If you want to keep your RV plumbing in good working order, you need a water pressure regulator. RV veterans know that surges in water pressure at RV parks are a common occurrence, and those surges can cause expensive damage to your plumbing.

Worse still, plumbing damage can result in the worst case scenario for any RV owner: unseen water damage and mold.

What’s the solution? A water pressure regulator for your RV. Newer RVs can handle up to 100-psi water pressure easily, but experts recommend maintaining your water pressure at 60-psi to ensure your plumbing isn’t under undue stress.

Choosing the right water pressure regulator for your RV is an important decision. To make that decision easier, check out our reviews and buyers guide to get the water pressure regulator that best meets your needs.

BUYER’S GUIDE

What are the best RV water pressure regulator brands?

Renator and Trumeter are probably the best known, but Camco and Kozyvacu both have excellent reputations as well.

How do I use the water pressure regulator for my RV?

You need to use a short hose to connect it to your RV’s clean water intake, then connect the host from the water source to the intake port on the regulator.

How do I adjust my RV’s water pressure using the regulator?

Most RV water pressure regulators have an adjustment knob on the top with preset pressures. Loosen the screw and twist the knob to the desired pressure. Do not exceed 60-psi.

How to install a water pressure regulator for my RV?

There is a process you need to follow to install the regulator correctly without damaging your RV’s plumbing:

1. Begin by connecting the water source to the regulator intake.
2. Connect the shorter hose that will connect to your RV to the regulator output. Do not connect this hose to your RV at this time.
3. Turn on the water source to flush any air out of the regulator and hose. Turn off the water supply.
4. Connect the output hose from the regulator to your RV clean water intake, then turn the water supply back on.
5. Turn on all RV water fixtures (including flush toilets) to flush any air out of the RV’s plumbing. Turn fixtures off before proceeding to the next step.
6. Adjust the regulator with the regulator screw to the desired pressure. The preset is usually 45, but it should be set under 60.

Once the regulator gauge reads the desired pressure, you’re good to go.

What does the PSI reading on an RV water pressure regulator mean?

It represents the pound-force per square inch (psi) of water pressure currently flowing through the regulator. Ideally, your water pressure should not exceed 60 psi to prevent damage to your RVs plumbing.

Is a water pressure regulator necessary for RV?

Yes. It is highly recommended to have one installed in your water line. Water pressure regulators make sure a water pump gets the appropriate amount of water to operate correctly. Without a pressure regulator, the water pump could be damaged.

How much water pressure can my RV handle?

40-50 psi. But it may also vary depending on the condition of your RV’s plumbing system. Most modern RVs can handle up to 100psi of water pressure. But experts recommend not to let the water pressure exceed 60 psi. 40-50 is ideal for many. 

CONCLUSION

Of these five regulators, the Renator M11-0660R is my first choice. It’s got the best construction materials, excellent drinking water safety certifications and an exceptional track record for both reliability and quality. You need a pressure regulator to protect your RVs plumbing, and the Renator M11-0660R is going to last the longest and give you the best value for your money.
