Is it Acceptable to Ever Dump an RV Holding Tank or Toilet into a Home Septic System Tank?

A portajohn or small, portable chemical toilet into a home septic tank is not something we would hesitate to do on occasion – because the volumes are so small (typically two gallons or less in total), the deodorizers or disinfectants in that small container would be so dilute that they would have no effect on the bacteria in the tank. However, an RV is a different story, not just in light of the customary state standard on discharging chemical toilets into the environment, but also in light of the fact that the holding tank is far larger.

I’d contact the company and request any material they may have on the subject – if you receive anything from the maker of your product, please provide it to me.

“The answer is yes, provided that your septic system is completely operational, appropriately proportioned, and properly maintained.

We also recommend that you only dump one RV holding tank into a residential septic system every week, due to the fact that holding tank waste is highly concentrated and takes longer to degrade than other garbage.” – Thetford Corporation retains ownership of the copyright.

How Much Holding Tank Deodorant Chemical to Use

Keep an eye out for overdosing a tiny portapotty or chemical toilet with an excessive amount of RV toilet or RV holding tank deodorizer or disinfectant. A standard ColemanTM chemical toilet package provides enough dry powder to treat a 40-gallon chemical toilet holding tank, such as the type used on an RV or travel trailer. Coleman’s PORTABLE TOILET INSTRUCTION MANUAL offers information on how to properly use a holding tank deodorizer. The toilet instruction handbook recommends mixing one 2-oz dry powder packet with one pint of water before flushing the toilet.

  • If your portapotty has a capacity of only a few gallons, such as 4 gallons, you may get away with using significantly less.
  • However, the little chemical toilet holding tank that we have shown you above can only contain roughly two to three gallons of waste.
  • The toilet will not be damaged if you use excessive disinfectant, but if you want to empty your tiny toilet into a household septic tank, you should avoid putting in more disinfectant or deodorant into the septic tank than is necessary.
  • Users of chemical toilets or RV waste holding tanks who are using antibiotics or other bacteria-killing medications should exercise caution while emptying their waste holding tanks or RV waste holding tanks into septic tanks to avoid a problem.

Calculations and Data to Evaluate the Effect of Dumping RV Holding Tanks Into a Septic Tank

This is lacking a more academic explanation that incorporates real-world evidence, such as the following:

  • RV tank capacity in gallons
  • Concentration and chemistry of disinfectant/deodorant agent used in RV tank
  • Septic tank capacity in gallons
  • Daily wastewater flow other than from RV dumping that will be available to dilute the RV chemicals
  • Concentration of RV disinfectant chemicals in the septic tank
  • Typeof septic system – mound, recirculating sand bed, aerobic, or onsite wastewater treatment mini plants may be used
  • The size of the RV tank in gallons
  • The concentration

What are the problems if we empty an RV or other waste holding tank into the septic system?

The concern with dumping RV disinfectants or any chemical into a septic system is that high concentrations of a disinfectant may not only harm the natural bacterial and other actions that occur in the septic tank, but it also has the potential to harm the biomat that forms under the drainfield and is essential for proper drainfield functioning. In the case of some chemicals, there is also the possibility that the chemical itself is a pollutant in the environment. You can see why New York State, and maybe other states, have chosen the viewpoint that has been outlined below.

For example, consider the following: Fill your RV tank with water and dump it into the septic system only once, keeping a note of the volume of water used and the other information provided above in the process.

Install a riser port at the septic tank pumping entrance if you don’t already have one so that you may use the same riser port as a dumping station if you don’t already have one. You’ll simply unscrew the top from the riser pipe and attach your RV dumping hose to the exposed end of it.

What else should we do to avoid Damaging the Septic System with our RV?

  • It is not advisable to drive your RV over septic fields or tanks since this can cause damage or possibly ruin them. It is also advisable to check your septic tank pumping schedule. A pumping schedule is provided atSEPTIC TANK PUMPING SCHEDULEwhich indicates when it is necessary to clear out the septic tank, and the septic tank pumping technique is described atSEPTIC TANK PUMPING PROCEDURE- A Detailed Guide to Pumping and Cleaning Septic Tanks.

NOW: Because you’re dumping sewage into your septic tank along with deodorant (which is likely to slow down sewage breakdown), and because we don’t have any quantitative data from the manufacturer about how many RV gallons can go into a septic tank of any given size (I doubt they know), I would respond by moving up my septic tank pumping schedule to a more convenient time.

How Do You Empty Your RV Tanks At Home?

A straightforward inquiry with a couple of straightforward responses. We favor the macerator technique, although there are other options, such as the bucket method or the septic tank method, to consider. 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).

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

You should never dump the contents of your black or gray tanks into a storm drain, regardless of the situation. Lastly and most importantly, curbside systems are unquestionably storm drains, not sewage drains. There are strict regulations regarding the disposal of RV black tank trash.

RV BlackGrey Tanks: Septic System

When you’re traveling by RV, having a septic system is a fantastic convenience. If you know where your septic cleanout line is located, you should be able to empty it directly into your holding tank. ” alt=””> ” alt=””> Septic systems, on the other hand, are quite situational. Here are a few points:

  • When you’re traveling by RV, having a septic system is a must. The cleanout line from your septic system may most likely be connected directly to your tank, if you know how to locate it. The alternative text for this is “alt=”” But septic tanks are very dependent on their surroundings. Here are some items to consider:

When you’re traveling by RV, having a septic system is a must-have. If you know where your septic cleanout line is located, you should be able to discharge it directly into your tank without any problems. ” alt=””>” alt=””> Septic systems, on the other hand, are extremely situational. Here are a few items to consider:

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 following items, in addition to the macerator, are recommended: (which you probably already have).

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.


Choose the Proper Macerator for Your Needs Utilize SewerFlo’s pump macerator if you have an RV sewage hose. You may use Flojet’s macerator with garden hoses if you prefer that method of cleaning. Your RV’s Macerator should be connected to it. Screw or twist the macerator input to the RV waste output connection to secure it in place. Ensure that you have also connected the power cord. Flush hoses should be connected to the Macerator. Currently, your macerator has three available ports. the waste input being one of them (connected in step 2).

  • Make the connection as soon as possible.
  • In order to assist in rinsing trash through the macerator and all the way to your disposal location, this ‘flush’ should be performed after every use.
  • If you choose Flojet, the business end of the macerator is equipped with a garden hose, whereas SewerFlo is equipped with an RV sewage hose.
  • Ascertain that the other end of the hose is at the location you choose.
  • Activate the RV Waste Disposal Stations There should be two values: one for the black tank and another for the gray tank.
  • First and foremost, empty the black tank.
  • Start the Macerator by pressing the button.
  • The macerator may overheat if it is required to push the trash uphill before the waste can be entirely emptied from the tank.
  • Automatic shut-off of the Flojet will occur.
  • We have a longer guide that has more information about disconnecting.

How Domestic Septic Systems Work

Septic systems are utilized when centralized sewer systems are not within walking distance of a person’s house or business. They are sewage treatment buildings that are buried below and are responsible for breaking down organic debris and dispersing wastewater. This construction is extremely efficient and resourceful, thanks to the presence of a holding tank and the presence of nature.

  • In situations when centralized sewer lines are not within reach of a homeowner’s house, a septic system may be installed. They are sewage treatment buildings that are buried below and are responsible for breaking down organic stuff and dispersing waste. This construction is extremely efficient and resourceful since it is equipped with a holding tank and is surrounded by natural beauty and wildlife.

In situations when centralized sewer systems are not within reach of a person’s residence, septic systems are employed. They are sewage treatment buildings that are located underground and are responsible for breaking down organic debris and dispersing wastewater. This building is extremely efficient and resourceful since it is equipped with a holding tank and has nature on its side.

What if I use chemicals in RV waste water tanks?

As a result of the atmosphere created within the tank, this is a highly organic and raw system that functions well. The chemicals in your RV’s contents are a source of worry when disposing of it. We may put chemicals in our tanks to help with the decomposition of trash and paper, however these chemicals can be harmful and disrupt the natural biome in our septic tanks if used improperly. Septic wastewater treatment systems contain organisms that are both aerobic and anaerobic in nature, and they both contribute to the decomposition of organic materials.

  • Both are required for survival due to the fact that they absorb various microorganisms.
  • If the bacteria in the tank are removed, the tank will become unbalanced.
  • Backflow, obstructions, and flooding in the drain field would result as a result of this.
  • To put it another way, you aren’t the one who is responsible for the upkeep of the campsite.
  • Also, depending on how much time is spent in the main home and how much time is spent in the RV, you should be aware of the additional use and be prepared to have the tank pumped more regularly.

The key to keeping a septic system happy and healthy is to perform regular maintenance and pumping. Depending on the size of your tank, the normal pump schedule is every two to three years, depending on usage.

How to dump RV waste into house septic systems

As a result of the atmosphere created within the tank, this is a highly organic and raw system that functions well. There is a concern about the chemicals when you dump your RV’s contents. Waste and paper-breakdown chemicals that we put in our tanks might possibly be harmful to the natural biome in the septic tank if they are not properly handled and maintained. Both aerobic and anaerobic organisms are found in septic wastewater treatment systems, which aid in the decomposition of organic debris.

  • Because they eat different germs, both are required for survival.
  • If the bacteria in the tank are eliminated, the tank will become unbalanced.
  • Flooding and backflow in the drain field would result as a result of this.
  • To put it another way, you aren’t the one who is responsible for the upkeep of your campsite.
  • It is also important to be aware of the additional use that will occur due to the installation of the RV and to plan ahead of time to have the tank pumped more regularly as a result of this.
  • It is recommended that you have a pump installed every two to three years, depending on the size of your tank.

Use caution when using a house septic system access port

It is possible to remove the cover of an access port if your septic system is not equipped with a cleanout. This may be exceedingly dangerous due to the fact that the gases in the tank are potentially lethal. Bring a friend who can assist you in removing the lid and carefully emptying your tank. Not only is it unsafe to keep your RV hooked up in this manner, but too much air might kill the anaerobic organisms that aid in the breakdown of organic matter if you do. In the event that you want to dump your tank into the access port, make certain that you dump on the right side of the baffle.

You’ll want to dispose of your waste at the access port that is nearest to the residence.

What about dumping RV gray water into house septic systems?

The benefit of putting your black water in your septic tank is that you can also dump your gray water in there. As long as you are utilizing septic-friendly goods that are easy to break down, you should have no problems emptying both tanks. It is not need to worry about the composition of dish soaps, shampoos, cleaning products, and toilet paper when they are used on a standard plumbing system since they are safe to use. The kind of goods that you use on your sewage system, on the other hand, should be taken into consideration.

It is not all items that are compatible with a septic system. By being sensitive to the waste disposal that occurs naturally, you may ensure that your septic system lasts for an extremely long period.


In conclusion, yes, it is permissible to discharge RV waste water into residential septic systems. Use of chemicals in your black water tank may result in the destruction of the natural ecology in your tank. When dumping from an access port, make sure you’re on the proper side of the baffle to avoid damaging the port. Solids will be kept away from the outlet as a result of this. Finally, you will have the ability to empty both your black and gray water tanks. Keep in mind to use septic-safe soaps and detergents so that your tank can break down the goods as effectively as possible!

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

When dumping RV black and grey water tanks at home, the wastewater must be sent to a domestic sewer system that has been certified by the city. There may be unique municipal restrictions in place in different places, and as a responsible RV owner, you should research into them before emptying your tanks. No complications should arise if your tanks are dumped straight into a sanitary line or a municipal sewer system.

Storm drains, which frequently run to reservoirs, should never be used to dispose of RV tanks. 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 neighbor’s mouth.

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

Following these procedures will allow you to dump the tanks in your RV using the bucket method:

  • 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:

  • It is a little more difficult to use this way of dumping, but it makes the work of emptying your holding tanks a lot more doable. In addition to pumping out garbage, a macerator pump may also pump out water. Moreover, it aids in the churning of solid waste, making it easier to dispose of and allowing you to utilize virtually any hose diameter. It is explained in detail in this video how to operate the macerator pump at home. Do you have RV black tanks that you need to empty at home? Certainly, it’s attainable! The macerator pump approach can be summarized as follows:

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.

Furthermore, it is possible that it is against the law in your location to empty your tanks at home. 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.

  1. Allowing the tank to get overflowing might result in your black tank leaking and other problems.
  2. 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 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 sewage hoses and attachments. 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.

In order to avoid this situation, you may find yourself emptying the black water every second time you dump the grey water. 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.

  • This may be used not just to flush the black tank, but it will also perform wonders for cleaning the grey tank as well.
  • The tank level sensor can only function properly if the tank walls are substantially free of debris.
  • 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.
  • If you see clear, non-opaque water pouring out of the drain pipe, this means that the tanks need to be flushed.

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

The black can be discharged and drained once the grey has accumulated a sufficient volume of water from showering and basic everyday usage, which may occur the following day or the day after that.

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 economy. This procedure, on the other hand, necessitates the use of a black tank that is at least half full. Prepare to hit 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 aids in the removal of buildup as well as the maintenance of a clean tank and the creation of a less adherent surface for the growth of bacteria.
  3. Macerators are now standard as an option on many popular RVs, and they are becoming increasingly popular.
  4. So, what exactly 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 household toilet, provided that it is within reach of the discharge hose.
  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.

Types of RV Tanks

Before we get started, let’s take a short look at the various types of RV water tanks. According to general definitions of tanks, there are three main types of tanks, each of which serves a specific purpose:

  • The RV black water tank retains wastewater and sewage from your RV toilet
  • The gray water tank keeps filthy water from your shower and sinks
  • And the freshwater tank holds pure water from your faucets and faucet fixtures. That’s the RV water tank, which is responsible for supplying water to your RV kitchen and shower.

How to Empty the Tanks and What to Buy at the RV Parts Store

Following your understanding of the operation of each individual RV waste tank, you should learn about the procedure for emptying them.

  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
