How To Add Camper To Septic Tank? (Solution)

How to Connect to your Septic Tank. Typically, you will find a clean out is the easiest way to connect your RV to your septic tank. This will be a PVC pipe that comes out from the ground with a screw cap. You can simply remove the cap and attach the sewer hose from your RV into this clean out.

  • Attach your waste pump to your RV, then connect a hose which will attach or flow into the septic tank cleanout pipe. You can unscrew the cap and hook up your RV sewer hose to this pipe. If the hose can’t be securely attached to the cleanout pipe, use something heavy to put pressure (and prevent the hose from coming loose in the process).

Can I empty my RV into my septic tank?

How does RV septic work?

A camper septic system works by simply acting as a holding tank for your sewage. It’s not a SEPTIC TANK that works like at a house. With an RV septic system there are no leach fields, no breaking down needed (not really), none of that. It holds your sewage until you dump it.

How do I plug my 30 amp RV into my house?

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.

How Your Home Septic System Works

Material is filtered out of your septic system before it is discharged into the drainage field. The baffle is the first of several filters. It removes oils, sludge, and other contaminants that might clog the system’s flow and cause it to malfunction. The septic tank is divided into two chambers by a wall that is evenly spaced apart. There is a little aperture about halfway down that permits water to pass through. On the other side are a series of pipes via which water and sediments are channeled into a drainage system.

  1. Solids are forced through the drainage field as a result of this pressure.
  2. Their primary function is to decompose waste materials.
  3. Certain home pollutants can be hazardous to these microorganisms, and they should be avoided.
  4. It might take months to complete the breakdown of the raw elements.
  5. Having your sewage system pumped out every few years also helps to keep sludge from building up and overflowing the tank.
  6. Another consideration is the amount of rooms in the residence.
  7. This value is a general estimate of the amount of waste that the septic tank can manage.

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.

  1. Septic system-safe tank treatments are being developed by RV toilet chemical producers.
  2. Look for remedies that are both effective and safe to use.
  3. Use premeasured pods or dry items instead of liquids.
  4. Aerobic bacteria are used in bioactive goods, which means they may continue to operate after being drained.
  5. Because they are non-toxic to people, you don’t have to worry about being exposed to them if you spill them.

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.

They will attach themselves near your holding tanks. The output may be connected to either a sewage hose or a standard garden hose. These electric pumps are also capable of cleaning up the build-up that has accumulated in your tanks.

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.

How Your Septic System Works

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.

  • 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.

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

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 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.

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. Most recreational vehicles are equipped with a sensor, or one may be fitted, that indicates how full the tanks are.

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

A home sewer system is operated in the same way that a septic tank system is operated. On your land, you will connect to the municipal sewer system through the “cleanout” pipe.

This method has the advantage of reducing the amount of time you have to spend worrying about chemical exposure (like with a septic tank). Please keep in mind that you must verify your local regulations before proceeding with this process.

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!

How to Construct a Small RV Septic System

In order to construct an RV septic system, a scaled-down version (or replica) of an existing full-size system must be built. A smaller septic system will suffice for an RV because to the lower volume of waste generated compared to a septic system designed for a house. You may put up a basic but effective system using items from your local hardware store, plumbing supply store, and stone yard, among other places. Check with your local zoning authority to see if any permissions are necessary.

Step 1

To do this, locate the main sewer line that comes from the RV.

Step 2

An 8- to 10-foot section of PVC pipe should be connected to the RV’s main plumbing pipe. (Optional) If the pipe is to be used horizontally, it should be fastened using a clamp that may be quickly removed when traveling by RV.

Step 3

The distance between the entrance hole and the bottom of the tank should be measured. This measurement must be taken from the bottom of the pipe and must be the depth of the hole.

Step 4

Make a hole in the ground and place the tank in it according to your specifications. This is the septic tank, which is responsible for separating solid waste from liquid waste.

Step 5

Using your fingers, gently press the intake from the RV drain into the tank until it is tight.

Step 6

Backfill the ground surrounding the tank once it has been levelled.

Step 7

Attach an elbow to the end of the drainpipe that is pointing down and toward the bottom of the tank with hot glue.

Step 8

Pitch down 1/8 inch each foot for a 10-foot ditch from the tank’s outlet hole to the end of the tank’s outlet pipe.

Step 9

Install PVC pipe from the outlet hole to the far end of the trench, following the manufacturer’s instructions.

Step 10

Glue a PVC elbow to the outflow pipe in the tank, with the elbow pointing down and toward the tank’s bottom.

Step 11

A PVC elbow should be attached to the tank’s exit pipe so that it points downward and toward the tank’s floor.

Step 12

Fill up the hole with stones. Fill the hole with water until it reaches the bottom of the pipe.

Step 13

In addition to the PVC solid pipe, a 2-foot piece of 4-inch PVC perforated pipe should be used as an extension.

The perforated pipe should come to a stop in the middle of the stone-filled pit and slope downward at a rate of 1/8 inch every foot of distance.

Step 14

Stones should be used to cover the perforated pipe. Ideally, stones should be placed around the pipe and at least 4 inches above the pipe’s surface.

Step 15

Apply rosin paper on the stones to help remove the dirt from the stones and keep them clean. Once the earth has been compacted, the rosin paper will gradually disintegrate, and the dirt will no longer mix with the stones.

Step 16

Replace the tank’s lid on top of the tank.

Step 17

Then, replace the tank’s lid on top of it.

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.

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!

Adding an RV dump to my septic system

JCasperHillsboro, ORSenior MemberJoined: 05/09/2007View ProfileOffline

I’m not sure where I should post this.I live on 5 acres and have a fully functioning septic system.It is 30 years old, but checked out well, has a 1,000 gallon concrete tank and 4 lines each 110′ long.I would like to add an RV dump to this for friends that come to stay and also for the occasional time when I get home without finding a dump station.The area where I want to add this is about 30-40′ higher in elevation then the septic tank and about 100′ away.What is the proper way to do this.I’m assuming I just run 4″ ABS to a tee in the inlet line before the septic tank.What else needs done so I don’t have any problems.I just did a huge renovation to this house and definitely do not want to create any problems, I want it done right.Thanks for any advice you can give.Joe

My septic is a lot closer to my RV hook-up. I put in everything. Fresh water fauset, 20,30 and 50 amp RV electrical box, and sewer line.My 4 inch ABS has a screw lid. It goes down about a foot in the ground, then over towards the septic. I poured a 12 inch by 12 inch by 4 inch deep concrete pad around the top of the connection for protection against damage. I haven’t had any problems. Our home is connected to one side of the septic and the RV connection on the other side. They have knock out holes to insert the pipe. Once the hole is knocked out and you have inserted the 4 inch ABS you can put a sealer around the pipe to prevent dirt from getting into septic.

So it would probably be better to dig around the septic and find another knock out hole to go into rather then a T in the line.That sounds good to me.I have a 50 amp RV plug on the outside of my garage, the In-Laws requested that when I built the house.There is also a fresh water Faucet next to the plug

That’s what I did, ran a 4″ line T’d into the line going into the septic.Mine runs about 80′, but with only about 4 – 5′ rise.With 30 – 40′ rise you’re going to have some velocity in that line, might want to talk to a plumber on how to handle that.

Not to spoil your idea, but you have to be careful with emptying into your septic system.Mainly, if you allow a large rush of waste into the septic tank, as it would be dumping the RV tanks, you run the risk of pushing solids out of the septic tank and into the leach field.A septic isn’t designed for the sudden flows much larger than the flush of a toilet which is only about three gallons or less at a time.

If you live in a highly regulatory area with nosy neighbors who want to be the “septic police”, might want to check with any local restrictions that may ban the practice, or have strict guidelines that require an inspection to ensure compliance. I am aware of at least one recent situation in TX. where draining RV sewer into septic was prohibited.

One note of caution:Be careful about the kind/amount of chemicals used in the RV’s that you allow to dump in your septic tank. Many of the chemicals folks use containformaldehyde, which is added since it’s deadly to bacteria. And your septic system DEPENDS on bacteria to function properly! A “slug load” of heavily chemicalized waste can stop the system’s biological process, and recovery may take some time- if it recovers at all without being pumped out.* This post wasedited 05/10/12 11:30am by Francesca Knowles *

Input is usually on one end on either side and output is on the other end beyond the baffles.

Easy 17 Steps – How To Build A RV Septic System?

It’s not everyone’s favorite subject, but if you spend a lot of time in an RV, learning how to establish a septic system is essential. Simply put, you won’t be able to convert your RV into a motor home unless you first install a septic system.

Basic Componentsof theRV Septic System

RV septic systems may be as basic or as complex as you want them to be, but they all have some components in common. Most recreational vehicles have at least some of the following features.

  1. Gray water tank– This tank is used to store the liquids that drain from your sink or shower. It does not include any of the waste that is generated by your garbage disposal or bathroom toilet. It is not drinkable, but it may be used to wash your recreational vehicle
  2. All of the waste from your RV’s toilet and all of the waste from your shower and sink are collected in the black water tank, which is also known as the waste water tank. However, the fundamentals remain the same regardless of the arrangement of the dump system from RV to RV. You connect a sewage pipe to the gray or black tanks and empty them into a disposal facility
  3. You clean the tanks.

HowtoClean RV Black Water Tank?

A great deal of trouble with septic systems may be prevented by performing routine maintenance and planning ahead of time.

1. EnzymesandWaste Tank Solutions

The chemical solutions for waste tanks are available to break down the wastes in black water tanks. Whatever they are, active cultures or synthetic, it doesn’t matter as long as they are acceptable for use in recreational vehicles. It is not recommended to use poisonous solutions since they may cause harm to the tank.

2. Clean Your Tanks

There is disagreement about whether to empty the tanks when they are completely filled or when they are 3/4 of the way full. When I’m three quarters of the way through, I like to empty them since letting the tank to build up can be dangerous. When cleaning both tanks, make sure to use gloves at all times. The black water tank should always be cleansed first, followed by the gray water tank. Maintain the health of your RV septic system by flushing, cleaning, and sanitizing it on a regular basis.

HowtoBuildaRV Septic Systemin17 Steps?

You may construct a septic system for your RV by patterning it after a conventional septic system, with the exception that it will be smaller. Before you begin, be sure you are in compliance with all applicable zoning rules and that you have obtained all necessary permissions. What You’ll Need in Terms of Tools and Materials

  • A shovel, paper rosin, a tape measure, pipe adhesive, and perforated PVC pipes are all required.

Step 1

Locate the main sewage pipe for your recreational vehicle.

Step 2

An 8- to 10-foot length of PVC pipe should be connected to the plumbing coming from your RV. Specifically, this is the pipe that extends horizontally and is fastened by a clamp.

Step 3

Calculate the distance between the tank’s bottom and the entrance hole with a tape measure and a ruler. Determine the depth of the hole measured from the pipe’s bottom.

Step 4

Grab a shovel and dig a hole, then position the tank according to the measurements you obtained. Essentially, this will serve as your septic tank, and it will separate liquid waste from solid waste.

Step 5

The entrance from your rig drain should be placed in the tank. Check to see if it is a tight fit.

Step 6

After the tank has been leveled, cover the space surrounding it with earth to conceal the leveling.

Step 7

Obtain an elbow pipe and glue it to the end of the drainpipe. The elbow should be positioned such that it faces down in the direction of the tank’s bottom.

Step 8

Dig a trench 10 feet deep along the length of the tank’s outflow hole at the end. Pitch is approximately 1/8″ per foot.

Step 9

Install a PVC pipe from the outlet hole all the way to the end of the trench.

Step 10

Locate the output pipe and connect a PVC elbow to it with a hose clamp.

The elbow should be positioned such that it points towards the bottom of the tank.

Step 11

Excavate a ten-foot-deep hole at the other end of the trench.

Step 12

Fill the holes with stones, and then fill the hole along the pipe’s bottom with more stones.

Step 13

Remove the solid end of the PVC pipe and insert a 4″ perforated PVC pipe. Make certain that the perforated PVC pipe terminates in the center of the hole that has been filled with rocks. Slope it down at a rate of 1/8 of an inch each foot.

Step 14

Place stones on either side of the perforated pipe. The stones around the pipe must extend four inches above the pipe’s surface.

Step 15

Place rosin paper over the stones to prevent them from becoming mixed with the dirt. After you’ve packed in the earth, the rosin paper will disintegrate, and the dirt will not mix with the stones as it would otherwise.

Step 16

Cover the stones with rosin paper to prevent them from becoming contaminated with the soil and other materials. As soon as you start packing in the earth, the rosin paper will disintegrate and the dirt will not mix with the stones.

Step 17

The final step is to backfill the soil in the trench with dirt.

RV Black Water Tank: 6 Things You Need to Know

Even though this is one of those subjects that no one wants to talk about, if you don’t know how to clean an RV black water tank, you’ll wind up with a huge mess on your hands. In order to live in a mobile home, you will have to confront the realities of waste management and disposal, which are not pleasant. Some RVers do not bother with the black tank, and this is understandable. They just park their RV where there is access to a public restroom. The question becomes, what happens if your RV breaks down in the middle of nowhere?

And who doesn’t prefer the privacy of a private bathroom over the public restroom?

1. Background

The black water tank in an RV functions as a holding tank for everything that is flushed down the toilet while traveling. In addition, most RVs are equipped with a gray water tank, which stores water from the kitchen sink and shower. This water does not include any of the garbage that has accumulated in your RV; it only contains water. It is referred to as a gray tank because the soap residue gives it a gray appearance. Because the black water tank includes both solid and liquid waste, it must be disposed of in a correct manner.

2. Startwith theRight Base

Check to see that there is enough water in the tank as a starting point for your procedure. The water is used for two different purposes. It does two things: first, it inhibits odors from spreading throughout your RV, and second, it keeps solid waste from clinging to the sides and bottoms.

3. RV Black Tank Chemicals

Adding black tank chemicals to the water once it has been obtained can help to minimize the odor even more and prevent trash from clinging to the water. RV black tank chemicals are widely accessible, and they come in a wide range of fragrances and designs to choose from. If the chemical has been developed expressly for use in black water tanks, you may be confident that it is environmentally benign. By pouring the chemical into the tank, it will dissolve the waste and prevent an odor from accumulating in the tank.

According to the product label, the directions for applying the chemical vary from one product to another. The volume varies from bottle to bottle, but a couple of ounces is generally sufficient for 3 to 4 days’ worth of use.

4. Emptying Your RV Black Tank

You can fill your tanks with water and dump them at the station if you’re about to leave the campsite but your tanks aren’t yet completely full. In order to properly dispose of your garbage, look for a campsite or other appropriate area. When you’ve located a dump station, attach your waste hose to the rig and secure the other end to the dump station’s dumping station. You’ll empty both the gray and black water tanks, however the black tank must always be the first to be emptied. Close the black water valve after the tank is completely depleted.

Because the gray tank is not as unclean as the black tank, you must empty the black tank first.

5. RV Black Tank Flushing

Emptying the black water tank on a regular basis is only one piece of the whole maintenance process. You’ll also need to wipe out the black water tank in a more thorough manner than before. The accumulation of tissues and garbage can block your toilet, making regular maintenance a must. There are two different methods for flushing a black water tank. The black tank flush valve is the most commonly seen kind. This is something that almost all RVs have, therefore it’s definitely the best option.

  1. Just flush it down the toilet and you’re done.
  2. If your RV does not come equipped with a flush, you may purchase an aftermarket black valve to replace it.
  3. In most cases, you will just need to drill a tiny hole in the black water tank to accommodate the valve installation.
  4. In order to accomplish this, you’ll need a garden hose extension or an RV tank rinser that can jet water in various directions in the tank to remove tissue and other debris.
  5. Once you’re certain, turn on the RV toilet flush valve and insert the tank rinser so that it enters the black water tank of the vehicle.
  6. Make sure the rinser is turning and twisting so that it can reach all areas of the tank.

6. Portable RV Waste Tanks

If you plan to camp for a lengthy amount of time in an area where there is no sewer connection, a portable RV waste tank will be quite useful. Essentially, these allow you to empty your black and gray water tanks through an external tank, as the name indicates. After you have emptied the tanks, you may dispose of them at a dump station. These tanks are equipped with a handle and wheels for simple movement, allowing you to drag the tank to the station in a matter of minutes.

Even though there are many different types of RV portable waste tanks, they still require the same maintenance, flushing, and cleaning as a standard black water tank. Follow any additional instructions that may be provided.

Additional TipsforRV Septic Management

Make certain that you only use legal disposal stations. There are a few free dump stations that are either badly kept or contain chemicals that are dangerous to your RV hose and tank. Any chemical that contains formaldehyde should not be used since it may cause harm to the tank. Purchase only from trustworthy sources to ensure that the substances you’re purchasing are safe. After you’ve finished using the dump station, make sure to clean up. Remove any remaining residue and leave the area in the same condition as you found it.

On a regular basis, check the tanks for damage.

Preferably, you should plan this as part of your RV maintenance so that you can clean everything in one go.

Check to see that there is enough for your tanks, and bear in mind that there may be instances where you will need to connect a few of hoses in order to reach the sewer connection.

As a result of the decrease in cost, you don’t want to be trapped with an inoperative hose when emptying a black water tank in your home.

No matter what sort of hose you are using, never drag it over the ground since this might cause punctures or rips in the hose.

This should not be done with the black water hose, though.

It’s a topic that, for obvious reasons, no RVer can afford to ignore.
