What If The Septic Tank Is Higher Than The Rv? (TOP 5 Tips)

What is the difference between an RV holding tank and septic system?

  • Even though RV holding tanks and home septic systems both handle “household” waste, there is one important distinction between them. An RV is designed only to transport the waste, while a septic system is designed to treat the waste and return clean water back to the water table.

How high should my septic tank be?

A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).

Can you park above a septic tank?

Parking or driving over a septic tank is never a good idea, but it’s even riskier in wet conditions. When the ground soaks up abundant moisture, a large amount of weight (like that of a vehicle) atop the movable soil can cause a shift in the ground.

Can an RV be connected to a septic tank?

Many people who have an RV and a septic tank wonder if they can use the two together. The RV is the perfect place to allow visitors to stay while having their own space. The short answer is that yes, it is possible to connect your RV into your septic tank, but you need to make sure that you do it correctly.

Should a septic tank be full to the top?

Do not stand on the top of the tank as it could collapse due to concrete corrosion. The Septic Tank will be one of two types: A modern ‘onion’ shaped septic tank, in which case there will be only one lid with a ‘tube’ of around 600mm.

How can I tell if septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  1. Your Drains Are Taking Forever.
  2. Standing Water Over Your Septic Tank.
  3. Bad Smells Coming From Your Yard.
  4. You Hear Gurgling Water.
  5. You Have A Sewage Backup.
  6. How often should you empty your septic tank?

Can heavy rain affect septic tank?

It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.

Can you pour concrete over septic tank?

It is never recommended to build a structure over any portion of your septic system. No permanent structures should be built over any portion of the system, but at least in this case the homeowner can pump out their septic tank.

Can you build a deck over a septic tank?

You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.

Can I put pavers over septic tank?

You can’t build a paver patio on top of a septic tank, and doing so could be against the planning laws of your state or local area. Septic tanks can take very little weight without getting damaged, and you’ll also need access to the tank in the future too. You shouldn’t build a deck on one either.

Can I dump my RV black water into my septic tank?

In summary, yes you can dump RV waste water into house septic systems. Don’t use chemicals in your black water tank that may destroy your tank’s natural ecosystem. When dumping from an access port, try to make sure you’re on the correct side of the baffle.

How big of a septic tank do I need for an RV?

In a small RV, you can expect at least 15 gallons for the black water and a gray water tank of 30 gallons. A larger RV might easily have tanks as large as 50 gallons each.

Are RV toilet chemicals safe for septic tanks?

Camco TST Clean Scent RV Toilet Treatment, Formaldehyde Free, Breaks Down Waste And Tissue, Septic Tank Safe, Treats up to 8 – 40 Gallon Holding Tanks (32 Ounce Bottle) – 41502, TST Blue.

Why is my septic tank always full?

An overfilled septic tank is often a signal that your drain field is malfunctioning. The drain field is the final fixture in the septic system and serves the purpose of returning treated effluent back into the soil.

Can I shower if my septic tank is full?

Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.

Why is my septic tank filling up so fast?

If your tank seems to be filling up much more quickly, it could indicate a problem with one of its components, or it could be a sign that your tank is taking on more liquids than it can handle. Call a local professional if your tank is needing more septic pumping than usual.

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.

The garbage and water are transported through pipes after each flush or each time the faucet is operated. A septic tank is used to dispose of waste that has been generated in the residence. It is designed with an entrance mid-way down to prevent blockages from forming. A baffle in the center of the tank keeps sludge, grease, and oil from exiting to avoid obstructions from forming. Wastewater is able to travel through this hole. 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;

What if I use chemicals in RV waste water tanks?

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

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

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

How to dump RV waste into house septic systems

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

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

Use caution when using a house septic system access port

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

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

What about dumping RV gray water into house septic systems?

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

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

Conclusion

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!

Is It Legal to Connect Your RV to a Septic Tank?

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.

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.

Another consideration is the amount of rooms in the residence. The premise is that a house with a predetermined number of rooms will generate a predetermined amount of garbage. 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. You may discover their locations all throughout the country by visiting their website or downloading their mobile device applications.

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

Senior MemberMonaco Owners ClubJoin Date: Jun 2014Posts: 10,511 I would contact the county health/environmental department and talk to them. There may be a minimum size that would work for what you want. My guess a 300 gallon would be enough along with ~100 ft of drainfield but that depends on you perk testing. You will need a drain field unless you plan on pumping, which would be a pain. Depending on the county requirements this could be stone filled trench or composite type.Also, if you decide to add a septic system I caution against using any type of RV Black tank treatment. I might play havoc with the septic tank.I built a new house and had the septic installed in 2017. My wife does dog grooming and I wanted a large enough system to handle that plus the 4 bedrooms, so I opted for a 5 bedroom system which required a 1250 gallon tank and 550 of drain field (110 ft per bedroom). Permit cost $250In my case the health department required a soil study meaning I had to hire a guy to dig a couple holes, look the soil type, and write a report (that I had to correct). The study cost $300.Install was pretty straight forward, cost $6500.I ran the lines to have an RV dump in the parking area that I excavated, I actually added a second one if we have visitors._Jim J 2002 Monaco Windsor 38 PKD Cummins ISC 350 8.3L2005 Jeep Grand Cherokee w/5.7 Hemi

Senior MemberJoin Date: Apr 2015Location: Rogers, ARPosts: 1,648 My opinion would be that you would need a larger tank, which will require a larger leach field.You are saying a 60 gal dump every two weeks, thinking only a small tank will take care of this.The problem is that a septic system is a “trickle” system. Only a small amount of water normally trickles into the tank on a continuing basis, and trickles out into the leach field the same way. An operating septic tank is normally full of water and as 1/2 gal. trickles in, 1/2 gal trickles out to the leach field where it gradually soaks into the ground. A smaller tank won’t have the capacity to take a 60 gal dump without filling the intake pipe and possibly flowing out your dump cap. If you install a 60 gal capacity intake pipe, to dump into, then it can trickle into, and out of the tank, then you should be good. Septics just aren’t for high flow water volume.Another thing about septics is that they operate on bacteria to digest the solid waste. If you flush disinfects down, that can kill the bacteria and stop the digestive action in the tank. A tank usually requires continuous adding of the bacteria agent._2019 Fleetwood Discovery LXE 40M w/2021 Equinox

The perk tester I called recommended not getting a permit since it is a second septic on property and only for the RV. I don’t have an issue with that as there are no neighbors but I want it to work. I may request a bigger tank just because. I don’t mind getting it pumped.

Senior MemberJoin Date: Jan 2017Location: Nashville, TN areaPosts: 4,591 Tank size determines how long the stuff stays in the tank and gets broken down by bacteria. Field size determines how much effulent can be soaked into the ground.If you use a tank that’s too small you stand a chance of introducing raw sewage into the field lines. If you don’t have enough field lines you can water log the field lines.In most locations septic systems are pretty well regulated and designs are critical. Failing to properly size the system can pollute the local area and ground water with some pretty nasty bacteria. I would suggest you consult the local health department or whoever regulates septic systems in your area.If your main concern is that it works properly that would be the best way to go. Septic permits are usually in the $100 range and you get a lot of design assistance for that price. If you’re trying to sneak something past the regulations then ignore this post.Nobody on here can determine field or tank sizing unless they have some knowledge about your soil makeup._When seconds count, the police are only minutes away.2019 Newmar Canyon Star 3627 on a 2018 F-53 26K chassis w/6 speed transmission2017 Jeep Wrangler JKU with Ready Brute tow system w/Currie Tow PlateTitusville, FL when not on the road

Some of the recommendations I found wereDo not use a garbage disposal disposal to send food waste to the the septic system. It will not break down easily.Limit harsh chemicals, I actually put a bypass in for the two laundry rooms I built knowing my wife uses bleach to disinfect dog stuff.Limit water use, that is why I installed the largest tank I could find, to help offset my wife’s high usage.No RidX or equivalent.If you do things right you won’t have to worry about pumping for +10 years, or longer depending on specific circumstances.

The grey water could go into a French drain (5-10’ of gravel in a 2’ wide trench) and once a week pump the black to the house septic.In GA (clay soils) you can legally put 10 RVs (no washing machines) on a normal house septic system (1000 gallon tank). If you want separate system for the RV I would use a 275 gallons plastic tote and 3 sections of plastic drain field chambers.

USAPosts: 24,795 alank is correct in his warning about overwhelming a too-small tank, though we could debate forever whether “too small” is 300 or 500 or 1000. His warning is the reason I suggested 1000 even though 500 is probably large enough. Just trying to be cautious.For the reason alank cites, it’s better to dump 20-30 gallons more often than 60 gallons every once in awhile.Note that the black tank contents are already partially digested when dumped, so you shouldn’t be putting a bunch of thick solids and paper into the tank all at once. It is, however, enough viscous fluid to add several inches of water to the tank until it drains off. Modern tanks usually have baffles to prevent the nastier stuff from proceeding directly to the drain field exit pipe, though._Gary BrinckFormer owner of 2004 American Tradition and several other RVsHome is in the Ocala Nat’l Forest near Ocala, FL

How Big Is An RV Septic Tank?

One thing that scares off more people than anything else whether they are new to the RV lifestyle or are just thinking about it is the prospect of living in one. To put it another way, the septic tank is being dumped. When people think of having a small kitchen or taking brief showers, they don’t consider it to be a major inconvenience. However, it is when they begin to consider the inconvenience of emptying the “toilet” tank that they begin to have serious doubts about the whole proposition.

  1. What is the capacity of an RV septic tank?
  2. They are, on the other hand, frequently more accommodating than most people anticipate.
  3. Tanks as large as 50 gallons apiece might be found in a larger recreational vehicle.
  4. Explain the difference between black water and gray water, as well as the third tank in your RV – the fresh water tank – in this section.

What Are The Different Tanks?

It’s critical to understand the various tanks in your recreational vehicle to get started. The size varies based on the size of your recreational vehicle. However, all recreational vehicles have more than one tank. There is a distinction between the fresh water tank, the gray water tank, and the blackwater tank. The term “fresh water” refers to precisely what it sounds like. It is the tank that contains the water that you can drink. When you turn on the faucet or turn on the shower, here is where the water is sourced.

  • Gray water is the water that collects after it has been emptied from a sink or shower and is considered to be unclean.
  • However, the polluted toilet water does not belong here; it has its own section.
  • As previously stated, it is kept separate from the gray water since it requires a higher level of caution when disposed of.
  • Occasionally, the gray water and black water tanks in an RV will be combined into a single tank.
  • This isn’t very common, and it’s usually seen in relatively small recreational vehicles.

How Many GallonsDoes An RV Black Water Tank Hold?

The size of each tank is determined by the overall length and width of the RV. An RV designed to accommodate eight people will require larger tanks than an RV designed to accommodate two people. The fresh water tank is, on average, the biggest of the three tanks. According to RVing Know-How, it has a capacity of somewhere between 20 and 100 gallons of liquid. The gray water tank holds around 50 gallons on average. Black water tanks have a capacity of 18-64 gallons. While a larger tank may appear to be the best option in some situations, it is not always the case.

A huge tank will either be completely empty while it is scarcely utilized or will take an excessive amount of time to fill.

A tiny tank is simply inconvenient – who wants to have to find time to empty their tank on a daily basis?

This will allow you to receive an estimate of how many gallons you fill each and every day.

This way, if you’re staying somewhere without access to a dump station or sewer hookups, you’ll be able to estimate how many days your tank will last. It might also be useful if you intend to travel for a longer period of time than usual and need to factor in time for dumping.

How Often Do You Need To Dump RV Waste?

Pouring the waste water from the black water tank requires some level of accuracy. The longer you wait, the more likely it is that it will begin to smell. Contrary to popular belief, according to Colton RV, the most prevalent problem is emptying too rapidly. It takes time for the waste in the black water tank to be broken down. Furthermore, the more filled the tank is, the easier it is to flush out. Solid waste tends to remain in the tank if there isn’t much in it to begin with when you dump it.

  1. You should strive to avoid emptying a tank that is less than two-thirds of the way full.
  2. Many tanks are equipped with sensors that can assist in determining this.
  3. The fact that RV toilet paper decomposes more quickly than ordinary toilet paper is one of the reasons why you should go for it instead of regular toilet paper.
  4. And keep in mind that the longer you can wait, the more time the waste will have to decompose inside the tank.
  5. This makes flushing it out a lot less difficult.

Can You Dump Black Water On The Ground?

The black water tank should never be dumped on the ground. It’s teeming with germs and potentially dangerous. When it enters the environment, it has the potential to spread illness and inflict significant damage. Always dispose of black water waste in a proper manner at a disposal site for recreational vehicles. Unlike the black water tank, the gray water tank is not nearly as poisonous. It can’t just be dumped “wherever” because there are still safety factors to take into consideration. For example, soap has the potential to be harmful to the environment.

However, with effective filtration, some RV owners are able to find other uses for the water, therefore decreasing water waste.

Where Is The Black Water Tank In My RV?

Following the gray water tank, the black water tank is positioned below and adjacent to the RV carriage. Of course, if you have two different tanks – some compact RVs just have one – this isn’t a problem. The process of locating and emptying the black water tank might be difficult for first-time users. Utilizing a dump station and emptying the black water tank on your own may be made more comfortable with the aid of this instructional video. Always begin with the black water tank and work your way down to the gray water tank.

How Long Will A Black Water Tank Last?

It’s difficult to determine how long a black water tank will endure in the long run. Over time, the plastic used to construct the tank deteriorates and becomes brittle. It doesn’t matter how carefully you take care of the tank at this time; it is just nearing the end of its useful life at this point. While it is rare, it is possible for a tank to endure for more than twenty-five years before this occurs. Tanks, on the other hand, do not always make it to this stage. Damage happens most frequently as a result of inappropriate handling or storage.

This may be accomplished with a regular garden hose.

This might cause serious damage.

When the RV is not in use for more than a week, it is recommended that the tanks be emptied.

If there is any possibility that the water in the tank will freeze while it is being stored, however, do not follow this recommendation. Instead, drain all water from all tanks and pipes to avoid the risk of their cracking and breaking. Prepare your RV for the winter, as seen here:

What Are Black Water Tanks Made Of?

The black water tank in most recreational vehicles is composed of an unique type of plastic. ABS plastic, commonly known as polycarbonate plastic, is also utilized in the plumbing industry. Some tanks are built of low-density polyethylene, which is lightweight and durable (LDPE). This is easily distinguished by its milky, nearly transparent look. Tanks constructed with LDPE are extremely difficult to repair. They are resistant to the majority of solvents, and the majority of crack repair procedures are ineffective.

  • ABS plastic, on the other hand, can be repaired in some instances.
  • It’s possible that it’s not worth it.
  • After only a few weeks, the material begins to disintegrate – you can repair one hole, but after a few weeks, there’s another.
  • It’s just easier to replace than it is to cope with leaks from your toilet tank, smells, and other unpleasantness for an extended period of time.

In Closing

The majority of recreational vehicles have three tanks. The potable water is stored in the fresh water tank until it is needed. The gray water tank gathers the water that has been used in the shower and in the sink. The black water tank is where the used toilet water is stored and disposed of. Depending on the RV, there may or may not be a gray water tank, and all used water is collected in the black water tank. For optimal results, empty the black water tank when it is nearly full – never less than two-thirds of the way full.

Always dump your RV’s black water at a dump station, both for legal and hygienic considerations.

Using a hose, flush the tank on a regular basis to prevent waste left behind by mistake from collecting in it.

Can I Dump My RV Holding Tank In My Residential Septic System?

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.

You should also look into the legality of the situation, and you should determine whether this is the best decision for you. 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

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

  • TheFlojetis a nice alternative, as is this pump fromShurflois, which is somewhat less expensive.
  • The use of clear elbow pipe connections may be beneficial in recognizing when your tanks are empty and when they are clean, as previously discussed.
  • Here’s a low-cost alternative.
  • Take into consideration choosing a long, thick hose, which will be more durable and will provide you with greater versatility.
  • In addition, sewer hose supports are a smart idea for keeping your hose in position and going downhill.

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.

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!
