I replaced the water supply fitting in the outside wall of the trailer with what I think is a regulator ... appeared to be identical to the factory fitting ... do they come in different pressures?
I thought that the device which is usually built into the inlet fitting is only a check valve (so that the trailer's own pump doesn't pump water from its tank to outside; e.g. Aqua Pro models at Coast
), not a regulator
, although you can buy them with both features (e.g. SHURflo City Water Entry at Coast
). I have no idea how a 1983 Scamp
16' is equipped.
I use an in-line regulator with my Boler
, although I never did buy a pressure gauge to see if I need it. It is not adjustable, and the store where I bought it stocked only one version (i.e. one pressure setting). Every regulator I've seen is fixed, and set to something between 40 and 50 PSI, but I certainly haven't seen them all. I think if a fitting leaks
at 50 PSI, it just needs to be fixed, since that's a pretty common household water pressure.
A good idea from others in this forum is to use the regulator at the far end of the hose, where it is attached to the supply (rather than at the trailer end), so that the hose itself is also protected from excessive pressure.
