If you’ve ever come face-to-face with water gushing out of your water hoses, pipes, or faucets, you know what kind of horrifying and frustrating damage severely high water pressure can do to your RV.
Getting the best RV water pressure regulator is considered a necessity in the life of an RVer.
In This Review, I’ll Cover 5 of the Best Water Pressure Regulators
What’s the Big Deal About Water Pressure Regulators?
Water pressure regulators are designed to regulate the PSI of the water coming out of a spigot. They keep the out-flow safe and consistent to ensure your plumbing is protected.
Often campsites have highly unpredictable water pressure that leave you to wonder each time you hook up if this is the time everything will go south. And I don’t mean palm trees and beaches…
Some places have been reported to produce water pressure up 120 PSI. This kind of pressure will tear your rig’s plumbing and give you extensive damage repair costs.
The purpose of water pressure regulators is to protect your RV’s plumbing from being utterly destroyed by these unreliable campsite water pressures.
It’s a little investment that can potentially save you extensive amounts of money.
Do You Need a Water Pressure Regulator?
Prior to hooking up your RV, you can use a water pressure gauge to determine how much water pressure is coming out of your water supply. You want the pressure to be consistently between 40-60 PSI.
If the PSI level is considerably higher, then YES!!! It’s strongly advised for you to attach a water pressure regulator.
You may be new to RVs or you may have been one of the lucky ones SO FAR who’ve been spared the devastating results of 120 PSI!
If you frequently hook up to various water sources, I highly recommend one of these little investments to keep your future free of disappointing damage.
How Much Pressure Should You Let Through?
Factories usually set their regulators at a default level of approximately 45 PSI.
Most homes are designed for 40-60 PSI. Some of the newer RVs are able to stand up to 80 PSI.
Anything higher than 80 PSI is considered dangerous for your RV Water hose, pipes, faucets, and even your washing machine. To be on the safe side, it’s recommended to keep the pressure around 50 PSI for a water flow that resembles your shower flow at home.
See below for some Water Pressure Tips and Tricks.
It’s not all about safety for your plumbing.
In some cases you want to consider how much water is in your water heater. A higher pressure will produce a higher flow rate and deplete your hot water supply faster than you had anticipated.
If you need to be efficient with your water supply, you may want to consider using a lower setting for a slower flow in order to save water.

Some water pressure regulators are simple brass or stainless steel devices that you attach to any standard garden hose and spigot fittings. These are fixed units that regulate water pressure at the default setting.
They may be simple, but many of these certainly do the trick. A couple downsides of these regulators are that you can’t see or adjust the PSI levels.
Other water pressure regulators come with a gauge that allows you to see how much water pressure is coming through the water line. You can adjust these with a screwdriver and set the water pressure at your desired PSI level.
With advanced technology and added benefits come more parts. These regulators with gauges pose the possibility of higher maintenance.
In all cases, you can choose to go with a fixed water pressure regulator at a low cost to see if it suits your needs; or you can opt to go for a higher investment for the convenience of a gauge and adjustability.
Let’s have a look at some options!

Sometimes the little things in life get ignored until the pressure gets too high and the lid blows off.
I wouldn’t want that to be the case for your RV.
Choose your water pressure regulator before your water system caves under the pressure of an unpredictably high water source.
