The Best RV Water Pressure Regulators With Leak-proof Design

Written by Stephen Ryan / Fact checked by William Turner

The best RV water pressure regulator is the ultimate solution if your goal is to keep the plumbing system of your recreational vehicle fully protected from uncontrollably high water pressures. Most RV owners are already aware of how high the water pressure in the campground can reach sometimes.

The problem is that this high water pressure, when transmitted to your RV, might cause damage to its plumbing system. In this case, you can use the water pressure regulator primarily made for recreational vehicles.

It is only a small device but you will find it extremely useful in maintaining a safe level of psi as far as the water that enters your vehicle is concerned. Note that while newer vehicles are capable of handling up to 100 psi of water pressure, it is still recommended for newer models to stick to around 60 psi.

For older recreational vehicles, however, it is beneficial to stick to 50 psi. Also, take note that there are campgrounds with a source of water that already regulates pressure. In that case, the regulator is unnecessary.

What to Look for When Buying an RV Water Pressure Regulator


The water system of your RV is one of the most vital aspects of ensuring that you will have a self-contained and satisfying camping adventure. With the help of this network composed of pipes, you no longer need to rely completely on communal kitchens and bathrooms each time you park at a campsite.

However, you also need to regulate the pressure in your water system to enjoy a better experience while on the road. In this case, you need the right RV water pressure regulator. What should you look for in your search for the best one? Here are just a couple of things that you have to look for:

Material – One thing that you have to check in an RV water pressure regulator is the material. If possible, look for a device made of brass because this material is known for its sturdiness, durability, and ability to resist harsh and harmful chemicals.

Ensure that the material is heavy-duty, too. It should be able to resist harsh elements, including rust, corrosion, and lead.

Gauge – Spend time examining the water pressure regulator’s gauge before buying. The gauge needs to be suitable for your specific requirements. A wise tip is to choose a regulator, which is capable of controlling a max water pressure of 50 psi.

Note that even if water pressure regulators are only small, these are extremely helpful in maintaining a safe psi level for the water pressure. Some RVs today use plumbing systems capable of handling a max of 100 psi water pressure.

Aside from the two items already mentioned, it is also necessary to look for an RV water pressure, which has the ability to decrease city water into a consistent and safe 40-50 psi operational pressure. In addition, it should be free of lead, making it safe for drinking water.

Other Important Factors to Consider


What is an RV Water Pressure Regulator?

A water pressure regulator installed in your recreational vehicle is helpful in lessening the water pressure, which comes into your pipes. It is capable of taking high-pressure municipal water that usually reaches up to 150 pounds per square inch (psi) then reduce such pressure into 50 to 80 psi.

Such is known to be a safer water pressure for your plumbing system. Remember that high water pressure can result in problems, such as bursting or broken pipes, running toilets, leaking sprinkler valves, dripping faucets, and costly damages to certain appliances, including your refrigerator, washing machine, dishwasher, and water heater.

The water pressure regulator in your RV is often located in the exact place where your primary water line is located and right after the primary shut-off valve. Such location makes it easier for you to shut the water main off immediately each time you need to change or work on the regulator.

Without the regulator, there is a great possibility for the strong water pressure to blast through your onboard fixtures and appliances. Several experts even recommend not going beyond 50 psi to increase your chances of lowering your water bills significantly and reducing water waste.

While the water pressure regulator is just a small device, it is extremely useful as it ensures that the psi of the water that goes into your recreational vehicle stays at a safe level. Remember that water pressure is quite tricky. If it is too low then it is greatly possible for you to take a shower with very light and unsatisfying trickles.

If it is too high then it is greatly possible for the water to come rocketing from your fixtures, causing their costly damage. You need an RV water pressure regulator to control the pressure of water that enters into your RV.

In most cases, it does such function with the help of a spring-loaded diaphragm, which you can adjust. The valve will then work once it constricts the water that enters into your RV and releases it based on your inputted settings.

How Does it Work?

The water pressure regulator primarily works by reducing the amount of water that gets through a pipe. Water forced through the pipes using extremely high pressure prior to the valve can be expected to slow down after the valve. It is a major help in ensuring that the pipes where the water passes through can lessen its risk of wear and tear.

It also prevents joints or fittings from being extremely pressured. Note that too much pressure on them might cause them to loosen up or leak. In most cases, the regulator also features an adjustable spring-loaded diaphragm. You can find it within the device, which aids in reducing the water pressure in the line inside the valve body.

You can expect the water that gets into the valve to be constricted. It is then released at a much lower pressure.

Types of RV Water Pressure Regulators

To choose the best one, you need to know exactly its various types. Here they are:

In-line barrel – This water pressure regulator is a great choice as it is offered at an inexpensive price. It is mainly designed to limit the water pressure in your RV at approximately 40 to 45 psi. One thing to take note of about the in-line barrel regulator is that it does not let you adjust the pressure.

Aside from decreasing city water pressure, it also restricts water flow. This might lead to a weaker shower flow and a weaker flow in your kitchen and bathroom sinks. Despite that, it still ensures that the water pressure in your recreational vehicle remains at a safe level.

In-line barrel high-flow water pressure regulator – This one is more expensive than the first discussed type of regulator. While it is not user-adjustable, it is still an excellent option because of its high flow rate. This can lead to a better flow of sink water and shower.

Adjustable water pressure regulator – This type often features a gauge, which is useful in monitoring the water pressure in your RV in a more effective manner. It is costlier than the other types.

One major benefit of this product is that you can easily adjust it to reduce or increase water pressure. The only thing you need to do to make adjustments to it is to use the screwdriver, which is often included in the purchase.

How to increase water pressure in an RV?

RV owners can use a booster pump to increase water pressure in their motorhomes. Some people might also use a water pressure regulator.

However, an RV pressure regulator only ensures water flow consistency by reducing the water pressure from a water distribution facility.

Although a regulator can increase water pressure, it will be useless if the low water pressure situation is in the RV park water utility. The following are other ways RV owners can increase water pressure in their motorhomes.

  1. Assess the water hose for kinks and bends and straighten them to increase water pressure to the RV.
  2. Check the RV water filter for signs of clogging or obstructions. Sediments and other particles can block the filter’s tiny holes, reducing the water pressure. It would be best to replace the filter element.
  3. Troubleshoot or replace a failing RV water pump. A failing pump can cause low water pressure problems.
  4. Check for leaks and fix them to increase the water pressure.

How do I know if it’s time to replace my RV water pressure regulator?

RV owners can look for the following signs to know if it is time to replace their travel trailer water pressure regulator.

  • Leaks from water fixtures – A failing regulator cannot reduce the water pressure from the RV park water supply, wearing out and cracking the faucet’s gaskets and other components and leading to leaks.
  • Water appliance damage due to high water pressure – Water heaters, water filters, dishwashers, washing machines, and other water appliances can only accommodate a narrow range of water pressure. Exceeding their pressure ratings can damage these devices.
  • Consistently low water pressure – Reduced water pressure can be a sign of a defective regulator valve. However, RV owners must also consider other causes of low or zero water pressure.
  • Banging or thumping noise in the RV water pipes – These unusual sounds occur because of undue stress on the water pipes.

Hammering noises and other off-putting sounds might not indicate a pressure regulator problem, but it is always worth checking out.

Do I need a water pressure regulator for my RV?

Yes, RV owners need a water pressure regulator for camper, motorhome, fifth wheel, travel trailer, or any RV type. RV parks and campgrounds have varying water pressures in their water supply, and RV plumbing systems can only handle 40 to 50 PSI, making them vulnerable to damage from any water pressure exceeding 60 PSI.

A pressure regulator safeguards the RV’s plumbing system and water appliances (i.e., water heaters, dishwashers, washing machines, and water filters) against high pressure-related wear and damage. These devices control the water flow, ensuring the pressure does not exceed the RV’s rating.

What are the different water pressure regulator types?

There are three types of water pressure regulators: standard in-line, high-flow in-line, and adjustable.

  1. Standard in-line – Their principal function is to regulate the water pressure to maintain the ideal 40 to 50 PSI levels.
  2. High-flow in-line – These regulators are similar to standard in-line water pressure regulators, except they facilitate increased water flow.
  3. Adjustable – As the name implies, these water pressure regulators allow users to change their water pressure settings with a simple twist of a tiny knob.

It empowers RV owners to control their RV’s water flow while referring to the built-in water pressure gauge. Unfortunately, these regulators are the most expensive.

It is mainly because the water pressure tends to change all throughout the day as the water consumption in the specific place you are staying fluctuates.

In this case, it would be best to seek the help of a professional plumber to assess it. You can also invest in a pressure gauge and use it to do your own test. It is essential to use the pressure gauge so you can constantly register around 40 to 60 psi. Because the flow of water varies, it might be necessary to do tests at various times every day.

Also, take note of certain signs of high water pressure, including frequent rupture of seals and gaskets found in your plumbing fixtures, hammering or banging sound when running water, especially when you’re doing the laundry or showering, leaking faucets, running toilets, and rushing water from your shower or faucets.

If you experienced the mentioned signs then it is greatly possible that the water pressure in your RV is too high. This might require you to invest in an RV water pressure regulator and use it by making adjustments to it based on what is necessary.

Once you find the unit, look for the external bolt, which typically comes with a locking nut. You have to loosen this locking nut as such will let you turn the bolt, thereby making it possible for you to adjust the water pressure. Now it is time to make adjustments on the water pressure.

What you have to do is to turn the pressure bolt or nut clockwise or counterclockwise depending on the specific water pressure you intend to get. You need to turn it clockwise if you want to increase water pressure and counterclockwise in case you wish to reduce it. Ask your partner to keep track of the water pressure when you are doing this step.

Once he tells you that the water pressure is already at 50 psi, what you have to do is to tighten the nut back up and you will all be set. By ensuring that your RV has the correct water pressure, you have an assurance that your plumbing system will continue working in good condition.

The right pressure will also be good for the environment as well as your wallet and appliances. By making just small and simple adjustments, you can expect your water pressure regulator to serve its purpose well for quite a long period of time.

How to install an RV water pressure regulator?

In some cases, the whole process of installing a water pressure regulator requires the help of a plumbing professional. This will guarantee professional results that will help keep track of the water pressure inside your RV. However, if you prefer doing the installation on your own then rest assured that it is doable by following some steps.

The first step is, of course, finding the most suitable water pressure regulator for your needs. Note that there are numerous products in this category, so spend time comparing your choices and figure out which one you can easily install in your vehicle. Once you have chosen your water pressure regulator, it is time to locate the pipes.

After that, the actual installation should come next. Turn off the water supply first then remove the pipes surrounding the pressure nipples that appear like triangular fittings found at the end of the pipes. Find the one, which allows the flow of clean water towards your recreational vehicle.

You should then use your wrench to unscrew the large fitting. Slide the regulator on the pipe in the sense that it is already inside it. After that, replace the pipe. After putting the ends of the pipe together again, let the pressure control valves fit in the area surrounding the new point.

Get a tape then wrap it around all the connections. The next step involves screwing the nipple back to the pipe. You can do that by using the wrench to tighten it. Once done, you can set your chosen water pressure regulator.

In case you invested in a more advanced unit then it might be necessary to turn it on first then program a certain amount prior to completing the installation process. Finally, close the ends of the pipe tightly. Turn on the water supply again. Examine whether there are leaks prior to refilling the hole.

You may also choose to use special plastic cuffs prior to rejoining the pipes. These cuffs are helpful in preventing leaks. Once done, allow the water to run from your faucet for approximately thirty minutes. This is necessary for completely cleaning the pipes before you start using them again.

What does the PSI in an RV water pressure regulator mean?

PSI, which is a term often used in RV water pressure regulators, stands for pound per square inch. It is mainly used to refer to the measurement of water pressure. It should be noted that municipal water often has a high pressure, which is measured up to 150 psi. If you want to stay safe then it would be best to lower it down to around 50 to 80 psi.
