Re: RV water regulators

That's been our experience. We have a high-flow water pressure regulator that we purchased from Rick Dahl, "The Water Filter Guy" that goes onto the hydrant before our hose is hooked up. Then we have a gage on the other end of the hose. If the pressure on the gage is too high, even with the regulator, we either turn the faucet to restrict the flow or use the tank and our pump. We also have 3 in-line filters between the water source and the rig. I believe they help to dissipate some of the pressure. I could be wrong and I'm certain that I'll be duly corrected if I am. <g>


All that does reduce the pressure, while water is flowing. But if the
pressure rises after the flow is stopped, then you don't have a lot of
protection. Even reducing the flow will not reduce the static pressure
while it isn't flowing. And your system is at rest, not flowing, much
more of the time than flowing.

If the pressure is rising after the regulator with no flow, the
regulator is bad.

We saw that happen exactly once and we shut off the water and ordered another high-flow regulator from Rick. That one was 7 years old when it gave up the ghost. The current one is two, but doesn't get much use now. <g>
