How To Clean Out An RV Black Water Tank (5 Simple Steps)

You can use all of the air fresheners in the world to mask the stench emanating from your RV’s black water tank if you have not been fully cleaning it. This is due to the fact that a black water tank is analogous to a home’s septic tank, and a failure to clean it will result in the smell of its contents drifting back into your RV. Even worse, a neglected tank can result in plumbing problems as well as the growth of deadly germs that can be detrimental to anybody who comes into contact with it.

Let’s get this party started.

How To Clean An RV Black Tank

Because the contents of your black tank are potentially harmful, you should avoid breathing any vapors or allowing any of it to come into contact with you or your clothing. Protect your hands and eyes by donning rubber gloves and safety glasses before beginning the cleaning procedure. Shoe coverings and a face mask are optional, but highly recommended protective gear for the job site environment. Preparing for the worst case scenario includes having soap and running water available nearby for cleaning up after the work.

Step 2: Empty the Tanks

Cleaning the RV tanks is the first step after putting on your safety gear. The next step is to disinfect the RV. We urge that you do this before the tanks become overflowing, since the extra content may harm the tank or piping, resulting in your black tank bursting and flooding your home. If the tank is overflowing, you will be unable to add water to liquefy solid waste and avoid blockages while the tank is being drained. On the other hand, make sure your tank is at least two-thirds of the way full before driving.

  1. When it’s completely filled, it’s much simpler for the solids to break down and drain.
  2. If you are emptying the tank at your residence, please see our tutorial on how to empty an RV black tank at home for more information.
  3. This end is designed to go inside your RV, while the “L” shaped elbow end is designed to fit into the dump station inlet.
  4. Helpful hint: Use an RV sewer hose support device to direct your line in a downward direction.
  5. Following the installation of the sewage line, proceed as follows:
  • Close the valves for the black water tank and gray water tank, and then fill the gray water tank with water. To empty the black tank, open the valve on the side of the tank. Once it has been emptied, open the gray tank valve and let the water from it to flush the sewage pipe.

Follow these guidelines to prevent getting into difficulties with other campers while draining your black tank:

  • Remember to be courteous to others around you at the disposal station. Due to unruly behavior, dump stations around the country have been forced to close their doors. When flushing your waste tanks, avoid using potentially dangerous compounds such as formaldehyde. It causes harm to your tank and to the equipment at the dump site. Close the black valve until you’re ready to dump, and then close it again soon after you’ve finished. Do not flush the black water tank or sewage hose using the drinking water hose that came with the RV. It is possible that using it for these reasons will pollute your fresh water source.

Step 3: Soften and Remove Waste Tank Buildup

Waste tank accumulation should be removed at least once a week, if not more frequently. The trash will cake on the edge of the tank if this is not done. This will result in clogs, foul odors, and other issues. Then, when you have emptied the waste tank, close the drain outlet and begin the process of removing the buildup by flushing the toilet until 3/4 of the black tank is full. Following that, we just need to apply your preferred black tank treatment, which may be anything from a liquid enzyme cleaning to your ownhomemade holding tank solution to pouring two cups of liquid bleach into the tank through the toilet.

Make cautious not to leave the water/bleach combination sitting for more than 10 minutes and to properly rinse away the bleach.

After 10 minutes, drain the tank’s contents and instantly refill it with water before emptying it once again to complete the process.

Making certain that the bleach smell has vanished assures that no bleach residue will damage your plumbing or storage tank.

If you complete this step on a regular basis (weekly), the chances are good that your tank will be entirely cleaned up and you will be able to go ahead to step 5. However, if there is still build-up in your black tank, we will need to backwash it, as explained in step 4 of this procedure.

Step 4: Backwash the Black Tank

Backwashing is a comprehensive cleaning procedure in which pressured water is used to remove all waste from the black tank’s walls and floor. This cleansing is incapable of surviving even the most solid caked waste, especially after the previous bleach cleaning. Depending on the design of your RV, you may either use the built-in rinser system or purchase a handheld backwasher that connects to a water line to backwash the tank.

Using the Built-In Rinser

If your RV is equipped with a built-in cleaner, connect it to a water hose and turn on the pressure washing valve on the coach. Maintain system operation until clear water may be seen flowing via the clear hose adapter (if applicable). Keep in mind that this is only a basic suggestion because built-in rinsers differ from one RV to the next. You can refer to your RV’s rinser handbook for more extensive instructions on how to clear out your RV’s black water tank at this step of the procedure.

Using a Handheld Backwasher

The majority of portable devices are in the shape of a wand that may be inserted into the toilet tank to pressure wash the interior of the tank. To make use of the wand, follow these steps:

  • Connect it to a water hose that has been hooked into a faucet
  • Close the faucet until the wand has been flushed down the toilet
  • Once the wand is in the tank, turn on the water supply. Move the wand around the tank to ensure that every conceivable corner is pressure washed
  • Continue until all debris has been removed from the waste traveling through the clear hose adapter.

The quality of the product will determine how fast and successfully you can do the task using a portable backwasher. The Camco Flexible Swivel Stik comes highly recommended.

Macerator System

The quality of the product will determine how fast and successfully you can complete the task using a handheld back washer. The Camco Flexible Swivel Stik comes highly recommended by us.

Flush Valve

A backflow preventer is incorporated into the system, which allows it to perform the same functions as a macerator system. It is so effective that it may be used to break up and remove obstructions, as well as to clean the sensors in your tank. You may get a flush valve that can be installed and removed without the use of tools for each use. Alternative options include purchasing a system that may be permanently installed on your RV and connected to the tank.

Step 5: Prepare The TankToilet

As the final step in ourHow to Clean Out an RV Black Water Tankguide, we prepare the toilet and tank for usage until the next cleaning is completed. First and foremost, make sure that all of the drain lines are closed to prevent waste from spilling everywhere you travel in your RV. After that, fill and flush the toilet four or five times to completely fill the bottom of the black tank. This is important because if you don’t, the initial garbage that you put in would harden and adhere to the bottom of the bin, causing clogging troubles later on.

Cleaners that employ enzymes to expedite the decomposition of trash are known as macromolecular biological catalysts (enzymes).

Taking use of all of these advantages will make your next black water tank cleaning a lot less difficult.

Enzyme cleansers, in contrast to solutions that include formaldehyde or other harsh chemicals, do not cause harm to water tanks or other components of your plumbing system. You may purchase it in a variety of forms, including liquid, pill, capsule, and powder, depending on your desire.

Final Tips on How To Clean Out an RV Black Water Tank

The above information should cover everything you need to know about how to clean out an RV’s black water tank. Not to be overlooked is the fact that your black tank drain must stay connected to the sewer drain throughout stages 2, 3, and 4. A messe on the ground (or worse, on you) might result if you don’t take the proper precautions. In addition, you’ll need a clear sewer hose adaptor. In the absence of one, the only method to determine how clean the tank is during each flush is to open the drain line while waste is being discharged from it.

Take the style of your toilet into account as well while selecting a handheld backwasher.

If the tank is not immediately beneath the toilet, use a tank rinser that is flexible and can be bent to enter the tank at an oblique angle.

RV Waste Tank Dumping Tips

  • When executing the deed, put on disposable plastic gloves to protect your hands. If you throw away your gloves before entering your RV, you will prevent any possibility of transmitting bacteria. Instruct children, grandkids, and visitors on the significance of using an RV toilet in a safe and responsible manner. Except for a person’s buttocks, human feces, and septic-safe toilet paper, there should be nothing else around or within the toilet. Make use of toilet paper that is suitable for septic systems. RV toilet paper that is manufactured particularly for marine grade and RV toilets is available for purchase. Alternatively, Scott’s single-ply TP is septic-safe and may be used in recreational vehicles. Choose the RV waste water tank cleaning procedure that you believe will be most effective for you.

Although it may come as a surprise, it appears that there are a hundred different tried and proven techniques for keeping an RV’s black tank clean. Perhaps you’ve tried a couple of them before, or perhaps one or two of them will spark your curiosity.

The basic treatments to keep RV black tanks clean

Make use of these tips to keep your RV’s black tanks clean.

Ice Cubes and Detergent

Many years have passed since the ice cube notion was first floated around in the public domain. Some people just fill their RV tank with 2 to 3 bags of ice cubes and then head out for a trip. Add a quarter cup of dishwashing detergent (NOT antibacterial version) and 2 liters of water to the tank along with the ice cubes, according to the hypothesis, which has been further developed.

When it comes to the sort of liquid soap to use, it appears that Dawn or Joy brand detergents receive the most responses. RVers then just drive for 2 to 4 hours before dumping their tanks and flushing their toilets at a full-hookup park.

  • Don’t use too much detergent at once. Alternatively, your RV toilet and sink may begin to froth.

Baker’s Yeast and Peroxide

Make use of baker’s yeast and peroxide to get rid of the sediments and odors in your black tank. Add 1 gallon of water, 4 ounces of yeast, and 10 ounces of peroxide to an empty black tank and stir well. During the time when the water/yeast/peroxide is splashing around in your black tank, go for a drive, possibly to your next camping area. Fill the tank with water once it has been emptied. After that, simply apply your regular black tank treatment ingredient.

  • It has been observed that this approach may effectively remove sediments and odor, but not paper.

The GEO Method

Adding a water softener to the ice cubes and detergent treatment suggested above may be a good option to try. Calgon is a brand that many people are familiar with. This is referred to as the GEO approach. Many RVers have had great success using this strategy. Pour 2 cups water softener into each tank once it has been completely emptied and the valve has been closed. Repeat for each tank. Pour the gray tank’s contents into your sink or shower, and the black tank’s contents into your toilet. The water softener prevents junk from adhering to the interior of your tank as well as to the sensor circuitry.

Add 1 cup of the original “blue” Dawn dishwashing soap if you want to go the extra mile.

This aids in the subsequent cleaning and deodorization of the tank.

  • Several RVers also add a quarter cup of Borax to the black tank in addition to the detergent. Borax is a fantastic cleaning product that can be found in most households.

Simply use your tanks as you normally would and empty them when they are two-thirds of the way filled. All of these items are both safe and environmentally friendly. The GEO approach can be utilized on a “as required” basis or every time you empty the black water tank, according on your preferences.

Best RV Waste Water Tank Cleaning Tools of the Trade

Perhaps you choose to make use of one of the several RV black tank treatments that are available on the market today. In the event that the tank’s readings continue to be inconsistent, these handy tools may flush and clean RV black tanks with great effectiveness.

Built-in Waste Tank Rinse System

Many recreational vehicles (RVs) are equipped with their own built-in rinsing mechanism, known as a black tank flush. If your system includes this feature, it is activated by connecting a separate hose to the black tank flush input water valve and flushing the tank. During the flushing process, leave the black tank valve partially open. Using this method, you may avoid having water overflow into your RV sinks and toilets. This approach is analogous to power washing your black tank to ensure that it is fully cleaned.

RV Hydroflush

There is a black tank flush in many RVs, which is a self-contained system for rinsing. The procedure is carried out by connecting a separate hose to the black tank flush inflow water valve, if yours is equipped with this feature. While completing the flush, leave the black tank valve open.

There will be no flooding into your RV sinks or toilets as a result of doing so. When it comes to fully cleaning your black tank, this approach is akin to power washing your black tank. Consult your RV’s owners handbook for specific information. –

  • The Hydroflush is equipped with a reverse flow preventer that has been pre-installed as well as a separate anti-siphon valve. It helps to keep the freshwater supply safe from pollution.

Tornado Rotary Tank Rinser

There are legitimate advantages and disadvantages to this product. The results are identical to those of any built-in rinse system, but the negative is that the installation process is somewhat complicated. In order to install it, you’ll need to drill a hole in your black tank. From the best thing ever to ideas on constructing components out of metal rather than plastic, which may potentially break, to the fact that it only partially cleaned the sensors, the reviews are varied. When you consider that the installation entails drilling a hole in your black tank, correctly sealing the hole, and then praying for the best outcome, it appears to me that there are better options on the market to test first.

Tank Wands

Tank wands make life a lot less complicated. When you attach the tank wand to an outside water hose, you may use it to clean and flush the RV’s black water tanks. Pass the hose through an open window to the inside of your RV. To power rinse the interior of the tank, open the toilet bowl flush valve and insert the wand into the tank from the inside. The flow of water is controlled by a valve on the handle. When you’re finished rinsing, wipe the wand clean. Flexible wands are the most effective for power cleaning the tank; nevertheless, certain tanks are positioned in such a way that a straight wand is required for power cleaning.

There are also instructions for making your own tank wands available online.

  • On the market, there are various brands that range in length from 23″ to 42″ long, such as the Camco RV Flexible or Straight Swivel Stik or the Valterra Master Blaster. It is recommended that you invest in a tank wand with brass components to minimize rusting.

Quick Tips to Flush and Clean RV Black Tanks

  • Keep in mind to wipe the “O” ring seals on the gray and black sewer caps as well as the caps themselves. After that, you may apply a thin layer of oil to the seals to prevent any black or gray water from dripping
  • Always put a small amount of water to the black tank once it has been emptied. Thus, any residue on the bottom of the tank does not have a chance of drying out and hardening. Each and every time the black tank needs to be flushed and power washed, this is not essential. You’ll learn how to create a timetable that is appropriate for your RV. Keep the valves closed until you’re ready to empty the tanks, then open them. Aeration of your tank helps to prevent sediments from drying out. Additionally, it reduces odor leaking. It is not necessary to dump your tanks until they are at least 12 percent filled. Solids can drain out of the tanks if there is adequate water in the tanks. If you are leaving a site and need to empty the tanks, but they are not at least 12 percent full, you may need to add water to them. Never, ever use your fresh water hose to empty your tanks – not even once. Get yourself a transparent RV dump elbow that you can connect to the tank valve. This aids in determining whether waste water seems to be clear. Continue to flush the toilet with water until the waste water has been flushed away. Do you have a blocked black water tank? Our article on cleaning a clogged tank is complete with step-by-step instructions and pictures, so have a look at it as well. You may read the article here.


There are several ways and instruments available for flushing and cleaning RV black tanks, as well as for ensuring that they continue to function properly. Find the one that works best for you in order to keep smells at bay, waste water sensors operational, and waste water valves operational.

How to Dump and Deep Clean Your RV’s Sewer Tank in 5 Easy Steps

A very experienced RV owner, I understand the need of keeping my RV tanks clean and sanitized on a regular basis. To keep your camper, travel trailer, or motorhome smelling fresh, you must understand the proper ways for cleaning and disinfecting the waste water tank in your vehicle. An improperly kept sewage tank develops germs that cause foul odors to permeate the inside of a motorhome and can cause obstructions in the plumbing system. Both of these issues make traveling in an RV a terrible experience, and both of these issues may result in expensive repairs.

This is a job.

  • Not only is it not difficult, but it also takes very little time
  • It will keep your RV smelling fresh, and it will keep your plumbing system operating efficiently.

The good news is that if you follow the advice in this article, you won’t even have to get your hands filthy.

Step 1:Protect Yourself

Because the substance that comes out of your sewage hose is hazardous, you must take precautions to protect yourself and your clothing by using rubber gloves, shoe coverings, and protective eyewear, among other things.

It’s a good idea to have some liquid soap and a roll of paper towels on available so that you may wash your hands, gloves, and shoe covers at an outdoor faucet once you’re finished with the task and before getting back into your coach.

Step 2:Prepare to Dump

Due to the toxicity of the waste that comes out of your sewage line, you must take precautions to protect yourself and your clothing by wearing rubber gloves, shoe coverings, and safety glasses. It’s a good idea to have some liquid soap and a roll of paper towels on available so that you may wash your hands, gloves, and shoe covers at an outdoor faucet after you finish the task and before you go back into your coach thereafter.

  • If you are at a dump station, attach the sewage hose to your RV and then insert the other end of the hose into the sewer hole
  • Otherwise, proceed as follows: It is probable that your sewer line will already be connected to your sewer outlet if you are camping at a full hookup location.

You can connect your RV’s sewer hose to a dump station and then insert the other end of the hose into the sewer opening if you’re at a dump station. You will most likely find your hose already attached to the sewage outlet if you are camping at a full hookup site.

Step 3:Empty Your Tanks

It is critical to empty your tanks before they become full since liquid is heavy and a buildup of liquid in your tanks might cause harm to your tanks. A gallon of water has an approximate weight of 8.34 pounds. For example, if your tank contains 45 gallons and you wait until it’s completely filled, it will weigh more than 375 pounds, which is more than enough weight to be an issue in some situations. You may avoid this problem by dumping when each tank is no more than half filled, as described above.

  1. It is critical to empty your tanks before they become full since liquid is heavy and a buildup of liquid in your tanks can cause damage to the tank walls and bottom. It takes around 8.34 pounds to fill a gallon of water with water. For example, if your tank contains 45 gallons and you fill it to capacity, the tank will weigh more than 375 pounds, which is more than enough weight to create a hazard. Dumping your tanks when they are less than half full will help you prevent this problem. Cleaning and sanitizing tanks on a more frequent basis can also assist you avoid blockages as a result of doing so.
  • You should close the blackwater valve, add a gallon of water and some Spic N Span to the sewer tank, and leave the gray water valve open if you intend to remain in your current location. Alternatively, if you want to drive your coach after dumping, shut both valves and pour an enzyme cleanser into the sewage tank along with approximately one gallon of water

As you drive, this combination will become more concentrated.

  • It will slosh about and eat away at any hardened debris in the tank, as well as sanitize the tank and aid in the elimination of obstructions.

The removal of any scents that may have permeated your coach will make traveling in it a much more pleasurable experience.

Step 4:Deep Clean Your Sewer Tank

The majority of people believe that emptying their tanks on a regular basis is sufficient to maintain them clean and fragrant, but this is not the case. It is necessary to empty the bus every few days and to deep clean it at least once a week whether it is being used for travel or as a place of residence. In order to thorough clean, you must follow all of the processes given above, with the exception of draining the waste water tank fully prior to opening the gray water valve.

  1. Fresh water and two cups of liquid bleach are added to the container until it is 3/4 full. Closing the toilet lid will prevent you from inhaling in any hazardous gases. Wait no longer than 10 minutes after adding the ingredients. Drain the tank of water
  2. Fill it up with new water once again, then drain it quickly
  3. And Continually fill and drain the container until the clear hose connection is clear and the bleach scent has vanished completely. Performing this step is extremely crucial because you must ensure that there is no bleach residue left behind that might cause harm to your plumbing system.

Numerous sources would advise you not to use bleach at all since it might cause harm to the plumbing pipes and fittings, but I have been employing this technique for over fifty years with no problems whatsoever. The key is to constantly combine it with a large amount of water and then remove it totally as soon as you can after mixing it with water. The bleach is breaking down the thick muck that has adhered to the tank’s walls and floor, releasing the gases that you can see rising. In addition to cleaning your tank, using bleach may help to sterilize it, which is extremely essential for your overall health.

Step 4:Backwash Your Sewer Tank

In order to thoroughly clean a sewage tank, the final step is to backwash it.

In order to remove and flush away hardened sludge and other materials from the tank’s inner walls and floor, you must use pressured water to push against those surfaces. There are two options for accomplishing this.

  1. Make use of a system that is already integrated into your unit. Make use of hand-held equipment that is connected to your hose.

Built-In System Directions:

To utilize your coach’s system, connect a green garden hose to the system connection on your RV and turn on the pressure washing valve, which may be found on the outside of your vehicle. Ensure that your clear hose adapter indicates that the water is running clear by continuing to run the water.

Directions for Using a Wand:

In order to utilize an RV tank cleaning wand, you must first remove the tank from the vehicle.

  1. To use your campsite’s water spigot, connect a green garden hose to it
  2. Connect the backwash wand to the hose
  3. And draw the wand and hose through a window or door into your bathroom. the toilet should be opened and the wand should be inserted into the entrance
  4. Have someone standing outside turn on the water for you
  5. And keep moving the wand back and forth around the tank until your assistant notices that the waste is flowing freely

You won’t be able to perform a decent job of pressure washing unless you use aclear sewage hose adapter because this device allows you to see when the hose discharge is free of dirt and waste matter. Using aclear sewer hose adapter will save you time and money. For years, my husband and I have relied on a product manufactured by Camco (can you tell that we are fans of that brand?). It’s affordable, long-lasting, and accomplishes exactly what we need it to do. Other brands also perform admirably, but because Camco goods have consistently performed admirably for us, we choose to use them whenever feasible.

Backwashing Equipment

Many recreational vehicles are equipped with built-in backwash systems, all of which perform well.

  • If your coach is equipped with one, the manufacturer’s maintenance manual will explain you how to use it. If you do not already have one of these machines, you will need to purchase a wand that is specifically designed for RV tank pressure cleaning.

TheFlexible Swivel Stik, created by Camco, is one of numerous types of wands that my husband and I use since it is swivels and has a manual shut off, making it more easier to use than other kinds of wands. It is reasonably priced, is simple to keep, and performs admirably. Because it eliminates the need to divide the pressure washing operation between two people, we’ve been using it for years and find it to be far superior than the more rigid varieties that do not have shutdown valves. This is a must-have item for those whose coaches do not come equipped with a built-in navigation system.

When depositing at a dump station, use the same procedure as described above.

Step 5: Use Enzyme Treatments

Once a tank has been dumped and thoroughly cleaned, it should be treated immediately with an enzyme cleanser that is favorable to biological organisms. As a general rule, depending on the size of your tank, you should empty it every three to five days, so you won’t need to apply this product on a daily basis. This product, on the other hand, is what will make future cleanings easy for you and will keep the stink in your tank at bay. Simply drop a packet into your tank and fill it with one gallon of water to get started.

  • In order to facilitate the movement of waste water through your plumbing system and into a sewer, they soften and transform it into liquid.
  • When this occurs, you may find yourself dealing with problems that are expensive, stinky, and inconvenient to resolve.
  • Some of these sorts of problems might grow so severe that repair technicians will have to disassemble parts of your system in order to remedy them.
  • Tank cleaning is made more easier and faster with the help of enzymes.
  • These do not cost any more than other options, but they are just as effective and just as simple to use.

The liquid version was previously my go-to, but the packets have shown to be just as effective and are much easier and cleaner to use than the liquid form. Learn how to utilize a disposal station in the appropriate manner. CC By 2.0, via of Flicker

RV Black Water Tank: 6 Things You Need to Know

An very crucial piece of equipment in your RV is the black water tank, which can be found underneath the vehicle and contains the waste water from your toilet. However, while it’s not everyone’s favorite thing to think about when they “go,” it’s a big part of what makes RVing so much more easy and fun than traditional vehicle travel or tent camping – no more having to rely on stinky pit toilets at the campsite! If you want to ensure that your RV’s black water tank is always operating correctly and efficiently, there are a few things you should be aware of regarding how it is designed to function.

before you depart.

1. What is an RV Black Water Tank?

The majority of self-contained recreational vehicles are equipped with two types of waste tanks: a gray water tank and a black water tank. A gray water tank is a container that catches the water that drains from your RV’s shower and sink drains. It is the presence of soap residue and dirt in this wastewater that gives it its name and gray-ish appearance, respectively. Check out this page for additional information about grey water tanks. Rather than the gray water tank, we’re more interested with the black water tank, which collects the effluent from your RV toilet.

When you use your RV’s onboard facilities, you won’t have to worry about being continually connected to a sewage line since this tank will take care of that.

Because the black water tank gathers both liquids and solids, it requires a different level of maintenance than the gray water tank.

What you should use instead is RV-specific toilet paper, which is more easily degradable and less likely to clog your rig’s delicate plumbing system!

2. How do I Clean my RV Black Water Tank?

Knowing how much waste is contained within your black water tank, the next obvious thing to ask is: how in the world do you maintain it clean and free of odors? What are the finest chemicals for cleaning the black water tank in an RV or other recreational vehicle? Is it necessary to use bleach? Fortunately, the widespread availability of commercial chemicals and deodorizers makes it quite simple to keep your black tank in good working order on a regular basis. In order to properly prepare for your camping vacation, you need add a dosage of RV black water tank treatment, which may be in liquid form (such as Aqua-Kem) or in packets that look similar to Tide Pods (such asthese).

  1. These chemicals not only have the potential to reduce tank smells, but they also have the power to break down solid waste and toilet paper.
  2. Apart from keeping your black water tank in good condition using these cleaning methods, it’s also a good idea to deep clean your tanks on a regular basis, possibly between camping excursions or before putting your RV into storage.
  3. The process is typically the same: drain your waste tank entirely before filling it three-quarters full with new water and a small bit of bleach, Pine-sol, or laundry soap.
  4. This final step should be repeated until the water flows clean.

Consider using ice cubes or hot water, for example; go here for more information on how to unclog an RV potty completely.

3. How Often Should You Dump and Empty Your Black Water Tank?

When you have to go, you have to go – and the same may be true about your recreational vehicle! It goes without saying that the exact frequency with which you need to dump and empty your tanks will vary depending on your needs, just as the frequency with which you need to go will change. Depending on your circumstances, you may be able to go up to a week or more without dumping the tanks if you’re traveling alone and regularly spending days outside the RV adventuring. You may find yourself emptying the tank every other day or so if you’re camping with a large group of people (or traveling in an RV with a tiny tank capacity).

  • This comprises the black water tank, as well as the gray water and potable water holding tanks, among other components.
  • Instead, when the water level rises, you simply sort of.figure out that it’s time to do something.
  • After all, you don’t want to park your RV with wastewater in the tanks!
  • Let’s start with a step-by-step walkthrough of how to empty the black tank in your RV’s toilet.

To empty the black water holding tank in your RV, follow these steps:

  1. First, put on a pair of rubber gloves to protect your hands. It’s better to be safe than sorry. Connect one end of your sewage drain line to the black tank valve on the back of your recreational vehicle. the hose’s other end is connected to the valve at the sewage line or disposal facility Pulling the valve to empty the black tank and letting it to drain entirely is recommended. To clean the black tank, fill it with water and flush it. According to your arrangement, you may be able to accomplish this with water from your gray water tank. Completely drain off the tank’s water supply
  2. Steps 2-4 should be repeated with the gray water tank. Close the valve on your RV’s water tank and remove the hose from the tank
  3. Before detaching the hose from the sewage connection or dumping station, thoroughly rinse the interior of the hose. Remove the sewage hose and put it in a safe place

5. What is RV Black Tank Flushing?

Some RVs are equipped with a built-in RV black tank flush system, which allows you to attach a hose directly to an intake valve and use it to effectively power wash the tank. This makes it extremely simple to keep your tanks clean and free of contaminants. The flush valve should only be used in accordance with the manufacturer’s instructions to ensure that it is used appropriately. Most guidelines advise leaving the black tank valve open in order to prevent water from backing up and flooding your RV through the toilet!

After-market options for this sort of vehicle exist in a variety of forms and sizes.

Finally, if you don’t have a manufacturer’s tank flush valve and don’t want to put one in your tank yourself, you’ll have to resort to a more manual approach of cleaning your RV’s blackwater tank.

6. Portable RV Waste Tanks

If you plan to stay in the same location for an extended period of time without access to sewage services, you may find it necessary to use a portable RV waste tank. It is possible to transfer the contents of your black and grey water tanks into an external tank, which can then be transported to a dump station, using these waste tanks. RV portable waste tanks are often equipped with wheels and a handle, allowing them to be conveniently moved about the campsite for disposal. If you utilize a portable RV waste tank, it is vital to remember that cleaning and flushing the tank should be performed with the same care as cleaning and flushing the onboard RV black water tank.

How to Clean an RV Holding Tank: 7 Tested Methods that Actually Work!

On one of our first RV trips, my kid accidentally flushed half a roll of toilet paper, tube and all, down the toilet of our camper. Fortunately for me, it was jammed only a few inches away from the bottom of our RV’s black tank. I was able to reach down and pull it out of darkness with my hand. I’ll never be able to look at my hand in the same way after that. Because I’m a full-timer and have a family of six, it made me question, “What else is down there?” “And how do you get it out?” I inquire.

A black tank rinse after every flush, organic enzyme treatments, reverse flush pressure washing, and borax bath bombs are some of the solutions.

Why Clean Your RV Holding Tanks?

In the process of cleaning your tanks, you should also clean your RV sensors. It is possible for toilet paper, sludge, and misplaced hygiene items to obscure sensors, resulting in false positive readings. If your sensors are not working properly, you may be emptying your tank too soon or waiting too long. When your black tank is at least two-thirds full, it’s time to empty it. Do not leave your waste valve open if you are connected to a sewage system! Water is your best friend when it comes to cleaning out the black tanks.

  1. Pooping in a dry black tank is never a good idea!
  2. It is a satisfying sensation to see the words “ALL TANKS EMPTY” on your control panel.
  3. Last but not least, consider Murphy’s Law.
  4. You may do this either when you are getting ready to go on a trip or as you are pulling into a campground for the night.
  5. You’ve worked hard for your trip; don’t let ignored plumbing problems mar it.

How Do You Clean Your RV Black Tank?

This is a question I often ask when I meet full-timers who have been doing it for a long time. I enjoy learning new things and being encouraged that my efforts are sufficient. And every now and then, I hear about a procedure that is so outlandish that it just could work!

My Preferred Method: a Black Tank Rinse

When it comes to prevention, I strongly think that an ounce of prevention is worth a pound of cure. Following is my “secret sauce,” my go-to approach for keeping my tanks clean and my sensors reading properly throughout the year. It’s time to cleanse the black tank. It’s straightforward, but if you do it on a consistent basis, you’ll prevent the need for more complex solutions.

  1. Connect a dedicated garden hose to the black tank flush valve to prevent clogging. Make certain that this line is designated for usage with the black water tank! Never use your drinking hose to flush your black tank
  2. Instead, use a garden hose. Closing the black and gray tank valves in your RV after you have emptied both the black and gray tanks is a good idea. Allow for 5-10 minutes of continuous water flow before opening the black tank valve. Set a timer or designate someone to keep an eye on the toilet inside. Don’t let things get out of hand! Things are about to go wrong. Through a transparent sewer elbow, you can see the water flowing. It should be free of blemishes and imperfections.

Psst. Not sure how to empty your tanks? Here’s a hint: Check out my other article on how I empty my tanks, which includes photos! If the quality of the water running through the elbow and our control panel’s data indicate that this procedure should be repeated, I will do so. What happens if you don’t have access to a black tank rinse? Another possibility: you haven’t cleaned your tanks in a year or so. Visit the links below to learn about some of the alternative options that have been tried and proven by full-time RVers like me.

So please use caution! Don’t give out any confidential information, and please come back to us at Tips for the Dump Station if you have any questions.

Be Courteous at the Dump Station

If I’m at a dump station and there are people in front of me, I’ll usually forgo the black tank flush to save time. No one wants to waste their camping weekend standing in line to dispose of their waste.

Use the Correct Water Supply

In addition to water for doing black tank flushes, some dump stations also supply fresh water for filling your fresh water tank. Watch out for the two and hope that no one else has made the same mistake as yours yet.

Hydrate! Hydrate! Hydrate!

The water at certain dump sites may be used for both black tank flushing and filling the fresh water tank in your RV. Take care not to confuse the two, and pray that no one else has done so before you.

Do You Need RV Toilet Paper?

Science teaches us that this is not the case. Wandering Weekends put a number of different brands to the test (see video below). It was discovered that great value septic safe toilet paper was the best RV toilet paper based on factors such as value, comfort, and ability to dissolve. Even though the wipes are labeled as flushable, never flush them down your RV toilet. Simply dispose of them in their garbage bin. A large number of RVers do not flush their toilet paper. The used toilet paper is instead disposed of in your bathroom’s garbage can by the staff.

It’s still not something I’m willing to do.

For Help, Ask a Professional

Each and every person I’ve encountered on the road has been eager to offer their knowledge, have a look at your setup, and demonstrate their own. I attempt to soak in as much information as I can, weed out the nonsense, and put what works to use. Because of the toilet paper incident, I’m keeping a close eye on the restroom. Despite the fact that I am not confident in my children’s ability to keep foreign things out of the black tank, I am confident in the procedures we employ to keep our tanks clean.

As far as I can tell, my children are all preparing to become professional eaters.
