5 Best RV Water Pressure Regulators and Why You Need One

Because RVs are always connecting to different water and power systems there are a few important pieces of equipment you need to protect your RV. A water or power source may not be working properly or within acceptable limits and can damage your equipment. This is why RV water pressure regulators are so important. You don’t want to wait until you’ve busted your water lines to discover that this is essential camping gear.

Let’s look at why an RV water pressure regulator is so crucial and suggest five of the best on the market!

What Is an RV Water Pressure Regulator? 

It’s not the best idea to just hook directly up to the water source. Water pressure varies by the campground and even by the campsite. If the pressure is too high, it can damage your RV pipes, which will be a costly repair.

We personally have visited RV parks where the water pressure was over 120 PSI! We found out because when we turned on the water the overpressure relief on our water heater blew out and our hose started leaking. Dont let this happen to you!

The answer is to get an RV water pressure regulator. Regulators are relatively inexpensive and provide peace of mind. They control and reduce water pressure coming inside your RV. Some limit the flow to a set psi, while you can change others to fit your desired psi.

What Are the Benefits of a Water Pressure Regulator? 

High water pressure will bust your RV pipes. They’re delicate, and since water pressure varies so much from one location to another, a substantial increase in pressure can lead to water leaks and expensive repairs. Spending $15-30 is much better than spending hundreds, especially when it’s in your power to prevent damage.

If you get a regulator with a gauge, you can vary the psi. Maybe you want to increase the pressure slightly to take a shower and then reduce it for the rest of the day. As long as you’re within a safe limit, a regulator with a gauge can give you added water pressure when you want it.

Gauge vs. Non-Gauge Regulators

There are two RV water pressure regulators: ones with a gauge and ones without a gauge. Regulators with a gauge allow users to change the psi to the desired pressure. Some RVs can withstand higher pressure than others. Regulators with a gauge are easy to change with a screwdriver. Regulators without a gauge have a standard set limit that you can’t change. They limit water flow from the source to your RV.

Do You Have to Have a Water Pressure Regulator?

Some campgrounds require you to have an RV water pressure regulator. They may have a high psi and don’t want to be liable for damage to RV lines. If this is the case, the ranger will let you know upon check-in that you must have a regulator. You might not be able to hook up to the water source if you don’t.

However, most campgrounds don’t require an RV water pressure regulator. Still, it’s a good idea to have one. Surge protectors aren’t a requirement either, but you certainly want to protect your RV circuits. An RV water pressure regulator is an item you definitely want to add to your camping gear and use every time you hook up, whether it’s a requirement or not.

Is a Water Pressure Regulator Worth It?

It’s essential to add an RV water pressure regulator to your camping arsenal. Even though it’s not a requirement to set up at campsites, it’s worth $15-30 to protect your pipes from bursting. It’s a cheap insurance plan for RVers. Plus, when the water flow is too little, you can increase it to take nice, hot showers in your rig rather than taking a walk to the bathhouse.

If you haven’t picked up an RV water pressure regulator yet, don’t wait any longer. Get one with a gauge or without a gauge, but don’t risk the potential damage to your RV.

We have the Camco non adjustable one. We stopped using it because it reduced the pressure too much. We will be upgrading to an adjustable one.
