water pressure regulater
Purchasing our first RV and we are looking on Amazon for accessories. Just wondering what the max water pressure was for a typical RV? Should I buy the cheap one that allows 40 to 50 pounds of pressur...

Here is latest water mess...
Curious - where did you read that? I thought it was tested much higher like 90 or 100 psi. Maybe they test at 55 but should be able to withstand much higher. I have our Watts regulator adjusted to 60 psi upon the recommendation of RVwaterfilterstore. Pex, pinch clamps, fittings and faucets should be good for at least 100 psi.
CG water pressure can get pretty high sometimes and I've read as high as 200 psi. We had 120 psi somewhere this season. If you don't use a regulator sooner or later you could have a big problem on your hands.
The low cost inline regulators aren't really regulators and are just a flow restrictor and all they have is a small diameter orifice inside. Pressure will equalize on both sides in a static state. I am going to make up a demo setup in the near future to demonstrate this. A "real" regulator like a Watts is the only way to go.
I doubt that RV's are all factory tested with high water pressure or even tested at all. The delivering dealer probably tested the water system at whatever his line pressure is.
The inline (tubular shaped) pressure regulators should work in theory. They are not just a flow restriction device, but have a spring-loaded valve inside. That valve should prevent pressures only as high as the spring allows. The problems are that they are cheaply made allowing leakage thru the valve and the design allows little opening at certain pressures and flow levels.
Gil, if you do some testing, try various pressures and flow requirements. I did some rudimentary testing and found some unexpected results.
