Water Regulaters in Motor Home

I don't use them, I just adjust the water pressure at the water spigot . I just turn the handle until it looks and feels okay.

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.
