is about three-quarters full.

Step 3

All that is required is that the black be kept under surveillance. It is recommended that the grey water valve be closed when the black water tank is around three-quarters full.

Step 4:

Once everything has been flushed, the black may be closed and the grey can be opened once more. The hose will be washed once more by the grey water drainage system. What if your black tank has never been completely cleaned out and the level sensor is no longer functional, or is only intermittently operating properly? So, here are some recommendations for cleaning with a heavy hand.

Additional Tips

Normally, I would recommend completely emptying your holding tanks before hitting the road for a road trip or vacation. This contributes to the reduction of the vehicle’s weight, which in turn improves fuel efficiency. This approach, on the other hand, necessitates the use of a black tank that is at least half filled. Prepare to take the road with at least a half-full black sewage tank in your vehicle. Purchase two or three bags of ice and place them directly into the RV toilet, making sure that they are completely flushed down into the holding tank.

  1. A mechanical cleaning will occur as a result of the floating ice in the holding tank, which will scour the walls and remove any build-up that may have developed over time.
  2. Once flushed into the holding tank, this assists in the removal of buildup as well as the maintenance of a clean tank and the creation of a less adherent surface for the development of bacteria.
  3. Macerators are now standard as an option on many popular RVs, and they are becoming increasingly popular.
  4. So, what precisely are the primary benefits of having this feature?
  5. First and foremost, you have the option of emptying your black tank, as well as your grey tank, in a domestic toilet, provided that it is within reach of the discharge line.
  6. It pushes it and has the ability to propel its output above its own altitude.
  7. Because I have personally used this product, I can attest to the validity of many of the manufacturer’s claims.
  8. Naturally, there is more to RV toilets than simply altering the holding tank’s capacity.

Instructions on How to Empty Your RV Holding Tanks

A variety of germs and bacteria may be found in sewage and can be dangerous if consumed or kept on exposed skin for an extended length of time. Always exercise extreme caution when coming into touch with the effluent or waste water. Any exposed area, such as hands, clothing, shoes, feet, tools, doors and locks, and so on, should be completely cleaned before using them again. Nothing is more frustrating than not cleaning up after yourself and polluting your steering wheel as well. It’s important to remember that everyone’s reaction to contamination is different.

Sickness may spoil an otherwise enjoyable RVing trip.


Make sure you have all of the necessary tools on hand.

  • Disposable gloves for handling the sewage line
  • Rinse hose for your black water flush
  • Bleach wipes for sanitizing
  • And other supplies. Check the clear sewer adapter to see whether your tanks have been completely emptied
  • Sewage extension hose, with a minimum of 30 feet recommended
  • Couplers with a 90-degree bayonet fitting, a 45-degree fitting, or a straight fitting
  • Following the event, hand sanitizer should be used.

Storing your hoses/tools:

It is always best to keep hoses and connections in an enclosed, separated area in order to avoid interaction with other goods and cross-contamination. It is recommended that you immerse all of these instruments in a bleach solution (1/4 cup per gallon of water) for at least 4 hours at the start of each season to sterilize them. This is also an excellent opportunity to inspect and test the hose for leaks, and if necessary, replace the line. Because it might become brittle and damaged, the average hose life is between 2-4 years.

When to Dump:

Tanks that are not at least two-thirds full should not be dumped. If you have to dump, fill the tanks with water until they are at least two-thirds full before starting. This will assist in promoting the suspension of all solids and particles in the water and the movement of the water out of the tank. In the event that you want to travel before dumping, you might add some dish washing detergent (1/4 cup to a tank) and let it to splash about before dumping. Extreme caution should be exercised when using too much soap.

Steps to dump your gray water and black water holding tanks:

Begin by pulling up to the RV dump station and aligning the black holding tank drain valve with the dump station’s opening as closely as feasible, if possible. The disposal location will be kept safe in the event of an accident because of this precautionary measure taken. If your RV has more than one place for your drain valves, always drain the black tank first if there are many locations. Unlock any compartments on the RV that you will need to get to in order to dump the tanks later.

Step 2:

Obtain the sewer hose and put on latex or other disposable gloves (in order to avoid any contamination). To begin, make sure that both the gray and black water valves are completely closed before removing the cover from the holding tank draining opening.

Step 3:

First and foremost, connect the hose to the disposal station hole. It is recommended that you use an elbow and a hose ring to connect the sewage hose to the dump station hole, as this will keep the line in place and prevent any splatter from occurring. If the ring or the elbow are not readily available, put the end of the sewage hose into the dump station’s hole, which should be approximately eight to twelve inches in diameter and eight to twelve inches deep (if you only insert the hose a few inches the hose may come out when dumping the tanks and that will cause a large mess).

Many websites recommend that you start with Step 3 and then move on to Step 4. We recommend that you start with Step 3 to avoid any inadvertent spilling. Sponsored Links are links that have been paid for by a company.

Step 4:

Preparing to connect the sewage hose to the holding tank drain outlet requires checking to make sure it is properly fastened to the adapter before attaching it. Remove the cap first, with the sewer hose positioned beneath to catch any drops (open end up). Once any leaks have ceased, join the sewer line to the adaptor, making sure it is securely fastened. A partly connected hose is more frequent than one may imagine, so make sure the tabs on the adapter are precisely aligned with the stubs on the tank drain before proceeding.

Step 5:

Pulling out the black water tank valve first, after making sure everything is secure, is a good idea. Your ears will pick up the sound of effluent streaming through the hose, slowing down, and eventually becoming a trickling sound.

Step 6:

You should connect a dedicated garden hose to the RV’s black tank rinse system if one is installed permanently. This will allow you to connect it to both the RV’s and the dump station’s water supplies at the same time. Never use fresh water for the black tank rinse, and don’t turn on the water until step 5 has been done completely. (Alternatively, a portable flushing wand can be used for this stage.)

Step 7:

As a result, some sediments may have accumulated in the bottom of the tank as well as on the tank sidewall, and it is now necessary to do a black tank flush to assist in cleaning out the tank. You can run water through a black tank rinse that you connected in step 6 for two to five minutes, then turn off the water and disconnect the garden hose to assist remove any sediments that may have remained. Close the black water tank drain valve by pulling the handle all the way down until it is completely closed.

In order to replicate the function of the black tank rinse system, ask your companion to flush the toilet.

If there is a long line at the trash station, please be kind to others waiting in line.

Step 8:

Open the gray tank valve at this point. As in step 5, you’ll hear water flowing, then slowing down and eventually stopping. Close the valve on the gray water tank. If you have more than one gray tank, you will need to repeat this procedure.

Step 9:

You’re nearly through with this section. To flush and rinse the tanks one more time, fill the tanks with water until they are two-thirds full (if you do not have a gray tank rinse system) and continue the emptying process until the tanks are clean. If there are other people waiting to use the disposal station, please be considerate and skip this section. It is not recommended to use non-potable rinse water in your fresh water system for this purpose since it will pollute the system and need total sanitation.

Step 10:

Check to make sure that both your black and gray water tank valves are closed, and then disconnect the sewage hose from the RV’s tank outlet to prevent backups.

Step 11:

Lift the end of the sewage hose (the end that has just been detached) to allow the hose to completely drain into the dump station. If you have access to a non-potable water hose, you can run water through the sewage hose to clean it out. Remove the sewage line from the hole in the dump station and thoroughly clean the exterior of the hose with water. Using a hose, rinse the area surrounding the hole to verify that any leakage has been cleaned up before covering the dump station hole. Replace the drain cap on your RV.

Step 12:

The sewage hose’s end (the end that was just detached) should be raised in order to allow the hose to completely drain into the dump station. If you have access to a non-potable water hose, you can run water through the sewage hose to clean it. The sewage hose should be removed and rinsed thoroughly on the exterior of the hole in the disposal station. Make sure any spillage has been cleaned up in the area surrounding the hole and then cover the dump station hole with a tarp. Replace the RV drain cap if it has been removed accidentally.

Step 13:

Latex gloves should be disposed of in a garbage bin (not at the dump station) or placed in your RV’s rubbish bin, whichever is appropriate. Bleach wipes should be used to clean any surfaces that were touched while wearing the gloves. In case the gloves spilled, you should wash or sterilize your hands immediately.

Step 14:

As soon as there is a backlog, move the rig to make room for the next user to use the dump station, and then check the holding tanks display panel. This is an early warning indicator that the sensors may be clogged and should be cleaned out immediately. Look no farther than the ice cube method in the section below for a cheap and ecologically friendly solution to this problem.

Step 15:

It is necessary to move the rig in order to allow the next user to utilize the dump station, and then to inspect the holding tanks display panel. If they do not read empty, this is a warning indicator that the sensors may be clogged with debris. An cheap and ecologically friendly solution to this problem can be found in the ice cube method described below.

Step 16:

Make a note of any additional information or updated information about the RV dump station that you would like to share with other RVers via

Step 17:

The chore of emptying the holding tanks in your RV has now been completed.

Step 18:

Please submit the updated or validation information to as soon as you have access to the internet.

Step 19:

Take pleasure in your RV travels.

The ice cube trick:

If, during Step 14, you discover that the holding tanks’ display screen does not indicate that they are completely empty, flush many (6-8) large bags of ice cubes down the toilet and into the holding tank. Leaving ice cubes in the tank will assist in cleaning your sensors, and the ice will have completely melted by the time you reach the nearest trash station. As soon as you reach at the next dump site, fill the tanks with water before emptying them.

This will help to suspend the sediments that have splashed against the sides of the tanks throughout the transportation process. It’s possible that you’ll have to repeat this procedure. This is a way of cleaning your holding tanks that is healthy to the environment.

Disappearing RV Dump Stations:

It appears that recreational vehicle dump stations, sanitation stations, and dump points are being phased out, and in many cases, this is due to the high cost of managing a dump station, as well as the inability of RVers to utilize an RV dump station in an environmentally acceptable manner. Please exercise caution and seek assistance if you are unsure of what to do at the RV dump station. Proper dumping techniques may be learned with the assistance of a trained professional. RV Lifestyle Seminars, also known as RV Life On Wheels Conferences, are a terrific opportunity to learn more about recreational vehicles (RVs) and meet other RVers.

Recreational Vehicle Dumping Etiquette:

  • Don’t dump anything else into the dump station than the contents of your holding tanks. Please do not dump directly onto the apron of the disposal facility! Please be nice and pick up after yourself if you create a mess or spill something. Please do not leave any additional rubbish in the vicinity. Keep old rubber gloves out of the sewage and away from the water supply. They are not biodegradable in any way. Don’t leave it to the next person to deal with

Keep in mind that dump stations are being closed as a result of misuse! Submit a report of abuse.

Easy steps to help dump stations stay open:

It is critical that all RVers learn to play their part in ensuring that RV dump stations remain open and operating for the benefit of RVers worldwide in the future. We can take the following five simple steps:

  1. Ensure that there is sufficient water in the black water holding tank (enough water to completely cover the solids)
  2. Use of formaldehyde-based compounds is prohibited. Do not exceed the required amount of holding tank chemicals for the size of holding tank you have (more is not always better)
  3. Every time you use a disposal station, make an effort to maintain the area clean (see out steps above). Leave the dump station location in the same manner in which you would like to arrive at one. Keep your holding tanks out of the environment unless they are at permitted dump stations.

A Beginner’s Guide To RV Holding Tanks

Liz Wilcox contributed to this article. RVing may take you to some breathtaking destinations and provide you with the opportunity to make lifelong memories. However, not every aspect of RVing is visually appealing. It’s an unglamorous — but vital — aspect of any RV excursion to keep up with and empty your septic system on a regular basis. And if this system is not properly maintained and cared for, things may get rather unpleasant. Whether you’re a first-time RV owner or you’re planning to rent an RV via Campanda, it’s crucial to understand how to properly maintain your RV tanks.

What does an RV septic system look like?

Recreational vehicles are often equipped with three tanks, which are positioned on the underneath of the vehicle to ensure that everything runs properly.

1. Fresh Water Tank

An RV typically has three tanks: one for fresh water, one for gray water, and one for black water. This tank is used to store fresh water, as the name implies. This is the water that comes out of your faucets and showers.

2. Grey Water Tank

The grey tank is responsible for storing the waste water from your RV shower and kitchen sink. It is possible that some secondhand campers and older RVs may not have this tank.

3. Black Water Tank

For novice RVers, this is the one that gives them the creeps.

The black tank is responsible for storing waste water from the toilet. This tank is used to collect all filthy water if your RV does not have its own separate gray tank. Any one of these tanks, if not properly maintained, might pose difficulties for the owner.

How often should I empty my RV tanks?

There is no hard and fast rule when it comes to how often you should empty your tanks; it all depends on how frequently you use them. The frequency with which you should empty your tanks is a matter of personal preference. If you are traveling with a large group of people, it is possible that you may need to empty your tanks every two days. If you and your spouse are the only ones in the house, once a week may be plenty. As a general rule of thumb, you should wait until your tanks are approximately two-thirds full before empties them.

Some recreational vehicles are equipped with devices that allow you to see exactly how much fuel is left in your tanks.

This type of sensor begins to malfunction after a few years of use.

Keeping track of how much water waste you generate is critical to staying on top of the situation.

How do I empty my RV tanks?

When it comes to emptying your tanks, there is no hard and fast rule; it all depends on how much you use them. Your tank’s capacity is determined by how often you use it. The requirement to empty your tanks every other day can be necessary if you are traveling with a large group of people. Depending on how many people are in the household, once a week may be plenty. After your tanks are around two-thirds full, it’s a good idea to wait until they’re completely empty. There is significantly better flow during dumping, which results in a lot more efficient overall procedure.

But, be careful, this is an excellent technique to determine when to dump.

When paper or other trash gets stuck to the sensor, even fresh ones might produce an inaccurate reading, causing it to read “full” when it is not.

How do I maintain my RV septic system?

Starter kits like this one are available at places like Walmart and RV retailers. Once you’ve gotten the hang of emptying the tanks in your recreational vehicle, the task can be completed fast and efficiently. However, there is more to properly operating your tanks than simply emptying them – upkeep is just as vital and will help you avoid problems down the road if done correctly. In general, flushing your system on a regular basis, as well as cleaning and sanitizing your tanks, will keep your system up and running relatively trouble-free.

Other things to know about your RV holding tanks:

The fresh water tank, however it is the least frightening of the three tanks, nonetheless need care from time to time. When connected to water or filling the tank, only use a potable water hose to avoid contaminating the water. Because of their white tone, they are simple to distinguish. When using this tank, it is critical to pay close attention to the weather. Insulate your hose during freezing weather and drain your fresh water during periods of excessive heat to avoid water stagnation and evaporation.

The fresh water tank is responsible for storing the water that flows out of your faucets. It’s the least frightening of all of the RV holding tanks. If the tank begins to smell, it is possible that it has become polluted. To clean the tank, use regular household bleach.

  1. Pour 14 cup of bleach into your tank for every 15 gallons of water it holds. Continually run the water until you detect the fragrance of bleach Continue to run the machine until all of the bleached water has been removed. Allowing your tank to rest for 24 hours is recommended. Ensure that your tank is fully refilled and that the water is running until the bleach smell is gone. Use as you normally would

Gray Water Tank

Once again, here is the location where the water from your sink or RV shower is collected. Large travel trailers and fifth wheels may have two gray tanks to accommodate the additional space. It’s vital to notice that the drain into this tank is rather modest in diameter. Take all necessary precautions to guarantee that food particles do not end up in the sewer. Even something as little as a pea has the potential to block a drain.

Black Water Tank

You should only ever empty your tanks at a dumping site that has been authorized for that purpose. There are a few basic rules of thumb to follow in order to keep the dreaded black tank from causing problems:

  1. Single-ply toilet paper should be used. Two-ply might cause a blockage in the tank. Flush the toilet on a regular basis, always adding water to the bowl before flushing
  2. After you’ve dumped your tank, disinfect it. Special chemicals for this may be found in the RV area of any large box shop
  3. However, they are not inexpensive. Pouring a garden hose down the toilet is a good way to keep this tank clean. This should assist in flushing your system and clearing out any buildups that have occurred.

Although draining sewage may not be a part of your RVing dreams, it is a very real and necessary element of the RVing experience. Ideally, it should be a short and painless process if everything is done correctly. Follow the instructions above, and after a few trips to the dump station, you’ll be an expert at dealing with your RV’s septic system! Even though emptying your RV’s tanks is not a pleasant task, it is an essential aspect of RV life. Are you apprehensive about the prospect of emptying your own recreational vehicle tanks?

Is It Legal To Dump RV Tanks At Home?

It is permissible to dump RV black and grey water tanks at your residence, but the wastewater must be discharged into a domestic sewer system that has been approved. There may be unique municipal restrictions in place in different places, and as a responsible RV owner, you should check into these before emptying your tanks. As long as you dump your tanks into a sanitary sewage line or into the municipal sewer system, you should not have any concerns. Never empty your RV tanks into a storm drain since storm drains are commonly connected to reservoirs, which should be avoided at all costs.

Draining your tanks into storm drains increases the danger of local water pollution, which might result in a large fine from the city, as well as a few choice words from your enraged neighbors.

Is It Legal To Dump RV Tanks Into My Septic System?

In the event that you are not connecting your RV tanks to the main municipal sewage line, you do have the option of directly connecting your RV tanks to your septic tank. Think about if you’re using ecologically friendly detergents and soaps, because harsh chemicals in the wastewater might kill beneficial microorganisms in your septic tank, which is something to keep in mind. Some environmentally friendly choices may be found by reading our evaluations of the top RV black tank treatments.

How To Dump Your RV Tanks At Home – 4 Practical Methods

The most common techniques for emptying your RV tanks at home are as follows: There are pros and downsides to each approach, and each method differs depending on whether you dump your tanks into the main sewage system, a septic tank, or use a bucket or macerator pump to dispose of the waste. Let’s take a deeper look at how to dump RV tanks at your house in this article.

The Residential Sewer Line and Septic Tank Methods

The majority of individuals have access to a sewage disposal system, whether it be public or private. In contrast to a private sewage disposal system, which is similar to a septic system, a municipal sewage disposal system is similar to a residential sanitary line or main sewer line. Both sewer systems are equipped with a cleanout, which is a tiny pipe that protrudes from the ground and connects to the main sewage line or septic tank and is sealed with an end cap. Following are the procedures to be followed when dumping your holding tanks into any of these sewage systems:

  • Locate the access point for the septic tank or sewage line. This procedure may necessitate the use of a heavy wrench and the assistance of others. Set up your RV next to the access port and attach the garbage disposal line to the black water tank. Protective face and hand gear should be worn to ensure that you remain protected and clean. Connect the other end of the output line to the access port on the septic tank. When removing sewage end caps, take your time since potentially dangerous gasses may escape. Ascertain that the output hose is pointing downward into the access port and that it is sufficiently secure to prevent waste from shooting out of the sides. Before you begin emptying your black water tank, double-check that you are on the solid waste side of your sewage system and not the storm drain side to prevent pouring potentially hazardous trash into a storm drain. Activate the valve to completely drain the black water tank, making sure it is entirely empty
  • Clean out the black water tank with fresh water, and then completely drain the tank. After you’ve finished with the black tank, you may go on to the grey water holding tank and repeat the process described above. Because the soap and detergent residue in the graywater will clean the dumping hose, it is recommended that you always empty the black tank first, followed by the grey tank. Before detaching your dumping hose from the sewage connection, thoroughly rinse the inside of the hose. Remove the sewage hose and store it in an appropriate location.

Check out our step-by-step instruction on how to connect and utilize an RV sewage hose for a more in-depth explanation of the procedure. Please note that you should only use the septic tank approach if you are confident that your grey and black water do not include strong chemicals or soaps that might kill the important bacteria found in your septic tank. Before beginning the process, always double-check that you are permitted to dump into your septic tank or public sewage line in your region of residence.

If you want to improve hygiene standards and keep things extra clean, we recommend that you invest in a flush valve for your toilet.

The Bucket Method

Check out our instructions on how to hook up an RV sewage line and utilize it for a more in-depth, step-by-step explanation. Please note that you should only use the septic tank approach if you are confident that your grey and black water do not include strong chemicals or soaps that might kill the beneficial bacteria found in your septic tank. Before beginning the operation, always double-check that you are permitted to dump into your septic tank or public sewage line in your neighborhood. We also recommend that you communicate with your neighbors to inform them that you are dumping into the sewage line rather than the storm drain to avoid confusion or confrontation later on.

It is recommended that you get a flush valve if you want to improve hygiene and keep things extra clean. Solidified waste is removed from the bottom of the RV’s black water tank via these valves, which prevents the tank from filling up sooner than it should be.

  • Ensure that you have protective hand and face protection on before filling the bucket with grey and black water. Prevent the bucket from being completely overfilled. Carefully pour the bucket into your house toilet and flush it to ensure that all waste is removed. Walk slowly and carefully so that none of the bucket’s contents is spilled on the ground.

However, while the bucket approach is the most straightforward and cost-effective dumping option, it is also the messiest and most time-consuming to use. This approach is most effective for emptying smaller holding tanks, while bigger holding tanks require a more time-consuming and difficult operation.

The Macerator Method

This technique of dumping is a little more involved, but it makes the work of emptying your holding tanks a lot more manageable in the long run. Unlike a standard pump, a macerator pump will not simply push away waste. Moreover, it aids in the churning of solid waste, making it easier to dispose of and letting you to utilize virtually any size hose. This video demonstrates how to utilize the macerator pump technique at home in step-by-step detail. Do you need to empty your RV’s black tanks at home?

To summarize, the macerator pump approach looks somewhat like this:

  • Before anything else, connect the output hose of the black water holding tank to the input valve of the macerator pump. In order to complete the installation, attach an extension hose to the outlet valve and drag the hose’s end to your sewer inlet or toilet. Activate the macerator pump by opening the black water tank’s output valve and turning it on

Use a clear elbow so that you can see when the flow is interrupted. You don’t want to take the chance of damaging the macerator pump by leaving it running empty. If you choose for this option, be prepared to invest a significant amount of money on a macerator pump set, which may run into the hundreds of dollars.

BenefitsRisks Of Emptying Your RV Tanks At Home

The most major advantage of emptying your RV tank at home is that it is more cost-effective than using a dumping station, and you will not be charged any fees. This is not to say that it is really convenient! For those times when you have visitors staying over, you may turn your RV into an extra room or permanent home addition. The most significant downside of emptying your RV tanks at home is the danger of leaking raw sewage, which is especially true if you employ the bucket technique of dumping your tanks.

However, this is true regardless of whether you are disposing at home or at a dumping site.

Consequently, be certain that you are adhering to all applicable regulations or you might face a significant punishment.

How Often Should You Dump the RV Black Water Tank?

Due to the fact that the frequency with which you need to empty your tanks varies depending on how frequently you use your toilet and the size of your black water tank, there is no general solution to this topic. If you travel by yourself most of the time, you might be able to go for a week or longer without having to dump. However, if your RV has smaller holding tanks or if you are camping with a big group of people, you may need to empty your black tank every other day or more frequently. Most recreational vehicles are equipped with a sensor that indicates how full your grey and black water tanks are.

Allowing the tank to get overflowing might result in your black tank leaking and other problems.

This will guarantee that any solids have adequate time to decompose, and the weight of the trash will make it simpler to empty the waste container.

How Do You Empty Your RV Tanks At Home?

A straightforward inquiry with a couple of straightforward responses.

The septic tank approach is by far the most straightforward, but it is only effective if you already have a septic tank. (Do you have one?)

Where To Dump RV Waste

The vast majority of the time, you’ll likely empty your tanks while driving. We provide a comprehensive guide on locating and utilizing RV dump stations. First, look to see whether there is a waste site in the vicinity. Unless you have a septic tank or intend to frequently dispose of garbage at home, the quickest and most convenient approach is to make a brief journey to the dump station for disposal. In most regions, it is permissible to dump your RV’s black tanks at your residence (google to double check).

  • If you suspect that dangerous chemicals or detergents have gotten into your black tank, call your local water department right once.
  • If you believe there is a risk that this may be an issue, you should proceed cautiously and employ the macerator procedure.
  • In this case, it is effective since the trash makes its way to your local sewer system.
  • According to the regulation of the Environmental Protection Agency (EPA), your municipality may or may not have integrated sewage and rainfall drains.

RV Waste: Bucket Method

Let’s pretend it’s the beginning of spring. You’ve just gotten back from a one-night trip in your RV, which was your first outing this season.

When you first started, the black and grey tanks were completely depleted. There is some, but just a little amount, of garbage now. Rather than having to travel to a dump site, you may simply empty your tanks at your residence. By using this strategy, you will be in the forefront of the threat.

  1. Parking your RV as close to the house as feasible (within reason) is recommended. Set aside a pail and put on some disposable gloves. Place the bucket beneath the waste outlet of your RV
  2. And Fill the bucket only two-thirds of the way. You don’t want to make a mistake and spill something. Make sure you bring it inside the restroom with care. Dump the contents into your toilet (while flushing)
  3. Repeat as needed.


Human excrement has the potential to spread illness. There are several cautions throughout this site concerning the procedures you may take to avoid the possibly unlawful and deadly repercussions of dumping your black and grey tanks. Please read them carefully. Human waste is classified as biowaste due to the fact that it may serve as a vector for both viral and bacterial infections. If it gets into sources of drinking water, it can pose a major health concern to those who consume it. According to the World Health Organization (WHO), about 2.2 million people die each year as a result of illnesses caused by polluted drinking water.


How To Empty Your Tanks: Macerator Method

We’ll go through our favorite approach, which is the macerator method. We believe it is the most basic and practical method for all types of garbage.

What You Will Need

Even if you are not visiting a dump site, you will want materials that are similar. The most significant change is that you will use a macerator to grind through the waste material instead of a grinder. Then it’s flushed down the toilet.

The Macerator

We recommend Flojetis as our recommended macerator for disposing of RV garbage. We like them since they are a simple system to set up and operate, which makes life easier for us. It is intended to be used in conjunction with garden hoses. If you exclusively discharge your trash at home rather than at transfer stations, you will not require a sewage hose kit.

Flojet Details

Here are a few things you should know about this particular Flojet model.

  • As soon as it begins to overheat, this system will shut down immediately. An on/off switch and a six-foot cable are included with the purchase. It should not be used for “hard, solid items, sanitary napkins, or rags,” according to the manufacturer.

For further information, consult the owner’s handbook. You can get theFlojet maceratorhere. If you are experiencing technical issues, please contact us at 978-281-0573.

SewerFlo: A Great Alternative

If you already have an RV sewage hose, SewerFlo has a model that is less expensive. It is an excellent product; however, it does not function with a garden hose output. SewerFlo is equipped with a strong pump and macerator that connects with a simple twisting motion. Experienced RVers who already have the necessary equipment for frequent dump stations will find it to be an excellent alternative. Consider the following scenario: you’re new to RVing and don’t yet have a sewage hose. If you want to discharge trash at home as well as at dump stations (while on the road), the SewerFlo model and an RV waste hose are recommended.

Both SewerFlo and Flojet have received overwhelmingly positive reviews from the RVing community.

As a side note, both Flojet and SewerFlo manufacture units that may be equipped with garden hose inlets for the purpose of cleaning the macerator.

The distinction is that Flojet discharges macerated waste through a garden hose, whereas SewerFlo discharges macerated waste through a bigger RV waste pipe. Check out this tutorial for information on how to repair and maintain your RV macerators.

Other Equipment

In addition to the macerator, we propose the following pieces of equipment (which you probably already have).

Item (Our Top Choice) Purpose
Gloves Stay clean and stay healthy
Wipes Clean valves, handles, and connection ports
Black/Gray Tank Flush Hose Used to flush out tanks during/after draining them**
Sewage Hose Garden hose / RV sewage kit hose (see notes on macerators for which you should use)
Tank Treatment Used to prevent odors in your tanks (especially your black tank)

**The flush hose and the sewage hose are two different hoses. It’s nothing more than a garden hose. You will attach it to the macerator so that it can be rinsed and the waste can be moved. Do not utilize any line linked to your RV’s sewer system for portable water storage or dispensing.

The Process

The time required is 30 minutes. The proper way to empty the black and gray waste tanks of your RV at home.

  1. Choose the Proper Macerator If you have an RV sewage hose, you may utilize the pump macerator from SewerFlo. If you prefer to utilize garden hoses, Flojet’s macerator is a good choice. Connect Your Macerator to Your Recreational Vehicle Connect the macerator input to the waste output of the RV by screwing or twisting it into the appropriate location. Additionally, connect the power cord. Flush hoses should be connected to the macerator. There are three ports on your macerator for connecting devices. The first is the waste input (connected in step 2). The second is the intake for the rinse water (for both types of macerators, this can be a garden hose). You are free to connect it at this time. This hose connects to the side port that protrudes from the side of the vehicle. In order to assist in rinsing waste through the macerator and all the way to your disposal location, this ‘flush’ should be performed every few minutes. Connect the Macerator’s waste output hose to it. If you choose Flojet, the business end of the macerator is equipped with a garden hose, and if you choose SewerFlo, the business end is equipped with an RV sewage hose. Insert it by twisting or screwing it in place. Check to see that the other end of the hose is at the location you desire. The toilet is the most frequented location. Open the RV Waste Disposal Ports Both the black tank and the grey tank should be represented by two different values. Open each one one at a time. First and foremost, empty the black tank. It will clean up the lines and rinse out any debris completely when you dump the grey water tank in this manner. Turn on the Macerator if it is not already on. This is a self-explanatory statement. If the macerator is required to drive the trash uphill, there is a risk that it will overheat before the waste is entirely removed from the tanks. Don’t be concerned. With one click, Flojet will be turned off. Then wait a few minutes for it to calm off, and you may get back to work. Organize Yourself Afterwards, disassemble your RV’s septic system and wipe off the whole system using disinfectant wipes. You may learn more about unplugging from the internet by reading our lengthier advice. You’ve advanced to the level of an expert.


What exactly is a recreational vehicle septic tank? RV septic tank is another word for the combination of the black waste tank and the gray waste tank. They work together to form the sewerage system of your recreational vehicle. Is it possible to discharge the waste tanks from your RV at home? Answer in a nutshell: yes. The long and the short of it is that you must execute things right in order to prevent significant repercussions. If you have a septic tank in your house, the process is rather basic.

Otherwise, you’ll need a macerator, which will make it much easier to empty your tanks whenever you want.

Why Dump RV Tanks At Home?

My quick response is that it is more convenient and cost-effective to dump your RV tanks at your residence. Please do not reenact the scene from Chevy Chase’s National Lampoon’s Christmas Vacation movie, in which the Griswald’s cousin Eddie dumps his RV garbage into the city’s streetside sewage, since this would be inappropriate. Don’t ever do something for the same reason that you see in the movie. The best element, apart from the fact that it is cost-effective, is how simple it is to complete at home.

The obvious consequence is that the environment will be polluted.

It is also possible that the municipality will face sanctions. Because it is not difficult to empty your RV tanks at home, it is important to remember to always utilize proper disposal procedures when disposing of waste water from your RV.

Is it Legal to Dump My RV Tanks at Home?

Most of the time, it is permissible to dump both your RV’s black and gray water tanks into a residential sewer system that has been permitted. It is possible that there are municipal rules and limits, and you should investigate them. The black and gray water from your RV, on the other hand, is virtually identical to the water that comes from your toilets and sinks at home. Providing that you are disposing of your waste into a legitimate municipal sewage line, sometimes known as a “sanitary line,” you should have no difficulties.

These are frequently dumped into reservoirs, and doing so might land you in serious problems, including a large fine.

As well as contaminating the environment, doing so can result in some rather steep fines as a result.

Can I Dump My RV Tanks Into My Private Septic System?

If your home is equipped with a septic system, you can also discharge the contents of your RV’s waste holding tanks into your septic tank! You can safely empty both your gray and black tanks into your septic system without fear of contamination. Just be aware that there are some critical considerations you will want to keep in mind in order to ensure that both you and the bacterial environment of your septic system remain healthy. The benefit of using your home’s sewer system is that you can also dump your gray water into it, which is a great feature.

It is not necessary to worry about the composition of dish soaps, shampoos, cleaning products, and toilet paper when using them in a conventional sewer system.

It is not all items that are compatible with a septic system.

Using antibacterial soaps at home is not recommended if you have a septic system, which is something that the majority of people are completely unaware of.

Types of RV Tanks

Before we get into how we may empty our RV water tanks at home, I’d want to talk about the numerous types of RV water tanks that are available. Many of you are novice RVers, and you may be wondering what the difference is between black water, grey water, and freshwater tanks, among other things.

  • Your RV’s black water tank holds the filthy sewage and waste water that comes from your toilet. The grey water tank in your RV collects waste water from your shower, sinks, and other sources such as when you wash dishes or brush your teeth. Fresh Water Tank– This is, without a doubt, the cleanest tank in your home, and it is responsible for supplying fresh water to your faucets and shower.

Check read our post What Are RV Holding Tanks and How Do They Work for a more in-depth explanation of the many types of RV tanks.

What Is Black Water?

As previously stated, RV black water is the waste water that is discharged from your toilet sewage system (also known as human waste). Make sure to empty your RV’s black water tanks first! Why? Because you will be able to utilize the gray water tank to semi-clean and wash out your hose at that point.

What Is Grey Water?

Grey waste water is generated by the drains of your kitchen sink, shower, and bathroom sink. Almost all of the recreational vehicles are equipped with all three types of water tanks: grey, black, and fresh water. There’s a chance that you’re driving a vintage trailer camper that doesn’t have a grey water tank. If this is the case for you, you may actually purchase and install a grey water tank in your house.

Do I Really Need to Use RV Safe Toilet Paper?

Your kitchen sink, shower drain, and bathroom sink drain are all sources of grey waste water for you to dispose of. Grey, black, and fresh water tanks are found in almost all recreational vehicles. A grey water tank may not be present in your antique trailer camper, on the other hand. A grey water tank, which may be purchased and installed if this is your scenario, is an option.

1. Dump You RV Tanks into the Cleanout Pipe

The vast majority of people have access to a sewage disposal system, whether it be private or public. A private sewage disposal system is commonly referred to as a septic system, whereas a public sewage disposal system is referred to as a domestic sanitary sewer or a residential sewer system, respectively. Cleaning out is something that nearly always occurs with both sorts. In the image on the right, you can see the results of a cleanout. It may seem similar to a sewage cleanout that you have seen at a campsite, and the concept is precisely the same as well.

  • In the case of a septic system, you are permitted to dump without first confirming that it is permitted in your jurisdiction.
  • As a good neighbor, I recommend informing your neighbor that you have examined your sewer tank and that you will be dumping it on a regular basis in the near future.
  • When we go away for the weekend, however, there are no connections available, so we end up dumping at our residence instead.
  • It is also strongly recommended that you get a RhinoFLEX Rhino Blaster that has a gate valve to make cleaning your black water tank more convenient.
  • After that, we purchased a RhinoFLEX Rhino Blaster.
  • The amazing thing about the Rhino Blaster is that we can connect a garden hose directly to it, which allows us to fill the black tank in record time.

The answer is to get a Rhino Blaster that includes a gate valve. When the gate valve is closed, it keeps water in the tank, allowing you to open the black tank valve and fill the tank with clean water, which then flushes out the black tank. It is a time saver and really convenient at the same time.

2. The Bucket Method

The bucket approach is the quickest and most straightforward, but it should only be utilized if you have no other option for emptying your tanks. However, you will be in direct contact with raw sewage if this is the case, and you should exercise caution while using the bucket approach. It is fairly straightforward:

  • Obtain a bucket
  • Carefully drain the tank of your RV into the bucket until it is completely empty
  • Fill your toilet with the contents of the bucket and flush it
  • Continue until the tank is completely depleted. Empty the pail of water

Clearly, this is a simple method of emptying your tanks at home. While it may not be pleasant to empty the black tank, if you only have a little amount of gray water to dispose of, it isn’t that unpleasant. Additionally, as with any dumping procedure, it is essential that you wear gloves during the operation. The finest gloves I’ve discovered so far are the Heavy Duty Orange Nitrile 8 Mil Disposable Gloves with Diamond Texture, which are available at Amazon. The majority of disposable gloves are just 4 to 6 mm thick, and they frequently rip or tear.

However, the 8 mil rubber gloves are considerably more durable, and the diamond grip is wonderful as well.

3. The Macerator Method

As you can see, this is a basic option for emptying your tanks at home. While it may not be pleasant to empty the black tank, if you only have a little amount of gray water to get rid of, it isn’t too horrible a situation. As with any dumping approach, it is essential that you wear gloves during the operation. Heavy Duty Orange Nitrile 8 Mil Disposable Gloves with Diamond Texture are the most comfortable gloves I’ve discovered thus far. Disposable gloves are typically 4 to 6 mil thick, and they are prone to tearing or rippling.

However, the 8 mil rubber gloves are far more durable, and the diamond grip is excellent.

  • Hose adapter
  • CDFJ adapter
  • Garden hose (it is advised that you use a separate garden hose for this and not the same garden hose that you use for your lawn and garden)
  • RV waste macerator pump

Instructions Provided in Step-by-Step Form In order to gain a better angle and better monitoring of the contents of the tank, you may attach the hose adapter to your RV’s waste outlet. 2.After that, connect the macerator to your waste outlet. 2.Connect your pump to a power source (These can often be connected to your RV batteries). 3.Connect the garden hose to the macerator with the help of the CDFJ adapter. 4. 4.Connect the yard hose to the toilet at your residence. The use of a larger-diameter hose and a more powerful pump is advised for traveling long distances.

  • 6.Always be prepared to flush the toilet as frequently as necessary.
  • It is at this point that the transparent adapter is beneficial.
  • 9.
  • Upon completion, switch off the pump and unhook all of the wires and connections.

4. The Septic Tank Method

When it comes to dumping your holding tanks into a septic system, the best technique is probably the simplest.

If you have a cleanout, it’s also the quickest. The cleanout is a PVC pipe that is above ground and has a screw cap on the end to keep out debris. There’s a cleanout between the home and the septic tank where you may go.

Using the Cleanout

The cleanout on your septic system is the most convenient way to gain access to your septic system. Remove the screw-on cap and connect your RV hose to the cleanout in a secure manner. Make certain that it is properly fastened. Having the connection come loose when you’re emptying your wastewater tanks is not something you want to happen! Once you have everything connected, you can opt to leave it connected in the same manner as you would in any RV park. You can also take it down after you are through.

Using the Septic Tank’s Access Port

If utilizing the cleanout isn’t an option, you may alternatively utilize the access port on your septic tank to drain the tank. This strategy, on the other hand, is not nearly as appealing. Carefully remove the lid from the container. It is possible that two persons will be required to lift the lid. Make a point of staying away from any of the gases that are produced. They have the potential to be lethal. Be careful to dump into the access port on the side of the baffle that takes solids when utilizing the access port to discharge solids.

It is important to note that you should not keep your RV plugged in when using the Access Port due to the fumes and the danger of harming the beneficial bacteria in your septic system.

When using your septic tank, it is critical to avoid breathing the toxic gases that come from it, and to always utilize the side of the tank that gathers solids (the side nearest to the house).

How Often Should I Empty My Black Water Tank?

If you believe that you will only have to empty your RV’s black water tank once throughout your vacation, you are mistaken. When your RV’s black tank is at least two-thirds full, or more, it’s time to dump it. Using your tank sensors, you can keep a check on the levels, and then you can go ahead and empty your tanks.

Can I Leave My Black Tank Valve Open?

This is a question we are asked all the time, and the answer is no. When you are linked up to a water source when camping or at home, you should not keep your black tank valve open. Some of the waste in the black tank is solid, and the pressure created by a nearly full tank is necessary to drive the waste out of the tank and into the sewer connection, which is located nearby.

Can I Flush My Black Tank at Home?

Excellent question, and the answer is yes. After you have emptied your RV’s black tank, now is the ideal time to fill it with clean water and flush it out to verify that the tank is completely empty. In the long run, this will prevent trash from accumulating inside your tank. In all seriousness, you’ll want to do regular upkeep and maintenance on your RV waste tank to avoid running into difficulties later on that are both expensive and inconvenient to deal with if you’re in the middle of nowhere!

Just keep in mind that the plumbing in your RV is very different from the plumbing in your home, which is connected to the municipal sewer system.

Your RV holding tanks are undoubtedly one of, if not the most, crucial components of your camper since they are responsible for making it possible to use your bathroom and kitchen in an efficient and safe manner.

What to Do if You Don’t Have Tank Level Indicators?

Fortunately, the standard holding tank capacities for RVs are very enough. As a result, if you have a 15-foot canned ham camper, your tanks will be smaller in comparison to those of a large Class A recreational vehicle. No matter what size holding tanks you have, your owner’s handbook or RV dealer will be able to provide you with the necessary information. Every RV spouse or family will utilize their holding tanks in a somewhat different way than the next. Because it is based on your individual usage, the amount of time you may go between dumping your black and gray water tanks will vary from person to person, depending on your circumstances.

Very tiny and outdated trailers, on the other hand, are unlikely to have a tank sensor system built in to them.

A very essential guideline to remember is that no matter how tempting it may be to dump before the containers are totally filled, you should always wait, especially during the cold winter months when smaller volumes of waste water are more likely to freeze and cause a backup.

BenefitsRisks of Emptying Your RV Tanks At Home

The advantages of emptying your RV tanks at home include convenience and cost savings (some dump stations do charge a small fee). One of the hazards of doing so is that you will inappropriately dispose of your RV garbage and will wind up having to pay a fee to the city or will cause damage to your property. Nevertheless, if you follow our recommendations, you should not have this problem.

How to Stay Safe While Dumping RV Tanks at Home

The prospect of disposing of your RV’s black water, grey water, and fresh water tanks may be enough to make you want to throw up in your mouth. If this is the case, don’t give up on your RVing dreams just yet. There is yet a ray of hope! The most effective method of staying safe is to avoid coming into touch with any waste water at all. In order to avoid the sewer hose from popping out of the sewer connection, make sure all of your connections are tight, use gloves, and wash or sterilize your hands once you are through working.

Check out our post on “What are RV Sewer Hose Weights?” for more information.

What About Dumping Gray Water at Home?

Yes! You may also dispose of your grey water tank at home! Here are some pointers on how to properly dispose of grey water at home.

  1. Always empty the grey tank first, followed by the black tank. By doing so, you will be able to fully rinse and flush the black water and any residual particles via the hose. Taking the time to fill and flush your grey tank is also recommended.

Another thing to keep in mind is that you can leave your grey water tank valve open while you are connected to a sewage system. Because grey water does not contain any solid trash, it will drain freely and without causing any obstacles. You only need to stop the grey valve at the conclusion of your journey to allow the grey water to fill the tank and be used to flush the black water via the sewage line.

What if I Can’t Dump My RV Tanks at Home?

Dump stations are frequently available on the grounds of campgrounds, state parks, and national parks where people are staying for extended periods of time. As a result, you may have to wait in line to empty your tanks. However, I have stayed at some locations where there was no dump station, although this is quite unusual.

Another alternative is to download the RV Dump Station Finder App, which allows you to identify dump stations near you no matter where you are and to empty your tanks before you return home after your trip.


As you can see, emptying the waste tanks of your RV at home is not a difficult task, and there are various options for accomplishing the task. Also obvious is that if your property is equipped with a septic system that has a cleanout access point, you are much ahead of the game. Keep in mind that there are several aspects, as well as some genuine risks, that must be taken into consideration in order to guarantee that the dumping procedure runs as smoothly and safely as it possibly can. For many RV owners, the possibility of emptying their RV’s tanks at home is a viable and attractive choice.
