water pressure

What should the incoming water pressure be for my Thor ACE 29.3

Probably under 60 psi. They make water regulators for this.

Agree: there's no reason for anything higher than that.
(50 to 55 psi is my preferred range...)

I set my pressure regulator to 55 psi. Would not recommend anything above that for the motor home plumbing.

I never care what the pressure is.
I use my storage tank and rv pump exclusively.
I see no reason to torment myself with high or low shore pressures being different at every rv site.
I do have a regulator because there's no reason to not have a regulator.
But
If the shore pressure is 15psi or 150psi, I remain unaffected by water heater and reverse osmosis and kitchen sink variances.

I just use a pressure regulator. It screws right inline with the hose. It’s cheap insurance to prevent issues.

On our prior 2015 Challenger the Owner's Manual stated 55 PSI was max pressure and the Anderson Kantleak system stated 100PSI was max for the valves and fittings. That owners manual was the generic Class A and Class C Thor manual.

My current coach recommends 45 PSI. I have and use an adjustable pressure regulator set at 50 PSI.

I have both kinds of regulators, a fixed pressure of 50 PSI and an adjustable one I have set at 55 PSI. At some campgrounds the spigots are placed where there is hook up issue
with the larger adjustable regulator.
Safe travels and stay safe in these difficult time in both or our countries.

From about 40 psi, but no higher that 55psi.

I do the same thing. I prefer the consistency of pumping my own out of my own tank at all times. One less thing to connect/disconnect at the destination.


Side benefit (for my rig) is that I know when the fresh water tank is nearing empty, the gray waste tank is nearing full. Handy because the gray water tank gauge is notoriously inaccurate but the fresh water tank gauge is spot on.
