Best RV Water Pressure Regulator Buying Guide

What to Look for in an RV Water Pressure Regulator

Finally, you’ve listened to reason and decided to purchase an RV Water Pressure Regulator to get the most out of your motorhome. Yet with the variety of products out there, how do you distinguish between the flimsy and the fabulous? Ask yourself these three questions before choosing your trusty RV buddy and you’ll experience stellar water pressure like never before:


Legally, your water pressure regulator must contain a weighted average lead content of less than 0.25%. That’s why all the best brands out there back regulators that are 100% lead-free.

Brass Materials

Don’t opt for a regulator manufactured from unsustainable material that will be out of action only after a few trips. All the most reliable water pressure regulators are made from rust-resistant, durable brass.

PSI Compatibility

Check on the label to ensure that your potential RV water pressure regulator is compatible with all US water sources. It would be a real shame to purchase your chosen product only to find out that it didn’t fit your RV system!

Water Pressure Regulator
In some cases, a water pressure regulator is more than just a useful tool — it’s a necessity.

Why You Should Use a Water Pressure Regulator

It’s An Investment For The Long Term

Do you know what’s more expensive than a water pressure regulator? Replacing your RV’s pipes! Not only will using a water pressure regulator grant you the peace of mind you deserve while exploring the great outdoors, but it will also protect your pipes from bursting and prevent untold amounts of damage to your RV.

Your Water Will Be Purified

Now you’ll know that the water you and your family are drinking from is high-quality and safe through and through.

Regulate Water Pressure

Control. It’s what every holidaymaker claims they don’t need, but they all crave. And being able to set your water to the pressure you desire is a way to obtain that control on your holidays.

Types of RV Water Pressure Regulators

In-Line Barrel Type

This kind of water pressure regulator is ideal for first-time campers who want a steady yet controlled water pressure, usually around the 40-45 PSI mark. Although they give an RVer stability, they’re often the cause of weak water pressure!

In-line Barrel Type High Flow

Being more expensive than the in-line barrel water pressure regulators, the high flow models deliver by granting an RVer with, obviously, higher water pressure and stronger flow (but you probably would have guessed that without our help!).


Last but certainly not least, adjustable water pressure regulators are every happy camper’s dream. They’re undeniably the most expensive out of all types of regulators but allow their users to change the water pressure to how they see fit. An attached gauge is usually included to make this process easier.

How to Install an RV Water Pressure Regulator

The best way for RVers to make the most out of their water pressure regulator is to attach it straight to the campground’s water supply rather than your RV’s. This will protect your hose and RV pipes from bursting and encourage superior water flow at the same time.

Best RV Water Pressure Regulator FAQ:

Q: What is an RV water pressure regulator?

All RVers should own an RV water pressure regulator. This is a valve that reduces the water pressure emerging from the main water source to a controllable and regulated level before it even arrives in your RV.

Q: How does it work?

Water pressure regulators aren’t as simplistic as they look. In a few stages, we’ll attempt to explain how these invaluable devices actually work. Bear with us…

  • Step 1: Activation — As soon as water makes its way through the inlet end of the regulator and around the flow area, the pressure regulator is activated.
  • Step 2: Here Comes the Water! — As soon as the water enters the throttling stem (which is part of the main cylinder) the spring holds the flow area open, thereby allowing the water to enter.
  • Step 3: Regulating the Flow — So, what actually happens when the water pressure is too high? This high pressure will trigger the diaphragm inside the regulator which will subsequently begin to close the flow area. However, this area won’t be closed off entirely – only enough to control a set pressure and flow. And one of the handy things about RV water pressure regulators is that they’ll never exceed the manufacturer’s operating pressure range, therefore keeping your RV’s pipes burst-free!

Oceanside Camping

Water pressure regulators are particularly useful for RVers.

Q: What is the ideal water pressure for an RV?

According to, the ideal water pressure for an RV may vary depending on the model of RV that you have, as well as the age of your RV’s plumbing system. While some modern RVs are able to handle pressure as high as 100 PSI, most experts don’t recommend letting your pressure get past 60 PSI, with an ideal pressure being 40-50 PSI.

Q: How can I check my water pressure without a gauge?

Waterbrowser outlines several simple and quick ways to check your water pressure without using a gauge. In one of the better methods, you need a water hose and a tape measure. Connect your water hose to one of your water faucets and turn the faucet on. Raise the hose up as high as possible until water stops coming out of the hose. Use the measuring tape to measure the elevation between the hose and the faucet in feet. To convert your water pressure from feet to PSI, divide the number of feet by 2.31.

Q: How to adjust an RV water pressure regulator?

If you own a high-quality RV water pressure regulator, adjusting it to suit your needs should be easy as pie. When arriving at the campground, simply connect your pressure regulator to the water supply and connect your drinking water hose to it. Next, take a flathead screwdriver to turn the behind screw (turn clockwise to obtain a higher pressure) to allow for superior water flow into your RV. Remember; settings above 60 PSI are not recommended!

Q: What does PSI stand for?

Standing for pounds per square inch, PSI is a measurement of pressure. If this unit of measurement runs too high, then you’re running the risk of bursting the freshwater pipes in your RV – leading to a very costly repair. To be on the safe side, it’s best to keep the water pressure in your RV around 50-60 PSI.

Our Top Pick

So, out of all the commendable water pressure regulators reviewed for you today, which of them would we trust to bring praiseworthy water pressure into our own RVs?

They’re even offering customers information concerning lead testing of specific batches. We commend transparency in a marketplace full of con artists, and it’s evident that Renator is sincere through and through.
