RV Water Pressure Regulator

Protecting Your RV From High Water Pressure

Some time ago, we were in an RV park with extremely high water pressure.  I found a puddle of water in our bathroom floor from the toilet leaking, and immediately shut off the water supply and switched over to the fresh water tank.  This made me very concerned about damage to my plumbing. 

The next day I bought a gauge and checked the water pressure at our hose bib.  I was amazed to find it very high, around 100 psi.  That's too high for most plumbing, even in your stick-built home.  I imagined coming home to an RV with an inch of water in the floor, and I really started watching the water pressure at parks.  You can get excessive water pressure anytime, but most often it's at a park that's nearly empty off season, or even at a full park at night, when nobody is using the water -- it can go up to extreme levels! 

So I bought one of those little water pressure regulators at Camping World.  You know the kind I'm talking about, here are a few photos of typical ones:

Well, I discovered quickly that I'd wasted my money.  These are really junk.  They do only a fair job of reducing pressure, and because the opening inside is so small (about 1/4 inch) you can't take a decent shower! 

I started looking for a professional water pressure regulator, also called a water pressure reducing valve, like you'd find in a house.  "Watts" is a well known brand.  At the RV show in Redmond, Oregon I found a Watts water pressure regulator with a gauge.  It's adjustable too if needed, and it does a great job of regulating and reducing the pressure to around 50psi.  Installation was easy, as you can see in the photos below.

If you don't already have a water pressure regulator, I highly recommend that you get one soon.  At $40 or so, it's some of the best insurance you can buy!  No RV should be without one.  Remember, your stick-built house just sits there in the same spot all the time, so it either needs a reducing valve (and has one) or it doesn't.  However, your RV moves to a different hookup how many times a year?  OK, I'll shut up now -- but don't say I didn't warn you!
