Water Regulaters in Motor Home

FYI, that method doesn't adjust the pressure, only the flow rate. As soon as your water usage ceases, the pressure in the coach lines will rise to park feed line pressure.

A couple of years ago we we at a park that had a malfunction at the well head pump that caused the line pressure to spike to some very high number. The result was almost every water hose in the park bubbled and/or burst as did the lines in the clubhouse. Some coaches without a regulator suffered internal leaks from lines and/or fittings.

Well, thank you bluwtr49 and a few others, guess I learned another valuable lesson even though my little brain isn't understanding all this. Sure seems to me that if the the water is not coming out full blast then the pressure should not be too strong inside the coach. But I guess I'm wrong. Thanks.

I was at a CG a few years back, and before I bought a regulator, that had water running out the MH when we got back. They had over 100 PSI and mine wasn't the only one with water running out.

This is a common OEM inlet with built in pressure regulation.

ShurFlo

Our first coach had one set of 45 psi, the later versions are set at 65 psi. If you have an entry like this than you have pressure regulation....not saying other coaches may not have something different but these are fairly common.

Added regulator. Not too bad a job and peace of mind. I do recall reading somewhere that if the water is on no matter how low in initial flow, the pressure will build up when the lines fill and that is when the fittings/lines/equipment fail. When we leave for the day and each night, I turn off the water and use the pump. Guess I am overly cautious.

Good morning. Yah that won't work. If the pressure is 80 PSI on the line and you turn it down till its just dripping out, once the lines are filled and pressured the pressure will be 80 PSI anywhere in the motorhome. Just a heads up.

AND, you are restricting the flow of water to the RV. Doug

Some do, Some do not.. I suggest you get a Does not.

The place for the pressure regulator is at the PARK END of the water hose.. I have seen parks (Stay in on in fact) that warns you of pressures over 110 PSI and one forum member (not sure which set of forums) claims he's under a lot of pressure here... His gauge shows 125

At those pressures...... Your hose can do a Cartoon Special (Blow up).

PLUS the Sur-Flo regulator they use.. I give it a 9 when new dropping with age (I have one, but it's an external) The Watts and Zurin models I have get a 10 when new and are easily rebuilt.. I think the sur-flo can be rebulit too.

I like the Watts and Zurin mnodels Bell shaped housing, 1/2 inch or largr bore. Mine are both 3/4 inch (Which is often less expensive).

Not sure why these are even needed anymore on newer coaches. The new pex tubing used on MH's can withstand far more pressure than a CG supply can provide. I am sure there will be a slew of responses stating otherwise. But I don't use one.

Before they had PEX they used COPPER. WHICH do think would hold pressure better:) As to regulators, the RV's are designed and must be able to withstand at least 100 psi. IF you have water pressure in excess of 75 psi at the CG, that would be amazing. The pressure is not about the tubing, but about the fittings and the various appliances(water solenoids) connected to the water system. Doug
