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.

What is the capacity of an RV septic tank?

They are, on the other hand, frequently more accommodating than most people anticipate.

Tanks as large as 50 gallons apiece might be found in a larger recreational vehicle.

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.

You should strive to avoid emptying a tank that is less than two-thirds of the way full.
Many tanks are equipped with sensors that can assist in determining this.

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.
And keep in mind that the longer you can wait, the more time the waste will have to decompose inside the tank.
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.

What Is The Typical RV Holding Tank Size?

Whether you’re planning a road trip or living full-time in your RV, it’s critical to understand the capacity of your camper’s holding tanks. The amount of fresh water you can take for drinking, washing dishes, and showering, as well as the size of the RV’s tanks for gray water and sewage, must be determined before you leave home. Water hookups are available at almost every campground, and some sites even have dump stations where you can empty your gray and black water tanks. However, knowing the capacity of your tanks is still vital so that you can plan your trip correctly, especially if you’re traveling as a family or in a group.

Additionally, you may find yourself in a campsite without electrical or water hookups, and if your fresh water tank is low or empty, you may be need to purchase additional water for drinking and washing up.

It depends depend on the size of your RV how large your holding tanks will be, but on average, your fresh water tank will contain 20 to 100 gallons, your gray water tank will hold around 50 gallons, and your black water tank would store between 18 and 64 gallons.

What Types of Holding Tanks Do RVs Have?

Most recreational vehicles and campers are equipped with three types of tanks:

Tanks containing fresh water that feed water to your sinks, shower(s), and, in certain situations, your toilet

Water tanks that collect the waste water that drains from your sinks and shower(s) are called gray water tanks. Black water tanks, which are used to hold sewage from your toilet

It’s a good idea to empty your gray and black water tanks before they reach too near to the maximum capacity level. Most RVs are equipped with a sensor that alerts you when the tank is approaching capacity. If your camper does not have a sensor, you’ll need to keep a watch on the gray water tank to ensure that it does not fill up. Later in this piece, I’ll go through how to empty your holding tanks.

How Can I Tell The Capacity of My RV’s Tanks?

Opening your tank storage area and looking inside will normally reveal the volume of each individual tank, although this is not always the case. It’s possible that the tank capacity isn’t visible on the tank itself, but you can discover the sizes in your owner’s handbook instead. Alternatively, you may conduct an internet search using the make, model, and year of your RV to obtain the tank capacity data. It’s common for the manufacturer or seller’s website to provide the capacity of the tanks if you’re purchasing an RV and have questions about tank sizes.

Your fresh water tank’s capacity is always the first item on the screen to appear, followed by the capacity of your gray water tank, and finally the capacity of your black water tank.

What is the Typical Gallon Capacity of an RV’s Holding Tanks?

Generally speaking, bigger recreational vehicles (RVs) will have larger holding tanks, whilst smaller campers would have smaller holding tanks. However, this isn’t always the case, as some large RVs are built to seat fewer people than other models. Due to the fact that Class A RVs are the largest campers available, the holding tanks in these vehicles will be bigger, but Class B RVs and camper vans will have the smallest holding tanks available. Tank capacities also differ depending on the kind of tank used, with fresh water tanks having the most capacity and gray and black water tanks having the least.

Average Size of Fresh Water RV Tanks

Your fresh water holding tank may have a capacity of 20 to 100 gallons, depending on the size and class of your recreational vehicle. Fresh water tanks in Class A recreational vehicles are the largest in capacity, ranging between 72 and 100 gallons. Fifth wheel travel trailers, which are the next size down, often include fresh water tanks that store 50 to 92 gallons of fresh water on board. Class C RVs are available in a variety of sizes, with fresh water tanks ranging from 35 to 60 gallons in capacity.

Most travel trailers that are not big fifth wheelers have fresh water tanks with a capacity in the same range. Class B RVs and camper vans, which are the smallest recreational vehicles, typically contain 16 to 40 gallons of fresh water, if they have plumbing systems at all (some do not).

Average Size of Gray Water RV Tanks

The size of your RV’s gray water tank is frequently determined by the size of your RV’s living space and sleeping capacity. Your gray water tank will have a capacity of around 50 gallons on average across all RV classes and travel trailer types, with Class A and fifth wheel trailers having the most capacity and Class B having the lowest capacity. Gray water tanks in Class A recreational vehicles typically carry between 40 and 65 gallons of water. When it comes to fifth wheel trailers, the range is similar, although some trailers can carry as much as 93 gallons of gray water in the gray water tank.

Travel trailers are also available in a range of sizes, with the gray tanks in smaller trailers holding as little as 28 gallons and the gray tanks in bigger RVs holding as much as 78 gallons in some cases.

Average Size of Black Water RV Tanks

Despite the fact that the black tank in most RVs is smaller than the fresh and gray water tanks, it can fill up more quickly depending on how much you flush, how much toilet paper you use, and how often you use the toilet. Aside from the size and capacity of your RV or camper, you can expect the black tank to carry somewhere between 18 and 64 gallons on average. Fifth wheels typically feature the largest black tanks, which may contain anywhere from 39 to 88 gallons when fully stocked with waste.

In class C motorhomes, which are available in a variety of configurations, the black tanks range in size from 27 to 63 gallon capacity.

In the event that your Class B RV has a black tank (although not all have), it will most likely hold between 10 and 26 gallons of waste.

How Do I Empty My Gray and Black Water Tanks?

The fresh water tank in your camper can normally be filled from the water hookup at your campsite, but emptying the gray and black water tanks in your camper may be a difficult (and occasionally disgusting) part of owning a camper. Many RV parks and campsites will have a dump station that has been certified for this operation, but not all of them will have one. So, if you’ll be needing to empty your tanks at the conclusion of your stay, be sure to check with the campsite ahead of time to ensure they have one available for you.

How to Maintain Your Holding Tanks

Maintaining your gray and black water tanks in good condition is essential for reducing the ickiness of emptying them, as well as keeping smells down and avoiding nasty build-up or blockages in the pipes.

Some pointers for keeping your gray and black water holding tanks in the best possible condition are as follows:

If you want to optimize the area in your black tank and minimize blockages, you should only use specific RV toilet paper. Preparing your toilet before each trip involves filling it with water from an external source (such as a bucket), adding a dosage of black water tank treatment (such as Aqua-Kem), and flushing it once. By taking military showers and/or utilizing disposable plates and utensils, you may reduce your water use. Allowing your gray water tank to fill at least two-thirds of the way before emptying it can help to avoid buildup and make the cleaning procedure more efficient at removing scum from the tank. Never completely empty your gray water tank since scum will accumulate and generate smells and unclean conditions within the tank and hose
Instead, keep the tank half-full.

Steps for Emptying Gray and Black Water Tanks

Whenever possible, empty your black water tank before emptying your gray water tank. This is because gray water is cleaner and may be utilized to rinse up the black water hoses, whereas black water is less clean. Plus, who likes to reserve the most unpleasant and inconvenient work till last? It’s best to get it over with as soon as possible. @thebravewinnie When it comes to emptying your gray and black water tanks, follow these simple steps: There are a variety of signals that your RV’s sensors are indicating that your tanks are growing full and need to be emptied, including the following: 1.

In any case, it’s time to empty the tank and start over.
@airstream nuts and bolts2.

You should then unscrew the holding tank outlet cap and connect the waste hose between your camper and the dump station.
3.Drain your black water tank by opening the valve on the side of the tank.
When you’re finished, close the valve on the black tank and repeat the process with the gray water tank valve.

Lift the detached end of the hose to discharge any residual water from the hose into the dump hole at the bottom of the hole.
Remove the hose from the dump hole and water off the area surrounding the hole to remove any spillage that may have occurred.

How to Deal With Clogs in Your RV Holding Tanks

It’s crucial to understand that your gray and black water tanks are not the same as your home’s sewer system in this regard. They can become clogged or fail if you flush or drain the incorrect materials through them, or if they are not properly cared for. In order to prevent particles from entering your RV’s gray water tank, you should attempt to place strainers in the sink(s) and shower drains of your RV. For the sake of preventing blockages in your black water tank, you should always use specific RV toilet paper and never flush sanitary items or wet wipes (even if they are labeled as flushable).

An obstruction in your black water tank may also occur if you haven’t been dumping it frequently enough, haven’t been cleaning the tank or using the proper treatment chemicals, or even if you’ve been dumping too frequently, which results in a dry tank, as explained above.

If Your Black Water Tank Gets Clogged…

Always use gloves and protective eyewear to avoid coming into touch with human excrement, which is not only disgusting but may also be harmful to your health. Start by draining your black water tank completely, as this may help to clear the blockage completely. If this is not the case, the blockage might be in your waste pipe (which runs between the toilet and the black water tank)
Otherwise, Pyramid plugs can form in your waste pipe as a result of hardened waste build-up, and they can be difficult to remove. To unclog these blockages, you’ll need to use a toilet snake and a long, flexible auger to probe about within the toilet’s waste pipe until the line seems to be clean. Note: Only use toilet snakes or toilet wands that are specifically made for RV usage, since regular ones may pierce your tank or waste pipe.

If Your Gray Water Tank Gets Clogged…

To flush your pipes and break down any build-up, use a moderate cleaning procedure such as a little dish detergent and hot water. Allow the hot water to run for a while, then empty your gray water tank after you’re finished. Deep-cleaning your gray water system can also be accomplished by circulating a very dilute bleach solution through its pipes and within the tank itself. Consider putting ice to the tank and taking a brief drive to let the ice to’scrub’ the interior of the tank
This will help to prevent corrosion. Gray water treatment chemicals, as well as those for your black water tank, are both accessible, however they are not necessarily required to be used.

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. One issue was that we were unsure of how many gallons our RV could hold on its own. How many gallons of water does a typical recreational vehicle 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 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:

Simply spritz your hair with water. Turn off the water and work the shampoo into your hair thoroughly. Rinse well

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
Rinse your hair and body as rapidly as possible
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.

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
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.

Typical RV Holding Tank Size With 10 Examples

You have arrived to the following page: In this section, you’ll find information about typical RV holding tank sizes, as well as a list of 10 examples.

Even if you tried, it’s impossible to fathom traveling in an RV without sufficient holding tanks. Just as an RV without beds is ineffective, its bathroom and kitchen will be ineffective if the holding tanks are not present. A typical recreational vehicle is comprised of two types of storage tanks:

One type of holding tank holds freshwater

Other types of holding tanks contain wastewater.

Those who are familiar with the use of these tanks may be interested in understanding the answer to the question, “What is the normal RV holding tank size?” For individuals who are just getting started with their interest in these recreational vehicles, don’t jump on to the following part. So, what is the typical size of a recreational vehicle’s holding tank? A holding tank will typically contain between 25 and 100 gallons of liquid. It is estimated that a class A RV will hold around 80 Gallons, a class C will hold approximately 30 Gallons, and a class C will hold approximately 70 Gallons.

Types of RV Holding Tanks

Before I go into the specifics of RV holding tank sizes, it’s important to remember that there are three different types of holding systems. Let us have a look at these systems and their intended uses:

Gray Water Tank

When you take a shower, wash your face, or wash your hands, the remaining water travels through the pipes and is collected in a gray water tank to be used later. It’s common for this water to contain soap residue or food particles.

Black Water Tank

The toiletwater that has been flushed out is collected and kept in a wastewater tank known as a black water tank.

Freshwater Tank

The term “water storage tank” refers to a container that stores fresh water and allows it to flow through your RV’s plumbing system when you do not have access to your city’s water supply. It is important to note that all three tanks are completely distinct from one another and require regular maintenance to work properly.

What Size are RV Holding Tanks?

The volume of your RV’s tank may have a big influence on your travels. Consider the following scenario. You’re on a relaxing vacation with your friends and family. Everyone is gathered around a campfire, snacking on marshmallows. Your RV is only a few feet away from where you are standing. An individual makes a fast trip to the restroom, only to return in a state of shock when they discover that the RV’s waste tank has hit capacity and freshwater is running low. Isn’t it a little disturbing? The only option in such a case is to pack up and find the nearest public sewer where the wastewater can be disposed of properly.

As a result, you must select a holding tank size that is appropriate for your requirements.
Greywater tanks with a capacity of 32 gallons or more are more common than black water tanks with a capacity of 15 gallons or less.

The length of time it takes for your tank to fill to capacity, on the other hand, is dependent on how much you use it.
When traveling with multiple people, however, the same water will not last nearly as long.

How Do You Know When Your Holding Tank has Reached Full Capacity?

Most recreational vehicles are equipped with a built-in mechanism that allows you to monitor the capacity of each tank individually.

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.

(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.

An essential point to remember is that you should avoid emptying your tanks before they are completely filled, especially in cold weather.

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.
