In RV ownership, disposing of RV garbage is one of the more difficult, yet required, aspects. If you own or are staying on a property that has a septic tank, this may be a convenient choice for disposing of waste materials. Yes, it is possible to dump RV trash into a home septic tank; however, there are certain hurdles and important actions that must be done in order to avoid serious problems. Before you dump into a septic system, you should do your study, learn about your septic tank and RV, and obtain the necessary materials to do it safely and effectively.

Listed below is a comprehensive guide on using your septic tank in a safe and effective manner while dumping RV waste into a residential sewage system.

RV Holding Tanks

To ensure that your RV waste is properly disposed of, you should be familiar with your RV holding tanks and plumbing system. The majority of recreational vehicles include three holding tanks: one for freshwater, one for blackwater, and one for greywater. Freshwater is defined as “clean” water that is utilized within the RV for purposes such as cooking, bathing, and other activities. Even when the RV is not connected to a water supply, this delivers water to the occupants. The difference between blackwater and greywater is that blackwater is wastewater (think toilet), and greywater is “used” water from all other activities (other than waste), such as showering, cooking, running the dishwasher, and so on.

Cleaning out the tanks and keeping them from freezing are particularly critical jobs when it comes to RV ownership and maintenance.

Fortunately, there are several simple techniques for cleaning out your tanks, as well as heaters that may be fitted to keep your tanks from freezing.

The fact that you should never mix up your hoses between separate tanks (especially freshwater and blackwater) may seem like simple sense, but it’s crucial to remember!

How Does A Septic System Work?

It’s critical to understand how a septic system works before putting one in place. A septic system is a type of private sewage system that is placed beneath the earth. It is common for septic tanks to be in the shape of a huge box and to be constructed of a durable material such as plastic, concrete, or fiberglass. People install septic tanks on their properties generally if they live too far away from a central sewage system or if a central system is not possible or practicable for their situation.

  1. It also comprises pipes, a baffle to avoid blockages and to distinguish between solid and liquid waste sections within the tank, and a drain field, via which waste is discharged back into the environment.
  2. Chemicals are seldom employed in a septic tank; instead, the tank provides a natural environment for waste breakdown and makes use of microorganisms to accomplish this task instead.
  3. Septic systems must be emptied on a regular basis in order to eliminate solid waste that does not flow out into the drain field and into the drain field.
  4. Septic tanks, on the other hand, only need to be emptied every few years (depending on the system).
  5. In addition, septic tank owners must exercise caution when planting certain trees and bushes near the tank since the roots of these plants might cause damage to the tank and pipes.

They should also avoid placing anything too heavy on the ground where the tank is located. As a result of your newfound knowledge of a septic system, here are some things to keep in mind while considering putting your RV trash into a septic tank.

Is it Legal to Dump your RV Tanks in your Home?

The laws governing the disposal of RV waste in your septic system differ from state to state and from municipality to municipality. Some states and municipalities do not permit the establishment of a “home dumping station.” Check to see if the problem is simply a matter of language or if there are more serious difficulties. The legality may differ depending on the language you choose or the sort of tank you’re dumping in (black or graywater). The best course of action is to inquire with your local municipal or town office about rules.

Besides the possibility of causing environmental damage and/or introducing illnesses into a community, you might also be punished for illegal dumping.

A Word About Chemicals….

Septic tanks are designed to operate mostly without the need of chemicals. In order to survive, they must rely on aerobic and anaerobic bacteria as well as a careful equilibrium within the tank. As a result, it is not recommended that chemicals be dumped into your septic tank. This has the potential to drastically change the ecosystem within the tank, resulting in significant difficulties down the line. If you compromise your system, you may be forced to totally replace it, which would be an extremely expensive and time-consuming endeavor.

When dumping blackwater into a septic tank, it is necessary to avoid using toilet/tank cleaning solutions.

If you are also dumping your greywater tank, you must use goods (dish soap, cleaning products, shampoo, and so on) that are septic-friendly and will not harm the ecology in your tank when you are dumping your greywater.

What items are safe for septic systems may be found in abundance on the internet, according to the experts.

How To Dump Your RV In The Septic Tank

Most septic tanks do not require the use of chemicals to function properly, though. They rely on a careful mix of aerobic and anaerobic bacteria in the tank to survive. Chemicals should never be flushed down the toilet or disposed of in any other way. In the long run, this can entirely change the ecosystem within the tank, resulting in expensive problems down the line. Your system may be forced to be replaced entirely if it is compromised—a costly and time-consuming endeavor. For toilet cleaning and deodorizing purposes, many campers utilize chemicals that are placed in their RV’s toilet and blackwater tank.

Fortunately, there are more environmentally friendly options available to consumers.

Before acquiring or utilizing a product, you can conduct research. There is a wealth of information available on the internet concerning which items are appropriate for use in septic systems. Listed below is an article that is useful on the subject.

2. Finding The Cleanout Pipe And Attaching Your RV Tanks

In order to properly dispose of your RV waste in your septic tank, you must first locate the “cleanout” line or access port to your septic system. The cleanout pipe is located on your property and is often composed of PVC. It is critical that you use the proper pipe, and it may be preferable to check with a professional prior to dumping your waste. Connect your waste pump to your RV’s electrical system, and then connect a hose that will attach to or run into the septic tank cleanout pipe. You may remove the cap and connect your RV sewage hose to this pipe by unscrewing it.

You should keep in mind that you may need to use blocks or other props to ensure that the waste is directed downhill into the cleanout pipe (particularly if you don’t have a pump) when you install the hose.

3. Pumping Waste

Prepare by donning your rubber gloves and opening your blackwater tank. When you turn on the waste pump/macerator, the waste should drain into the tank automatically. As soon as you’re finished, cut off the water supply and connect and open your greywater tank. Repetition of the procedure is required. Last but not least, connect a fresh water supply and run it through the process to clear out the tanks and hoses of debris. The cleanout pipe is the ideal alternative for dumping; but, if you do not have one, you can utilize an access port instead.

Alternative Option: Septic Tank Access Port

If the cleanout pipe is not an option, you can use an access port instead, which is the same procedure as using the cleanout pipe. The septic tank may be reached immediately through the access port. You must remove the access port’s cover in order to use it (but be careful- the gasses that are emitted are DANGEROUS). Examine your dumping location to ensure that you are dumping on the side of the baffle that prevents sediments from entering the septic tank. Dumping on the incorrect side of the fence might cause a serious problem and a leak.

When using either method, make careful to double-check your connections to prevent leaks!

Installing Waste Dump Into An Existing Septic System

Building a permanent dump system from your RV to a septic tank may be time-consuming and expensive. If you often camp on your property (or have visitors that camp on your land), this may be a better option for you than the previous one. One of the most serious possible drawbacks with this approach is that enabling access to your septic tank may harm the environment of the tank by allowing oxygen to enter. This is one of the most common problems with this method. Before trying this, consult with the manufacturer of your septic tank.

Every 100 feet, lower the line by a half-inch to get the desired effect.

You may hire a professional to professionally install an RV dump into your septic system. However, you must first investigate the legality of the situation and choose a trustworthy business, ideally the same one that installed and/or maintained your septic tank in the first place.

Additional tips

If you want to be able to tell when your tanks are clean, you may incorporate an elbow feature (because it is a clear piece of pipe). If you plan on routinely dumping your RV into your septic system, make sure to schedule maintenance (especially tank emptying) on a more frequent basis as a result. In order to get a better understanding of the volume of your septic tank and if you are filling it up to capacity, it is necessary to know how many gallons it can contain. In addition, you should wait until your RV tanks are at least half filled before dumping them.

Why Use A Septic TankDumping An RV?

The most significant advantage of having a septic tank to dispose of RV waste is ease. Those who are not staying at a campground and do not have access to a community dumping location might consider this option. The ideal approach to use if you are camping on someone else’s land (or if you are hosting someone who is camping on your property). It is also less complicated to dump RV garbage straight into a septic system rather than attempting to dump RV waste into your interior house plumbing.

When you shouldn’t use a septic tank to dump RV or camper tank

As previously stated, if you utilize chemicals in your RV, you will have difficulties putting them into a septic tank. You should also avoid dumping in a septic tank if doing so is against the law in your region (see “legal problems”). Additionally, there are several instances in which dumping into a sewer system is not an appropriate solution. If you have to dump your RV on a frequent basis, this can put a strain on your septic system, causing it to become clogged and leaky. If you have a septic tank that is too tiny, you may also experience this problem.

Alternative Options To Dumping In A Septic System

If you are unable to dispose of your RV waste in a septic tank, there are alternative solutions available to you.

Holding Tank Dump Station

Using a dump station at a campground is one of the most effective and practical methods of disposing of waste. You won’t have to be concerned about any problems or potential compromises to your home system as a result of this. If you do this at a campsite, you are not required to refrain from using any chemicals. Another alternative is to find a dumping station that is close to you (or that is near where you will be camping). If your campsite does not have a dump station, or if you are not staying in a campground, this is an excellent option.

Dump Into A Municipal Sewer

You may also dump into a public sewer or straight into your toilet using a bucket, tote, and/or the macerator technique, or you can use a combination of the two methods (grinding and pumping through a hose directly into the toilet). Macerators are a sort of grinder that can be put in a bathroom and that breaks down waste so that it may be flushed down the toilet after being broken down.

This procedure is only effective if you have a limited volume of wastewater to deal with. Putting garbage down the toilet of a home that is equipped with a septic tank will still need you to avoid the use of chemicals.

Dumping Into A Residential Sewer

Dumping into a home sewage system is done in the same way that dumping into a septic tank is done. You will utilize the “cleanout” pipe on your property that connects to the municipal sewer system. The advantages of using this option are that you will not have to worry about chemicals as much as you would with the other options (like with a septic tank). Please keep in mind that you must verify your local laws before proceeding with this operation.

Added Tips And Suggested Items

It’s vital to emphasize once more that if you’re dumping into your septic system, you may need to have it emptied more regularly than usual. In the case of a blocked or overused septic tank, you may notice an unpleasant smell, sewage backing up pipes, water pooling, or spongy grass/moss in the vicinity of the tank and drain field. If your RV does not come equipped with a macerator pump, you may want to consider purchasing one to make dumping more convenient (this is helpful regardless of where or how you dump).

  • TheFlojetis a nice alternative, as is this pump fromShurflois, which is somewhat less expensive.
  • The use of clear elbow pipe connections may be beneficial in recognizing when your tanks are empty and when they are clean, as previously discussed.
  • Here’s a low-cost alternative.
  • Take into consideration choosing a long, thick hose, which will be more durable and will provide you with greater versatility.
  • In addition, sewer hose supports are a smart idea for keeping your hose in position and going downhill.
  • If you aren’t planning on using any of the direct connection techniques, this is a decent backup plan.

Final Thought

Septic systems are one of the numerous alternatives available for disposing of RV waste, and it is one of the dirtiest jobs you can do. Septic systems may be quite useful, especially if you are not staying in a campsite that has an on-site disposal facility. Also suitable if you do not have access to a municipal sewage system, such as in rural areas. When deciding whether or not to use a septic system, there are various considerations to consider. You’ll need to research the rules in your state and town, determine whether or not you’re utilizing septic-friendly chemicals, and locate the location of your septic tank.

Despite the fact that disposing of RV garbage is one of the most unpleasant aspects of RV ownership, there are several solutions for making this process as quick and effective as possible, allowing you to have the finest camping experience possible! The most recent update was made on by

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.

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.

One of the most significant achievements of human civilization has been the decrease of disease transmission through human waste through the practice of hygiene and sanitation, which can involve the use of a wide range of diverse technologies. Wikipedia

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.

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.

How To Dump RV Tanks At Home (The Right Way)

It is necessary to dispose of wastewater in a safe and responsible manner when on an RV vacation because the typical person consumes around 88 gallons of water per day while on the road. In addition to collecting filthy water from the kitchen sink and shower (grey water tank), the holding tanks aboard collect sewage waste from the toilet (black water tank). Those who own recreational vehicles must empty both tanks on a regular basis to minimize overspill and the associated mess. How to dump RV tanks at home without harming the environment or incurring a fine is covered in this section of the guide.

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.

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.

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

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

  • Following these procedures will allow you to dump the tanks in your RV using the bucket technique.

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.

How Often Should You Dump the RV Black Water Tank?

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.

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.

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.

It is not need to worry about the composition of dish soaps, shampoos, cleaning goods, and toilet paper while using them in a standard sewer system.

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

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?

You can use any of the four most common methods listed below to complete the task of emptying the wastewater tanks in your recreational vehicle. Two of them may necessitate the acquisition of specialized equipment. Another thing you will only require is a bucket. Possibly a clothespin, or a dab of Vicks Vapor Rub for your nose, to be more specific. Here are the four most common methods for emptying the holding tanks of your RV at your residence:

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

When it comes to sewage treatment, the macerator technique can be the most difficult, but it is also the most effective for people who do not have a septic system but still want to be able to empty out the entire tank at home. When you use this approach, everything in your tank will be ground up and converted into sludge, thanks to the use of a tool known as a macerator. The sludge will then be funneled into your toilet with the help of a garden hose. This procedure does necessitate the acquisition of a small amount of specialty equipment.

Items that are required:

  • 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.

  1. 6.Always be prepared to flush the toilet as frequently as necessary.
  2. It is at this point that the transparent adapter is beneficial.
  3. 9.
  4. 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.
