What is an RV Water Pressure Regulator?

An RV water pressure regulator is not the most exciting or interesting purchasing decision you’ll ever make regarding your rig. That said, its equally as important as your GPS, radiator cap, surge protector, or anything else.

A good RV water pressure regular that does its job, and does it well, will reduce water pressure and protect your RV’s hoses, connectors, and plumbing.

Not only will it keep your water systems clean from elements but will keep it lead-free as well. An RV water pressure regulator can also prolong the lifespan of your RVs equipment and plumbing.

These units will create, or convert, water-flow into a 40 to 60 PSI stream (depending on the age and size of your rig). Fifty PSI is generally considered the sweet spot where RV water pressure is concerned.

Why Do You Need an RV Water Pressure Regulator?

The reason you need a water pressure regulator is so you don’t create a leak in the plumbing pipes or fixtures in your RV. The plumbing in your RV is made to handle water pressures up to about 60 psi. And sometimes the water pressure from the water faucet at your campsite is more than that which can cause the plumbing pipes or fixtures in your RV to leak.

Trying to adjust the valve and guessing what the water pressure is just doesn’t work and if you guess wrong you could over pressurize the plumbing system and cause a leak.

A water pressure regulator allows you to make sure that the pressure of the water entering your RV is set to somewhere between 40 – 50 psi so you don’t blow out your plumbing lines.

Need more proof that you need a water pressure regulator? Take a look at the house you live in. Almost every home across the country has a water pressure regulator. This ensures that the plumbing pipes and fixtures aren’t over-pressurized which will eventually result in a leak.

So water pressure regulators are an absolute necessity at home and in your RV too!

Better water pressure regulators are adjustable and allow you to set the pressure. Inexpensive RV water pressure regulators are not adjustable and they are typically set at 40 psi. They are better than nothing but you can’t adjust these types of pressure regulators.


6 Things to Consider Before Buying an RV Water Pressure Regulator?

Before we move on to the list of individual RV water pressure regulators that we picked out, there are a few important considerations to factor in:

1. Size of Connector

Although most RV water pressure regulators, today are manufactured with a 3/4-inch connection size, that is not always the case. Before picking out a connector for your rig, make sure that you check the manual or old regulator itself for the precise size needed.

Some RV water pressure regulators may come with 1/2-inch threads or even odder sizes than that. However, this won’t typically be the case. IT doesn’t, however, hurt to check first!

2. Gauge

The best RV water pressure regulators come with built-in gauges that let you keep an eye on the PSI level of your RV’s water system. Most gauges have a readout of up to 100 PSI. That said, for the most part, RVs only require about 50 PSI.

There are also RV water pressure regulators without gauges at all. These are sometimes excellent products, but many times end up being replaced anyhow due to not having a gauge. Avoid purchasing a pressure gauge next season by purchasing an RV water pressure regulator with a built-in gauge.

3. Quality of Materials

The name brand normally says a lot about a product. However, sometimes, a great product is produced by a little known manufacturer. That’s why it’s never wise to judge a book by its cover.

Take a look at each RV water pressure regulator that you’re interested in and the quality of materials used in its construction. Does it appear to e high-quality? Do you think it will last a long time?

How about warranties or guarantees? If one or the other isn’t included with your purchases, this may be an indicator that the item is produced with sub-par materials or craftsmanship.

High-grade metals such as bronze and high-duty ABS plastics are a couple of the primary materials used in the best RV water pressure regulators.

4. Ease of Use

The ease with which you can operate or otherwise utilize something is a great indicator of its value. Likewise, if a product is hard for you to understand or operate, the lower its value it is (if it is not beneficial, it is a hindrance).

Take the time to look over the regulators you’re considering purchasing to gauge how hard or easy they will be to use. Ask a store employee or read reviews for first-hand opinions of the products.

5. Type of Regulator

Today there are three main types of RV water pressure regulators in use (I’m sure more exist, these are just the most popular – that we know about).

Here they are:

Standard In-line Barrel Water Pressure Regulator

These types of RV water pressure regulators are among the most popular. This is due to their basic design and inexpensiveness. The main function of the in-line barrel type RV water pressure regulator is to reduce/increase the water pressure in your rig to roughly 40 to 50 PSI.

In-line Barrel High-Flow Water Pressure Regulator

The in-line barrel high-flow water pressure regulator is a suped-up version of the previous version we discussed (the standard in-line barrel)

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

The third type of RV water pressure regulator is the adjustable sort. This version typically includes a built-in water pressure gauge for actively monitoring water-flow levels throughout your RV.

This is the type we use and we highly recommend you buy an adjustable pressure regulator. This way you have control over the amount of water flow.

As far as costs are concerned, the adjustable water pressure regulator is a bit more expensive than either of the in-line sorts. That said, they are also much more versatile (requiring little more than a screwdriver to make adjustments to your water pressure).

6. Overall Cost

As with most major purchases, the cost is one of the biggest considerations of all. Many times it is the very factor that determines which product we end up with, due to the budget available.

With RV water pressure regulators, the initial cost is pretty much it. There is little to no maintenance involved and no additional purchases necessary either.

Keep in mind that you should only have to make this purchase once or twice in an entire lifetime. Make it worth your money when you do make the buy.

Installing this simple piece onto your RVs currently existing plumbing system will protect your pipes by keeping your water-flow well-regulated.

The regulator features a standard fitting 3/4-inch threaded connector of a longlasting and simple lead-free brass design. It also has a built-in gauge for monitoring your RVs’ active water pressure.

The unit comes highly recommended for doing a good job. However, it doesn’t really have much going for it in regards to any competitive edges and it comes with a hefty price.


  • 3/4-inch rust-resistant connector
