came with the camper in the box of Camco goodies they give you. Most of initial camping was in MO State Parks where we did not have water hook-up so running off the 12v pump.
What I have noticed is that when I do have full hook-up there is LESS pressure when running city water through the regulator pictured above.
I don't really want to trust my inside PEX tubing to my ability to adjust the water pressure at the city tap, but the little piece of blue plastic does not induce much confidence either.
Curious what others have used.
I quit using them years ago, they all work by restriction, needed or not. Cuts water pressure and flow to all high volume uses.
Specs:Pex tubing can easily handle in excess of 100 psi.
Normal water pressure in City Water systems all over the land other than in ground pump is 50-60 psi max. Its set by the water towers you've seen everywhere with town names on them. Height is constant so is pressure output. Most campgrounds provide maybe 40 psi service.
The water heater relief valve on outside access are set by factory to al least 125psi opening pressure. That is the only system relief available in any RV.
Why speed 20-90 bucks for something that is really clever marketing by RV supply houses?
BTW older systems of plastic pipe is safe to 400 psi cold and 125 psi hot (180F).
Like I've said, haven't used one in years, never saw a plumbing failure due to high shore pressure, have you?
