In order to keep your RV plumbing system working correctly and protected from high water pressure, you need to invest in the best RV water pressure regulator. I find that some campgrounds can have incredibly high water pressure, which can easily damage an RV if you’re not prepared, which is why investing in a great regulator is so important.

How to Choose the Best RV Water Pressure Regulator

There are two main types of water pressure regulators that you can use on your RV: adjustable and non-adjustable. Non-adjustable water pressure regulators simply adjust the water pressure coming into your RV to a single pressure and you can’t change it.

I prefer adjustable water pressure regulators, as you can easily change the water pressure if you need to and you will be protected from inconsistent water flow at the campground. When you opt for an adjustable water pressure regulator, you can adjust your water pressure to make sure that it meets your needs, no matter whether you are showering, washing dishes, or simply running water for drinking.

Always make sure that you choose a water pressure regulator that allows you to check the pressure of the water coming into your RV. The problem with non-adjustable regulators is that they don’t have a gauge, which means that you can’t easily check the pressure.

Water Pressure Regulator for RV’s Benefits

Water pressure regulators are incredibly important to have when staying at an RV campground, as you never know what the water pressure will be. When you have water pressure that is too high coming in to your RV, you can easily damage your pipes and plumbing.

Using a water pressure regulator allows you to adjust the pressure from your water source before it gets into your plumbing. Generally, this means that it will lower the pressure, thus preventing your pipes from becoming overwhelmed and bursting.

One main problem that RV owners often run into when they are at a campground is that their RV can only handle water pressure up to a certain psi and the water from the campground is often at a higher pressure. Since water pressure at a campground can fluctuate so widely during the day as others use water, using a regulator is the only way to ensure that you protect your plumbing system and get the pressure you need.

Without a regulator, you put yourself at risk of not only bursting your pipes but also causing slow leaks and loosening connections in your plumbing. While these problems may not be apparent right away, they can cause major problems in the future.

Attributes to Look For

I think that one of the most important things to consider when shopping for a water pressure regulator is the material the regulator is made out of. Brass is becoming more and more common, which is great, as these regulators are designed to resist rusting and are much sturdier than plastic regulators.

Additionally, look for a regulator that has an explosion-proof plug. These are designed to resist the shock of water pressure that exceeds the capacity of the regulator and won’t easily break. They can prevent water from spraying out of the end of the hose.

Another great attribute to look for is how easily you can adjust the regulator. Some allow for screwdriver adjustment, which makes it quick and easy to adjust the desired pressure and allows RVers to quickly rectify any problems that they are experiencing.

How to Use Your RV Water Pressure Regulator

When you are ready to connect your new regulator, you first need to connect it to the available water and then to your RV’s plumbing. It’s important that you know how to set your desired psi before connecting the regulator and letting water run through it.

I recommend checking the psi of your water source and then adjusting your water pressure regulator to meet your needs. Most of the time, RVs can only handle around 45 psi, although there are some newer ones that are able to withstand a higher psi.

Once the regulator is set and installed, it’s a good idea to check it every once in a while to make sure that it is still working the way that it should. This gives you peace of mind that you won’t run into any problems.

Where to Put Your Water Pressure Regulator

You can attach your Rv water pressure regulator at the spigot or at the coach end of the filter. If possible I always connect it at the spigot.


One of the biggest mistakes that some people make when using an RV water pressure regulator is they don’t attach it to their water source before attaching it to their RV. This can cause major problems and can even burst your connecting hose if there is very high water pressure. You always want to attach the regulator to the water source first.
