Water pressure regulator

Does a water pressure regulator always restrict the pressure of the water coming into the trailer, or does it only restrict it when the water pressure at the campground is too high?

I think the answer is basically "yes". Standard restrictors are preset to about 45psi. The setting doesn't change but it doesn't really restrict until the incoming psi exceeds the setting. Same for the adjustable type (recommended). Ours is set to about 50psi, but if incoming psi is only 35 then we get 35psi.

It's always wise to use a restrictor for "just in case". Many parks have pressure well north of 50psi.

You do not want to use the cheap “restrictors”, but should use a proper regulator. A regulator will not obstruct the flow of water but the cheap so called regulators that only restrict flow will reduce flow. We use a heavy duty Watts regulator, but an adjustable regulator should do the job. This is one that should work fine. https://a.co/d/aggo0ts

This sounds like it will do the trick for us. Thanks.

Here is an option for you, and it resolved my concerns over using a pressure regulator.

To begin, I do have an adjustable regulator, it is not as expensive as replacing a line that burst due to high water pressure.

Anyhow, after one waterline leak and a broken hose, where my trailer flooded and the leak was not found until I saw/stepped into a water puddle, I have decided to run water for the rig through the tank/water pump. That way I can hear if a line breaks - when we leave the trailer the water pump is turned off. Since employing this method, I had another leak in the bathroom - faulty toilet valve, and my external hose failed. Both times I heard the water pump start up and found the leaks shortly thereafter!

I do carry an extra water pump with me.
