The 4 Essentials for Maintaining RV's Plumbing

Running water and a good plumbing system is essential for a hassle-free RV life. It is quite possible that you think you are finished with your RV because it comes with the plumbing system installed. The key is to understand how each piece works within the plumbing system. A plumbing system is time-consuming and requires care when you are building an RV from scratch. 

What's the Process of Making Water In An RV?

Initially, RV plumbing systems depend on the type, size, and model of the motorhome. A basement is an ideal place for RVers to store tanks and more substantial equipment. Fresh water and wastewater can be brought in and taken out from the RV's water tanks when required. The portable tanks can be filled with water from the city's water system by attaching a food-grade hose. In order to have drinkable home water, you'll need to connect your RV port with 'city water.' You'll place the rig on the RV's exterior and connect the city water with your RV hose and drain hose. The hose should only be used for drinking water. Make sure to only connect the campground, the house, or any other reliable source of drinking water to city water.

RV Water Tanks & Systems

The RV plumbing system includes sinks, showers, and toilets in addition to the more conventional basement plumbing equipment.

Freshwater tanks are a vital part of RV plumbing. For clean and safe drinking water, you must use a freshwater tank. Water tanks of various sizes can be used for dry camping and boondocking. Different types of freshwater tanks are available depending on the size of your vehicle. 

This gray water tank stores all wastewater from your RV, especially that which drains from sinks and basins. Along with the RV kitchen sink and small RV bathroom sink, the gray water tank is attached to them. Human waste is stored in the black tank. 

The next vital part of the RV plumbing system is the water pump. Pumping water through the system requires a 12V pressure. Pumps prevent specific problems such as dripping water when using the toilet or shower. Additionally, it prevents water from rushing out of the lavatory and kitchen sinks. Since all plumbing systems depend on water pumps, a good unit is a lifesaver. 

How to maintain the RV plumbing system: Essential tips 

Utilize the right toilets and sinks in your kitchen 

It is impossible to live without the sink in an RV Plumbing System. There are several parts to the sink, such as sink covers and drains.  In order to prevent debris from building up in the pipeline, you must purchase a few sink accessories. Small stainless steel sinks for RVs are widely adaptable. They can be cleaned easily and installed directly. 

Many RVs have a sink stopper that can be raised or lowered to drain or fill the sink with water. If you have small children in your car, a traditional stopper will come in handy. Sink strainers for RVs catch even the smallest objects, such as grains of rice. However, straining the hair is also known to cause clogs. 

A sink mat might seem like something that you don't need, but it helps to properly drain the water. As a result, your valuable crockery won't break as well as clog up your sink. Consider putting on a sink cover in a multipurpose way if you're thinking of doing that. Several sink covers are available on the market. Furthermore, wooden chopping blocks or cutting boards can be used for RV sink cover replacements. This will save you space and keep your sink clean. 

RV and camper sinks for the kitchen and bathroom come in a wide array of styles and options. The utility sink is a whole new concept today. In addition to being used inside your RV, it can also be used outdoors while camping. Sinks from Bristol and Lippert are high-quality brands you can choose from, and these names have been making quality sinks for a long time. You should consider a lavatory sink if you have a space problem. These sinks are available in steel and plastic nowadays. The RV bathroom area can benefit from these corner sinks because they are space-saving and work well for bathrooms in the RV. Bathroom sinks provide both a stylish appearance and great utility. RV stainless steel sinks have safety glass lids, so when they are closed, they offer more working space. Dometic sinks are unique and popular because of their strong material and compact design. 

Watch out for your flushing system

It is important to remember that your RV toilet can only accept solid and liquid biological wastes, as well as disposable toilet paper. The RV toilet is not designed to handle the general household waste. This can cause problems with your black water tank, build up foul odors, and affect the natural biological cycle. Avoid using any other products other than the dissolving tissue. Keep your toilet system clear to prevent sudden plumbing problems. RV toilets are not as rugged as home toilets. Make sure you take good care of your bathroom so that you can use it for a long time. 

Check The Black Tank and Vent System Often

In order to maintain a smooth toilet and disposal system:

  1. Maintain the natural process of the black water tank. If you think the wastes need to break down, there are chemical products, especially for RV plumbing.

  2. You should avoid home plumbing products that can damage the plastic of your sink and result in permanent leaks.

  3. When it is necessary and allowed, drain your black water tank.

Additionally, please do not leave the black water tank open. During disposal, it can create entire solid wastes without liquid. Emptying the tank should never be rushed. 

It should be free of any problems. To avoid an unpleasant smell, however, you must check it frequently. It can lead to an unpleasant odor coming from the toilet. If you bottle up the air, the pressure becomes enormous. You can use your sewage vent to relieve the tension. A lot of filth can clog the ventilation systems of your RV. Sewer gas can be forced upwards, making using your toilet difficult. Additionally, it can interfere with the natural process and obstruct the plumbing system.

Maintain a sanitary RV water system

An important part of the RV plumbing system is keeping the tank clean and disinfected. Sanitizing and cleaning the plumbing system regularly will keep it in good working order. 

  • Deodorize your septic tank or septic system

  • Dispose of all freshwater and wastewater tanks, as well as your hot water heater

  • Your bathroom system's P-Trap should be cleaned

  • The damaged parts should be replaced with small pipings. You might need a plumber or essential plumbing tools for more extensive repairs like RV sink replacements.


You may not be able to detect a plumbing system issue during your vacation. Even new homeowners or campers can benefit from understanding how plumbing works. Know your plumbing system's tricks and tips, and you'll be able to maintain it confidently.
