Can you hook up your RV to a Septic Tank?

Many people who own both an RV and a septic tank are unsure as to whether or not they may utilize the two together. The RV is the ideal spot to accommodate visitors while yet providing them with their own space. You may connect your RV to your septic tank, but you must do so in the proper manner. First and foremost, it is necessary to comprehend the operation of a septic tank before discussing how you might link the two.

How do Septic Tanks Work?

Sewer septic tanks are divided into two sections, each of which filters through wastewater while separating it from the liquid. As the wastewater is broken down by the natural bacteria in the septic tank, it is spread into the soil, where it sinks and is filtered by the soil. Septic tanks must maintain a precise equilibrium between bacteria and wastewater in order to function effectively. Cleaning products, toilet wipes, and even coffee grinds have the potential to be harmful. It is possible to extend the life of your septic tank by ensuring that you are not dumping excessive volumes of these.

How to Connect to your Septic Tank

Generally speaking, you will find that a clean out is the most convenient method of connecting your RV to your septic tank. This will be a PVC pipe that emerges from the earth and has a screw cap on the end of it. Simple removal of the lid will allow you to connect the sewage line from your RV to this clean out port. Check to be that the hose is well fastened to the pipe opening; you may need to weigh it down to prevent a sloppy mess from forming. You have the option of leaving this connected all of the time so that any wastewater automatically drains into the septic system, or you may choose to wait and empty the tank all at once if you prefer.

Because septic tanks function by utilizing natural bacteria to break down wastewater, it is critical to maintain proper balances in the system.

However, doing so is perilous since exposure to too much air can destroy the naturally occurring bacteria in the tank, as well as the gas contained within the tank, which can be harmful to people.

If you can, dump into the side that separates the solids from the wastewater, or into the side that is nearest to the home, whichever is the case.

Keeping your Septic Tank Working Well

When you connect your RV to your septic tank, you’ll need to take a few extra steps to ensure that the system continues to function properly. Make sure you’re not putting too many more chemicals down your pipes; even goods marketed as septic tank cleansers might deplete the natural bacteria levels in your system. These will only provide a temporary improvement in the overall cleanliness of the system. Make sure you don’t overburden the system with too many requests. As wastewater is introduced into the system, it is forced out through the outlet.

When using the RV plumbing system on a regular basis, be prepared to have the system cleaned more regularly.

If you need more room and solitude, renting an RV as a guest home is a fantastic alternative.

By ensuring that your RV is properly connected and that you are not overloading your system, you may gain more living space while also keeping your septic tank in good operating order. Posts from the recent past

How to Hook Up an RV Sewer Hose to a Septic Tank

In the United States, a recreational vehicle (sometimes known as an RV) is a movable lodging that provides ordinary home comforts and amenities, such as kitchen and bathroom facilities. This implies that an RV also transports a sewage system, which collects and retains all of the waste items generated. So, what is the best way to dispose of the waste material? RV owners no longer physically dump wastewater into bodies of water or even bury waste in the ground, as was the case in previous generations.

Yes, you read that correctly.

You don’t have to be an outdoor enthusiast or an RV owner to understand how and why an RV hose is critical to the overall operation of the vehicle.

What Is an RV Sewer Hose?

An RV sewage system, without a doubt, is critical in the maintenance of an RV’s operations in order to provide a pleasant ride. When you’re all fired up for that camping trip, the last thing you want is to have a fecal issue on your hands. A sewer hose, on the other hand, is required by the sewer system. An RV sewage hose is comprised of a long, ridged, plastic tube that expands and contracts when waste material is flushed out of the RV during its operation. Yes, the septic tank will be linked to the RV hose; this is the one that will be maintained by the local authorities.

The wastewater tank, commonly referred to as a black water tank, is the most important component of an RV’s sewer system.

Owners of recreational vehicles (RVs) may avoid unforeseen disasters by learning how their tanks work and why waste material removal is necessary for their vehicle.

RV Sewer Hose makes cleaning easy

The use of an RV hose makes cleaning the tank much easier, which is especially important given the fact that it must be cleaned on a regular basis. Don’t put off cleaning your RV’s tank since accumulated wastewater can cause serious difficulties with the vehicle’s operation. This not only assists you in maintaining better hygiene, but it also helps to ensure that your RV does not smell. With the purchase of an underground wastewater collection system (sewer hose), you not only get the hose but also various extra attachments such as hose fittings and valves, which make the septic tank connection process a whole lot easier.

A tiny trickle of water might quickly turn into a fatty, filthy puddle.

Connecting the RV to a Septic Tank

In order to begin, determine the amount of wastewater currently present in the RV tank. Generally speaking, the tank must be two-thirds full in order to provide the ideal pressure necessary for waste to be flushed out. The most critical step after that is to identify the output valve of the RV that is necessary. Before connecting the sewage line to the wastewater tank, make a note of the valves on the tank. If the sewage hose is attached to the water input valve, you must proceed with greater caution during this phase.

These septic tanks, which are also referred to as “dump stations,” are managed by the local council or government and are typically intended for this single function; thus, checking the accessibility of a dump station would be beneficial as well.

Once the sewage hose has been connected between the RV and the septic tank, open the wastewater tank and turn on the RV’s pump to complete the process. Although it is typical to find these pumps in RVs, if there isn’t one operating, you may need to purchase one to make up for lost time.

Do you need a macerator pump?

This type of pump is referred to as a macerator pump, and it has the job of grinding up the waste items that accumulate in the black tank. Essentially, macerator pumps help to increase the flow of waste water from the sewage system to the septic tank. If you are utilizing an external macerator pump, be sure that the sewage hose is connected to both the pump and the septic tank at the same time. You only need to make sure that the disposal is running properly with an external or internal pump.

  1. Upon completion of the emptying of the tank, the pump and tank valve can be restored to their original positions.
  2. Once again, it is critical that the valves are correctly linked since we do not want a leaking connection in the pipeline system.
  3. Using this method, you will be able to watch the flow of sewage and afterwards validate its purity.
  4. In the long term, it ensures not only the cleanliness of the RV’s sewer system, but also the preservation and sanitization of the tanks.
  5. You don’t want to end up with a literal and muddy disaster on your hands.
  6. Recommended Pump for RV Macerator

You’ve just returned from a long journey, and all you want to do now is rest. For the sake of maintaining harmony, you put up your travel trailer for your visitors while they were here to visit. The in-laws are staying on your property for a couple of months in their RV, which they brought with them. It doesn’t matter what circumstance you’re in; the same concern surfaces. The holding tanks on the bus need to be drained as soon as possible. While you have a septic tank in your yard, you’re not sure what it will do to your drainage system.

Is It Okay To Dump Your RV Waste Into Your Home Septic System?

The quick answer is that sure, it is possible. It is OK to discharge your RV waste into your septic system. Commercial-sized septic systems are actually installed on the grounds of a number of campers. It is not necessary to replace your RV’s holding tank as long as you make simple modifications to your holding tank maintenance schedule.

Before you connect your RV to the electrical grid, you need understand how it works and what to look out for. RV holding tanks function in a different way than residential septic systems. Here are some considerations to bear in mind.

How Your Home Septic System Works

Answer: Yes, in the simplest form. Dumping RV waste into your septic system is perfectly acceptable under most circumstances. Commercial-sized septic systems are actually installed on the grounds of a lot of campers. It is not necessary to replace your RV’s holding tank as long as you make simple modifications to your holding tank upkeep. Be familiar with the operation of your RV’s system and be aware of any potential hazards before connecting it. Unlike house septic systems, RV holding tanks operate in a different way.

Things To Be Aware Of

If properly maintained, a septic tank can survive for several decades. Pumping the tank every three to five years will keep sludge from accumulating in the tank. Otherwise, it is possible to have a maintenance-free system. Dumping the contents of your RV into your septic system might throw the system’s delicate balance out of whack. A single draining of your holding tanks is not as significant as a series of drainings on a regular basis. It is just as important to be mindful of what you are dumping as it is to be mindful of how often you are dumping.

Connect to the Septic Cleanout Pipe Correctly

Every septic system is equipped with a cleanout pipe that protrudes from the ground. Some of the more recent systems employ a white PVC pipe that is located near to the home itself. It’s only a matter of getting the correct length and fitting for your RV’s sewage hose to connect to this pipe. If the sewer hose from your RV does not fit through the cleanout pipe, sewer fittings can be purchased to fasten it. Storm drains should never be used to empty your tanks. First and foremost, it is against the law.

Putting tainted water into these drainage systems may result in severe fines if done intentionally.

Protect the Septic Tank Bacteria

Formaldehyde is included in some of the chemicals used in RV toilets to decompose waste and deodorize. In most cases, they are blue in hue. When it comes to microorganisms in your house septic tank, this chemical is toxic. The bacteria in your septic system must survive in order for it to function properly. Professional septic system professionals are the only ones who can restore normal operation to the system. It may take several weeks or months to bring the bacteria count back to a healthy level after an infection.

  • Septic system-safe tank treatments are being developed by RV toilet chemical producers.
  • Look for remedies that are both effective and safe to use.
  • Use premeasured pods or dry items instead of liquids.
  • Aerobic bacteria are used in bioactive goods, which means they may continue to operate after being drained.

These varied goods are environmentally friendly in their design. Because they are non-toxic to people, you don’t have to worry about being exposed to them if you spill them. The other advantage is that your septic system is capable of dealing with these treatments without issue.

Monitor Flow

The pipes that connect the septic tank to the drainage field are experiencing a mild deterioration. This allows the water to pass through and push the solids out. If the angle is sufficiently high, the water will skip the solid substance and flow directly through it. Make sure you don’t overburden your septic system when you empty the holding tanks of your recreational vehicle. Septic systems have a certain water-to-solids ratio that must be maintained. In order to keep the flow of waste water into your septic system under control while draining full tanks, it’s a good idea to only open your tanks halfway.

If you are experiencing low flow concerns, you should try an acerator pump.

They generate flow while also churning up solid debris in large quantities.

The output may be connected to either a sewage hose or a standard garden hose.

Adjust Your Septic Pumping Schedule

If you are regularly emptying your holding tanks into your septic system, you are effectively expanding your living space. It is possible that your septic system will need to be cleaned sooner than anticipated. Pumpings are performed on a regular basis every three to five years. The majority of individuals who have septic systems hire a company to keep their system in good working order. This service firm comes out every few years to pump out the septic tank, which is maintained by the homeowner.

It is always advisable to contact your septic service contractor for advice.

They can change your pumping schedule so that they come out more frequently to pump out your tank as needed.

Alternatives to Dumping Your Tanks At Home

If you do not have a septic system, several septic service cleaning companies offer “Honey Wagon” vans that can clean your septic system. When they go out to empty a house septic tank, they pump the contents of the tank onto a truck that they have brought with them. Some of these service companies will come to you in order to empty your recreational vehicle. It’s still a pretty new service, so bear with me. This is not a service provided by all septic providers. This is a service that larger campsites, such as KOA, provide to its customers.

Travel Centers

Pilot/Flying RVs are catered to by J, Love’s, and TA Travel Centers of America. Many of them feature specific RV lanes and services. They provide holding tank dumping services at the pump for your convenience. These services are not free, however their pricing are in the range of $10 to $15 per hour. Their rewards programs provide discounts to anyone who join up to participate. Some RV discount clubs also partner with these service centers to provide savings to their members.

Install Home RV Sewer Dump on Septic System

The most recent update was made on October 9th, 2019 at 01:48 p.m. If you keep your RV at your residence, having the ability to empty your RV holding tanks at your residence is a tremendous benefit. It is possible that you will wish to install an RV sewer dump on your house sewer line. Nonetheless, if your house is equipped with a septic system, you should have a thorough grasp of how it operates before adding an RV sewer dump to the mix. If this is not done correctly, it may result in the need for costly repairs to your septic drain field.

  1. The most important thing to remember is that sewage lines should not have sudden reductions in pressure since the water will leave sediments behind, causing them to accumulate in the drain pipe.
  2. One inch of drop in a one hundred foot line is nearly too much; you should aim for no more than a half-inch drop per hundred feet at the very maximum.
  3. NEVER connect your RV’s dump line to the drain field; instead, connect it to the septic system between the home and the septic tank.
  4. Other options include draining your RV dump directly into the top of your septic tank, preferably before the baffle if your tank has one, but after the baffle will work if that is the only alternative available.
  5. The baffle in a septic tank guarantees that sediments do not pass across the top of the liquid and out into the drain pipes, but rather that they do flow down.
  6. I usually make sure that the dump is about six inches below the surface of the water.
  7. When establishing new septic systems on properties large enough to accommodate RV parking, I always offered to add a free RV dump, which I connected between the house and the tank whenever practical.

I reasoned that installing one now would spare me the trouble of digging up the yard later, and the additional cost of the pipe was little.

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!

This is not only unclean, but it may also lead to the transmission of serious infections and the failure of your RV’s plumbing system.

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.

  • 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.
  • 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.
  • 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.
  • Septic tanks, on the other hand, only need to be emptied every few years (depending on the system).
  • 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.
  • 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. Fines can be as high as $1,000, so be on the lookout for them!

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

Before you can empty your RV tanks into a septic tank, you’ll need to acquire a few additional items. In addition to gloves, a hose and a waste pump will be essential tools for the job. A pump is not absolutely necessary, although it is better in many situations. You could also consider purchasing a transparent elbow pipe adapter. Having a water supply nearby (such as a garden hose) is beneficial since it allows you to flush out the system after you’re through.

2. Finding The Cleanout Pipe And Attaching Your RV Tanks

In order to dispose of your RV tanks in a septic tank, you’ll need to acquire certain items first. In addition to gloves, a hose and a waste pump will be essential tools for this job. Although a pump is not absolutely necessary, it is recommended in most situations. A transparent elbow pipe attachment may also be required. To ensure that the system is completely flushed out once you’re through, it’s helpful to have a water supply (such as a garden 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.

Also, avoid leaving the hose connected and the lid open for an extended period of time, since this might harm the environment in the tank by allowing in an excessive amount of oxygen. 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.

Additional tips

A permanent dump system from your RV to a sewer system is time-consuming and expensive to install. When it comes to camping (or having visitors who camp), this option may be preferable for those who camp on a regular basis. This approach has a number of possible drawbacks, one of which is that granting access to your septic tank may harm the environment of the tank by allowing oxygen to enter it. Before trying this, check with the manufacturer of your septic tank. Elevation and drop are two other factors to consider.

This will aid in preventing a clogging of the system.

It is necessary, however, to 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.

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. On your property, you will connect to the municipal sewer system through a conduit known as a “cleanout pipe.” The advantages of this approach are that you don’t have to be concerned about chemicals as much as you would otherwise (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).

  1. TheFlojetis a nice alternative, as is this pump fromShurflois, which is somewhat less expensive.
  2. 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.
  3. Here’s a low-cost alternative.
  4. Take into consideration choosing a long, thick hose, which will be more durable and will provide you with greater versatility.
  5. In addition, sewer hose supports are a smart idea for keeping your hose in position and going downhill.

Alternatively, if you must transport your RV trash in a tote, you may purchase a heavy-duty tote such as this one from Amazon. If you aren’t planning on using any of the direct connection techniques, this is a decent backup plan.

Gray water

Water from sink and tub/shower drains may include food particles and other microorganisms that are harmful to human health. As much residue as possible from dirty dishes is caught in the sink drains, in an effort to maintain the sink drains as clean as possible. Dishes are scraped thoroughly, and the drain trap is used to capture the majority of the remaining particles that might cause blockages in the future. Some RVers, on the other hand, are far less cautious. The RV has two holding tanks, one for gray water and the other for black water, both of which are accessible from the bottom of the vehicle.

It is possible to quietly (and legally) remove small volumes of gray water directly on the ground when camping or boondocking in rural places, depending on where you are camping or boondocking in remote locations.

Please bear on mind that we leave the gray tank open until a couple of days before we are due to leave a campsite. For more information, continue reading. Although it may seem unpleasant, dealing with septic tanks is not as as unpleasant as it may appear at first glance.

how often to empty RV holding tanks

The frequency with which you must empty your black tank will vary depending on how frequently you use it. For us, it usually comes down to 1-2 times a week. Several RVs are fitted with digital sensors that may be used to monitor the levels of water in your freshwater, graywater, and blackwater tanks, among other things. Unfortunately, you can’t always rely on them since the black water contents of the tanks frequently become trapped on the edge of the tanks, causing the sensors to malfunction.

how to prevent rv septic clogs

Make Use of Enough Water To assist avoid toilet clogs, make sure that the toilet bowl has a proper quantity of water before flushing it. It also doesn’t hurt to be frugal with your toilet paper usage. Make use of Liquid Fabric Softener. We use the tank rinser every time we empty the black tank on the day we leave the campsite, which is about once a week. Beyond that, we periodically pour a tiny quantity of liquid fabric softener into our tank through the toilet, which makes the contents of our tank more slippery, which helps to remove any contents that become caught on the edges of the black tank.

Take Advantage of the Movement of Travel Days to Your Advantage Before leaving, you may add some water to the black tank and let it to splash around inside the tank, breaking up any solid waste that has become lodged.

STORing your rv septic supplies

We keep all of the sewage materials (hoses, fittings, tank rinser and backfill hose, and so on) in a storage container in one of the compartments, which is accessible from the rest of the compartment. Our storage containers are manufactured by Sterilite, and we purchased them from Walmart. We have a container for freshwater products and a second container for materials for the black tank. Do not keep them together in the same place! The size of the storage boxes you pick will be heavily influenced by the number of storage compartments you have, so be careful to measure the available space before buying.

However, you should avoid flushing the toilet while the fan is operating.

Yes, we had to learn that lesson the hard way straight away, soon after we started.

This is the quickest and most convenient method. In contrast, other campsites (such as state parks) may just provide water and electricity. Check websites or phone beforehand to make sure what you want is still available. A large number of campgrounds feature on-site wastewater disposal facilities.

how to empty the rv septic tanks


  1. The day before you want to empty your black tank, close the grey tank valve. When you’re ready to empty the bathroom, ensure sure the fan is turned off.

*Keep in mind that when you are backfilling your black tank, you should keep an eye on the water level. A timer or having a spouse monitor the level from the inside have been suggested by various RVers I’ve spoken with about. I wouldn’t base my decision on the RV sensors. Since purchasing our camper, ours has been inconsistent at best. It has been brought to my attention that some tourists have had disastrous results after leaving their campers unattended throughout this process.** Bonus tip: Close the gray tank valve a couple of days or so before you plan to empty your black tank to give the gray tank enough time to fill up before you empty your black tank.

However, while it is not a substitute for consistently cleaning your black tank, it does assist to reduce the odor.

How To Hook Up An RV Sewer Hose And Use It (5 Simple Steps)

When you have to empty those dreadful black and gray tanks at some point during your RV journey, the excitement will come to a screeching end (if only momentarily). While it is true that connecting your sewer line and draining your tanks may take some time, it will not be as dirty as you would think! Here is our easy 5-step procedure for connecting your RV sewage hose, draining your tanks, and getting back to enjoying the RV lifestyle as soon as possible!

Step 1: Preparation

Making the necessary preparations to empty the black and gray tanks is not something you should take lightly. Not only can it be disgusting, but it may also be harmful to your health in some cases. As a result, you should dress in disposable gloves and eye protection to ensure that you are as prepared as possible for what lies ahead. Also, this is an excellent opportunity to double-check that the valves on your sewer pipe are properly closed.

Step 2: Connect The RV Sewer Hose

Following your preparation for the work, it’s time to connect the sewage hose to your recreational vehicle (RV). This hose will have two fittings on either end: one with a bayonet-style connection that connects to your RV, and the other with an elbow or “L” shaped fitting that connects to the dump station inlet. To begin, attach the bayonet type fitting to the waste fitting on the RV’s waste tank. Then connect the other end of the hose to the dump station inlet, ensuring that the elbow fitting is properly positioned within the inlet.

Using this method, you will be able to make a tight seal and avoid any leaks (and believe us, you do not want any leaks).

This is especially beneficial for places where the terrain slopes upwards toward the dumping sewer outlet.

Step 3: Drain The Black And Gray Tanks

The sewer hose should be connected to your RV once you’ve completed your preparations. This hose will have two fittings on either end: one with a bayonet-style connection that connects to your RV and the other with an elbow or “L”-shaped fitting that connects to the dump station inlet. In order to begin, attach the bayonet type fitting to the waste fitting on the RV. Then connect the other end of the hose to the dump station inlet, ensuring that the elbow fitting is properly positioned in the intake port.

Using this method, you will be able to make a tight seal and avoid any leaks (believe us, you do not want any leaks!).

Use an RV sewer hose support to aid in the creation of a downhill effect for your hose and hose fitting. If the earth slopes uphill to the dumping sewage entrance, this will be beneficial for such places.

Step 4: Disconnect The Hose

To disconnect the hose from the RV, twist the end of the hose that is attached to it, and then replace the cover on the waste valve. IMPORTANT: Do not disconnect the hose from the input of the dump station until the job is finished. We still need to wipe out the hose, and we want the water to drain down into the intake. Then we’ll get to the point. Having completed your successful tank emptying mission, it is now time to clean up!

Step 5: Cleanup

Last but not least, we must clean out the sewer hose and save it for use in the future. Maintaining connection to the waste station inlet with a sewage line, spray out the inside of the dump station with a garden hose to enable water to pass through the hose and into the inlet. A sewage hose rinser with a bayonet cap may be used to quickly and conveniently clean up your sewer hose! It will save you a great deal of time and effort. Once the interior of the hose has been thoroughly cleaned, disconnect the hose from the input and thoroughly clean the elbow connector.


Yes, it is feasible to connect your RV sewer line to your home’s sewer system; but, depending on where you reside, this may not be permitted. Before doing anything, be sure you are in compliance with local regulations. If it is legal, it is truly as simple as following the procedures above: simply replace the campsite dump inlet with your house sewage inlet (you’ll have to look for the sewer cap in your yard), and you are done.

How do you hook up two RV sewer hoses?

With two sewage hookups on your RV or motorhome, it is possible to have three sewer lines: one from each hookup to a “Y” connector, one from the “Y” connector to the dump site inlet, and a third hose going from the “Y” connector to the dump site inlet. It’s a really straightforward configuration that just necessitates the installation of two more hoses and a “Y” connector. Camper FAQs is made possible by donations from readers.

Can I Dump My RV Waste Water into House Septic Systems?

If you’re an RVer who lives in a rural area, you might ask if it’s okay to dump RV waste water into your home’s septic system. The answer is yes. Why not simply connect a line from your truck to your home septic tank and accommodate visiting visitors in that manner? Is it even feasible to do this? The short and easy answer to this question is yes. Yes, it is possible to put RV waste water into residential septic tanks.

This “yes,” on the other hand, comes with a great deal of responsibility. If you look closely at this statement, there are several ifs, buts, ands that are included in it. If you educate yourself, you will be able to use your home’s septic tank to empty the black and gray water tanks of your RV.

The Right and Wrong Way to Dump RV Water Tanks into House Septic Systems

If you want to discharge RV waste water into residential septic systems, you should be familiar with the fundamental functioning of a normal home septic tank system.

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.

  • Waste and water are transported via pipes after every flush or every time the faucet is turned on or off. Waste is expelled from the home and dumped into the septic tank. A baffle in the center of the tank prevents sludge, grease, and oil from exiting the tank and causing obstructions
  • The baffle has an entrance in the middle of its length. This makes it possible for wastewater to pass. Also stops oil at the top of the tank from draining into the drain field because it prevents particles from settling at the bottom of the tank.

Waste is put to the tank, and the tank is filled with water, which is pushed out to the drain field in proportion. The drain field is comprised of three perforated pipes, which are referred to as laterals. One-quarter inch each foot of pipe length results in the pipes sinking deeper into the earth. A rapid descent is not advantageous since the water would not force solids forward, but would instead slip straight past them. The subterranean pipes are bordered by pebbles, which helps to ensure that drainage is smooth and straightforward.

Because of the description provided, you must be aware of the exact location of your septic tank underground in order to avoid dumping on the incorrect side of the baffle.

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

Having gained a thorough grasp of how a septic system operates, we may determine that the most convenient approach to empty your tank is through the septic system’s cleanout. An example of an above-ground PVC pipe with a screw cap is shown here. This may be located between the house and the tank on the property’s grounds. Simply remove the cleanout’s lid and connect your sewage hose to both your RV and the cleanout, then close the cleanout. Make sure to place something heavy on top of the hose if you are unable to tie it to the pipe opening.

  • In either case, you have two options: either keep your RV connected up and allow sewage to slowly seep into the septic system, or hold off and empty the black water tank in one go when you’re ready to dump it all at once.
  • Some claim that it shocks the system and causes the normal microorganisms to become disrupted.
  • Sludge and other solid particles may spill over the baffle and into the outflow as a result of this condition.
  • Check out this article on how to properly dispose of RV waste tanks.

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.

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!
