Should An RV Water Pressure Regulator Be Adjusted While The Water Is Running Or Static

Question:

Do you adjust the screw when water is running through the hose ie: faucet is open, or do you adjust when all faucets are closed. Let’s say I want 55PSI, my current setup has 80 PSI when the hose has no water running though it all faucets closed-static and when I run the indoor shower for instance, I get 55PSI. is this the correct way to set it or is mine now set for 80PSI?

Hey Jeff,

You can adjust the Valterra Adjustable Water Regulator for RVs # A01-1117VP with the campground water running and the valves in the RV closed. The gauge shows outbound water pressure and not the pressure coming in. With the faucets open they would be letting off some pressure and you could accidentally overdo your adjustments. You want the static pressure to not exceed 60psi, otherwise your pipes or their joints could break and leak out.
