Water Regulaters in Motor Home

Don, they have some good stuff on that page, but, the very top item "Fairview 55psi inline regulator", that one is a "calibrated hole"

Here's what you need...Water Regulator. The ones shown, further down the page, with the pressure gauge will let you know what the pressure is and what you have it set at.

Mine is mounted in the water bay. My power water hose reel and hose is rated to 150 psi.

RV.Net Poster WNY Pat sent me info on this a long time ago. Go to the rvwaterstore.com website. One of there most popular valves is the Watts #263-A. Investing in the stainless steel model would be a wise choice over the brass! The RV Store recommends that you set your valve to 60-65 psi to provide a very nice operating system.

e thing that has been "danced about" here but not really emphasized is, a calibrated "hole" is not a pressure regulator, it is simply a flow restrictor.

The vast majority of socalled pressure regulators are just calibrated holes.
they work because the hole is smaller than your faucet valves, so they become the restriction only when you are actually using water.

As was stated above, when no water is flowing, the pressure in the pipes will equalize.

A Watts type regulator is a real regulator. the water pushes against an adjustable spring which regulates the pressure, not the flow.. They have a "dome" sticking out, and a T adjuster on the end of it. They coost like fifty bucks.

Those "regulators" in camping world that cost ten bucks and look like a short peice of pipe, those are just holes. They do nothing but restrict the flow to your shower

Personally seen water pouring out of 3 RVs over the years.

You guessed it NO regulator. 2 were toilet valves that burst. The other was a high end motor home and a fitting failed at the water heater connection. Water was pouring out everywhere. I would bet that there was not a square inch of flooring dry in the whole unit. That park had 65 psi on my gauge. My wife alerted the owners that were 3 sites down.
Site was flooded as well hundreds of gallons for sure.

Pogoil.

My 1998 old clunker came with a plumbed in watts pressure reducing valve.

I also have mine set at 55 the park pressure here is 80. All hookups are tagged with a high pressure warning.

Probably you do have a regulator, but that protects your coach and not the hose. I took mine out and only use a Watts regulator at the campground supply. Without this regulator I was parked where the water pressure was in excess of 125 pounds and didn't know it. We left and a neighbor shut off the faucet after my hose split sending water over the top of the coach.

When you select a Watts regulator get the largest inlet and outlet that you can easily adapt to hose connections. The flow (amount of water passed through) will be greater than using small connections. The pressure can be controlled with either. I use an adjustable one set at 55 pounds.

I have a pressure regulator but when I use it I get very little pressure from the faucets, so I stopped using it. Does that mean I have a built in regulator?
would it decrease the pressure that much going through two regulators? Without the regulator I get about as much pressure as my fellow camper who is using a regulator. I'm confused.

It only takes one time to see water running out of every crack in your motorhome to get on board with a pressure regulator.

In my case, it was not even campground pressure related! A crimp fitting popped loose on the toilet supply line. My water pump pumped my fresh water tank dry all over the inside of the coach. I rarely hook up to city water, even when in the campground. But, as another cautious posted suggested, I make certain both water pump switches are off before we leave the rig for any length of time.
