# What Size Septic Tank In 87 Sunstream Motor Home? (Question)

• The volume in cubic feet of a tank of these tank dimensions is 4.5 x 8 x 6 = 216 cubic feet. Since one cubic foot can contain 7.481 gallons, which we round up to 7.5 gallons per cubic foot: 216 x 7.5 = 1620 gallons of septic tank capacity – this is probably nominally a “1500-gallon septic tank”.

## What size septic tank do I need for a 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.

## How big is a black tank on an RV?

Black tanks vary in size anywhere from 15 gallons to 50 gallons. The size of your black tank will determine how long you can use your RV toilet without emptying the tank into a sewer at a campsite or designated dump station.

## How much sewage does an RV hold?

A typical RV holding tank size will range from 10 gallons to 100+ gallons. Generally, the bigger the RV, the bigger the septic system for RV will be. Travel trailer holding tanks will generally be smaller than motorhome holding tanks because trailers are usually smaller than motorhomes.

## How many gallons does a black tank hold?

Capacities for black water tanks range in 5 gallon to 202 gallons, with tank thickness ranges from 0.25 inches (1/4″) to 0.375 inches (3/8″). When installing or performing maintenance, all care, handling, and procedures should be done specifically for wastewater holding tanks.

## How big should my septic tank be?

The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank. On the other hand, a bigger home of approximately 2,500 square feet will need a bigger tank, more than the 1,000-gallon range.

## How do I determine the size of my septic tank?

The formula is length (feet) x width (feet) x 1 foot x 7.5 gallons, which is the volume for 1-foot depth. To find the volume for 1 inch I divide the volume by 12 to give me gallons per inch. For our example this is 5.16 feet x 7.5 feet x 1.0 foot x 7.5 gallons per cubic foot = 290.2 gallons.

## How long can black water stay in RV tank?

How long can you leave waste in a black tank? Our research shows that most camping experts maintain that you can safely leave black water in the tank for up to ten days. Most, however, state that you should empty it out after no more than a week.

## What is GREY tank on RV?

The Grey Tank The RV gray tank holds waste water from every source other than that is not the toilet, which includes your kitchen sink and bathroom/lavy sink. Soapy water, toothpaste, dust and dirt from your afternoon hike, or anything else you rinse down the sink drain ends up in the gray tank.

## How often should I dump my black tank?

Dumping your black water holding tank every 3-5 days will help control odors. Having enough water in your holding tank is absolutely critical to suppressing odors! Without enough water, the aerobic bacteria in your tank won’t be properly hydrated, resulting in less-effective waste breakdown and odor elimination.

## How big of a water tank Do I need RV?

So, what is the average RV holding tank size? Expect a holding tank to be between 25 and 100 Gallons. A class A RV will average 80 Gallons, Class C will average 30 Gallons, and as class C will average 70 Gallons. Travel trailers will be around 40 Gallons.

## How do I connect my RV to my septic permanently?

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.

## How long does a 30 gallon black water tank last?

A 30-gallon black water tank can last up to six days. The size of the wastewater tanks (grey and black water) depends on the manufacturer of the caravan and the design of the caravan.

## How do you know when black tank is full?

There is another way to know your tank is full (or close to it) besides using sensors or sound. “Sound” is also a good indicator, but in addition to that method, the closer to full, the more it smells (even if you use chemicals). You’ll want to dump for sure when you can’t take the smell any longer.

## What size holding tank do I need?

For large properties with significant landscaping and a large home we recommend a minimum of 10,000 gallons. For smaller properties and homes that don’t have to worry about fire considerations, 2500-3000 gallons is a common tank tank that will give you plenty of water for daily needs.

If not hooked to a field how often are you willing to pay to have it pumped? Are you going to empty the gray into the tank also? Are you thinking of a seperate field for the gray water? If your going to dump black only and pump it then a 350 gal. tank will last over a month. Gray on the ground will work if you have space and no neighbors too ding you.

 08-04-2020, 06:13 PM 5 Senior MemberMonaco Owners ClubJoin Date: Jun 2014Posts: 10,466 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
 08-04-2020, 08:46 PM 6 Senior MemberJoin Date: Apr 2015Location: Rogers, ARPosts: 1,641 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. Twice a year is better than once a month though._2004 Beaver Monterey Laguna IV Cummins ISC 350HP Allison 3000 6 speed2020 Chevy Equinox Premier 2.0t 9 speed AWD
 08-05-2020, 06:55 AM 8 Senior MemberJoin Date: Jan 2017Location: Nashville, TN areaPosts: 4,577 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.

Most “experts” say that there is no need to use a RidX type product if you use your system correctly. 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.

 08-05-2020, 11:51 AM 11 Registered UserMonaco Owners ClubJoin Date: Mar 2018Location: Blairsville, GAWPB, FLPosts: 3,993 I would tap into the existing house septic system, even if I had to use a macerator to pump to it, if it’s higher up from the RV pad. 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: 24,778 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 Many Gallons of Water Does an RV Usually Hold?

Although we always had a camper, it was always on a designated lot with its own water tank when I was a kid. Then my family and I made the decision to relocate it to a new location, and we ran into some difficulties. A major concern was that we were unsure of how many gallons our RV could hold on its own. How many gallons of water can a typical RV hold? A typical freshwater tank may store between 20 and 100 gallons of freshwater. A class A recreational vehicle will contain the most water, with an average capacity of 75-100 gallons.

Smaller trailers have a freshwater capacity of 40-60 gallons.

## What Are the Other Two Tank Numbers?

The grey and black tanks are the other two tanks in your system. When purchasing an RV, you will see information such as “water tank size is 65-25-30.” The freshwater tank will contain 65 gallons, the grey water tank can store up to 25 gallons, and the black water tank should hold less than thirty gallons, according to this calculation. The size of your waste gallon containers is determined not just by the size of your freshwater tank, but also by the kind of RV you have. Some RVs are designed to accommodate a single person, while others that are designed for families have larger tanks to accommodate everyone’s needs.

#### What is My “Gray Tank?”

The water that has been used by the cleaning appliances in your RV, such as your sinks, shower, and (if you have one) washing machine, is collected in your grey water tank and disposed of appropriately. They are fed by the freshwater supply and the water that is used is channeled into the greywater tank once it has been used. Please keep in mind that your grey tank may fill up far more quickly than your freshwater tank can be drained!

#### What is the “Black T ank?”

This is the aspect of RVing that everyone enjoys the most. The black tank is often referred to as the septic tank in your recreational vehicle! There is nothing else that can fill this tank but the waste that comes out of your toilet. Keep an eye on how much fuel is left in this tank and take good care of it. Also, keep in mind that black tanks can be temperamental. It is recommended that you use RV toilet paper to guarantee that the least amount of product gets caught in your RV system. Additionally, while using your RV’s toilet for the first time on each trip, fill it with water from outside the vehicle and flush it once.

## How Do I Dispose of the Water in The Black and Gray T anks?

You must first locate a septic dumping spot that has been approved before you can get down to business when your weekend is done. (They are usually accessible at most RV parks.) Ensure that the waste pipe is connected to your black or grey tanks. Please remember to empty your black tank first, and then, once it has been completely emptied, you may start running your grey water. We do this because your grey tank is filled with much cleaner water than your black tank, and it has the ability to remove unwanted items from your garden hose.

You may find yourself straying off the usual route from time to time.

You may use this as a temporary holding tank before transporting your garbage to a proper waste disposal facility. Following the disposal of this portable tank, make certain that it is properly cleaned by running clean water through it.

#### Black Tank Flushing

After a period of time, your tank will become clogged with extra toilet paper and other items that will be difficult to remove with frequent emptying. In order to prevent this, a black tank cleansing will be required on occasion. When attempting to winterize your RV, this is extremely important to remember! Most recreational vehicles are equipped with tank cleansing valves, which may be used at any regular dumping station. You will connect everything as you normally would, but now you will flush your toilet with regular water while also turning on the black tank flushing valve.

#### How Long Can I Go Between Filling Up and Dumping My Tanks?

Your is dependent on the number of people that will be traveling with you in your RV on this journey. I would say that if it’s just you and one or two other individuals, you’ll be OK for a week. Be mindful of your tank gauge, which will indicate how full your tanks are, just like a fuel gauge would indicate how much petrol you have left. A good rule of thumb is to empty them when they are about two-thirds full. (Be careful that your grey or black water tanks may fill up more quickly than your freshwater tanks decrease).

## How Do I Conserve Water in an RV?

You should learn how to save water if you have a large group of people in an RV and just a limited amount of resources to empty and refill tanks. The shower is one of the most significant water wasters. A suggestion would be to take a shower in the military style:

1. Simply spritz your hair with water. Turn off the water and work the shampoo into your hair thoroughly. Rinse well
2. Put a stop to the water and, if you’re using it, a conditioner in it. Make use of a damp loofa or washcloth to clean your body
3. Rinse your hair and body as rapidly as possible
4. You are finished when you turn off the water.

This will save a tremendous amount of water. All of the time spent shampooing and scrubbing your body is simply a waste of water. Water and time are saved by dressing in a military fashion. No one likes to stand about in the rain, cold, and nude for lengthy periods of time. Other pointers:

• Use disposable paper and plastic plates that can be thrown away to conserve water by avoiding the need to wash dishes on the road. Instead than needing to wash your hands many times throughout the day, use hand sanitizer instead. Make sure you have plastic water bottles with you for drinking and other activities like brushing your teeth.

## Winterizing Your RV Water Tanks

If you do not properly care for your tanks after the RVing season is done, you may see algae and mildew growing in your tanks. As a result, when winterizing your tank, be sure to employ your filtration system to keep everything empty during the periods when you will not be using it at all.

1. First and first, empty your water heater. Make a note of the lowest point in your water system to ensure that all of the water is drained
2. Make sure that your freshwater tank is entirely depleted by using your water pump. Then, using a white non-toxic hose, fill it with bleach and water to finish it out. For every 15 gallons of water, 1 cup of bleach is used. Drain the tank once again, fill it with regular water, then empty it to ensure that there is no bleach in the water you will later use to clean yourself.

5th Wheel Trailer 1 to 8 18 to 40 feet \$15,000 to \$50,000

In order to properly maintain my black tank, I’ll need the following items. The black tank must first be topped out with liquid before it can be used to keep it functioning properly and to alleviate the stench. So first fill it with clean (or at least clean-ish) water, and then add a holding chemical to keep it from drying out. This aids in the decomposition of waste in your black tank. There should be instructions on the container indicating how much to use for the size of tank you have purchased.

On your RV, there should be a gauge that indicates how much fuel is left in the tank.

It’s normal for the toilet to almost “burp,” or release gas from the sewer, when the tank is nearly full; this is simply expelling any remaining gas and making the greatest space possible for waste.

## RV Holding Tanks: The Ultimate Guide on Holding Tanks for RVs

Your RV holding tanks are responsible for allowing you to use the restroom — as well as the shower and the kitchen sink — while traveling without leaving a trail of wastewater behind. Holding tanks, as the name indicates, are used to store wastewater generated by your home and store it beneath your coach until you are ready to dump it into a public sewer system. There is also a freshwater holding tank, which allows you to use fresh water even if you are unable to connect to the city’s water distribution system.

Everything you need to know about RV holding tanks will be covered in this essay, from how to distinguish between black and gray water (which is critical!) to how to unclog a stoppage.

As previously stated, there is not (often) a single holding tank for your RV; rather, there are three different holding tanks for your RV to use.

Each requires certain maintenance practices to function properly; for example, you must put particular chemicals in your black water tank to aid in the breakdown of solid waste and the preservation of the odor-free operation of your RV toilet.

But first, let’s go back to the beginning. What precisely is the black water holding tank in an RV and how does it function? And what other options do you have for RV holding tanks? The three distinct RV holding tank systems are shown in the diagram below.

• Water that runs from your sinks and showers is referred to as gray water. In other words, it is the reasonably clean wastewater that may contain soap residue or food particles, but which normally does not contain anything particularly noxious. Water that has been contaminated by human feces is referred to as black water. A fresh water tank may also be installed, letting you to utilize your onboard plumbing system even while off-grid camping or boondocking.

In order to keep them functional (and as odor-free as possible! ), each camping holding tank must be dumped (or filled) individually and maintained in accordance with the manufacturer’s recommendations. In particular, many campers are interested in the size of their RV’s holding tanks, because it is the tank capacity that has the ability to compel you to finish a boondocking camping vacation sooner than you would have liked. After all, once your wastewater tanks are full (or your freshwater tank is dry), you will have no alternative but to connect to a city sewer and water hookup in order to dispose of the old and replenish your supplies with the new.

courtesy of GIPHY However, the good news is that the normal holding tank size for an RV is actually quite acceptable.

(Obviously, larger recreational vehicles will have greater holding tanks, in basic terms.) No matter what large your tanks are — and the only way to know for sure is to contact your dealer or owner’s handbook — the length of time you may go between dumping operations is a question of personal preference.

• Having discussed tank size and capacity, let’s move on to what occurs when those tanks reach capacity: dumping.
• Most recreational vehicles are equipped with an onboard sensor system that allows you to monitor the levels of each separate tank.
• umm.
• watching things rise to the surface.
• An essential point to remember is that you should avoid emptying your tanks before they are completely filled, especially in cold weather.
• If you want to dump your tanks, you’ll need to step outside your RV and find a location along your sideboard where the waste tank valves are located.
• This is standard practice.

In order to prevent it from coming free and causing a really nasty mess, you may want to have someone lay their foot, or even a block, on the end of the pipe that connects to the municipal sewage.

Always empty your black tank first; this will allow the gray tank to wash out your hose with its comparatively clean water once it has been drained.

Whether or not your campground is linked to a sewage system, close both valves when the tanks are completely empty—leaving them open is a surefire way to create a clog, as the liquid waste water will flow through while the solid waste is allowed to build.

Potable water hoses are often white in color, making them simple to distinguish from other types of hoses.

Draining your tank is accomplished by opening the drain valve located at the bottom; refer to your owner’s handbook for precise instructions on how to do so.

What happens if you have a clog in your drain?

You should constantly use a good black tank deodorizing and cleaning chemical, which will aid in the breakdown of solid waste and the preservation of the fresh scent of your toilet.

The compounds are available in both liquid and powder forms, but employing them makes a significant effect regardless of the form.

If your fresh water tank is polluted or smells bad, you may clean the RV’s holding tank using regular home bleach to eliminate the odor.

• Run the water until you can smell the bleach, then turn off the water and let the tank to rest for at least 24 hours after you have drained all of the bleach water. Fill the tank with water and then run the water again until the bleach smell has disappeared. After that, you may refill the holding tank as usual.

If you use RV holding tank cleaning and empty your tanks on a regular basis, the odds of encountering a blockage are little to none. Also keep in mind that you should only use toilet paper designed exclusively for RVs, which will help you avoid a clog in the first place by preventing it from occurring. Quick-dissolve toilet paper is significantly gentler on the sensitive systems in your RV. It is also lot less expensive. Having said that, if you find yourself in the position of having to unclog your holding tanks, you don’t want to employ the same type of rough-and-tumble approach you would use on your household metal pipes.

1. A typical procedure is replacing the RV toilet and plumbing system with a conventional, residential commode and completely removing the RV holding tanks.
2. Because this type of plumbing is not usually straightforward or simple, you may need to hire assistance.
3. RV holding tanks and plumbing systems are not as reliable and durable as the ones you are accustomed to at home!
4. How to clean the holding tank sensor in your RV by pouring soapy water through the whole system is demonstrated in this video.

#### Newark, Delaware, United States

Gulf Stream 34 in 1987 “RV 454 Chevy P30 chassis with three-speed automatic transmission, twin rear wheels, and a receiver hitch in the back. The engine is robust, and the tires appear to be in fair condition. I have a folder that has documents and invoices, as well as the owners manual. Several of my receivers have had their brakes re-done by the previous owner in 2015. Some windows were also resealed as part of the restoration. The RV is a competent driver, although it might use some improvement.

• The side markings appear to be quite recent.
• It does run well, but I’m not sure how many miles it has covered.
• I had to “hot-wire” the back air conditioning unit in order for it to work properly.
• Due to the fact that most campgrounds have two outlets, my intention was to add a second 120v shore power plug to run both air conditioners at the same time.) The propane tank and stove are operational; however, I am unsure how to switch on the heat.
• In its place appears to have been installed an apartment unit that operates on 120v alone.
• The generator starts straight up, but it will need to be serviced shortly after that.
• It need a new sink faucet since it leaks from the top and we are unsure if it has any more leaks.

The RV features a split windshield, with a fracture in the right windscreen.

The cab’s air conditioning should be examined, and the heating control valve should be changed if it is sticking.

I have not seen any water leaks in the roof, with the exception of a dribble under the driver’s seat during a heavy rainstorm.

The RV needs some paneling replaced in the front on the passenger side, which appears to have been damaged by water in the past.

The floor in front of the stove is a touch spongy, so I changed a few tiles there to make it more firm.

The 12-volt system looks to be in good working order.

The cab audio and microwave both function properly.

The front cabinets are sagging a little bit on the edge of the front edge.

For additional information, send an email or give us a call.

I need to get it moved as soon as possible.

I’ve publicized it locally and retain the right to stop the auction early if the situation warrants it.

If you are not a Delaware resident, I can give you with a temporary tag. Send me an email if you want additional pictures and information. Keep track of how many times a page is visited. With the help ofAuctiva “s COMPLIMENTARY Counter

## 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.
