Water Pressure

Question regarding water pressure in the rig. Is there a built in regulator? If not, what is a good pressure to set a regulator on? I have a regulator but I think it is 40 psi and I get low pressure in the coach? What is a good pressure without risk of blowing a line?

RV plumbing is PEX....good for 100 psi
Fittings not so much!



When I used a regulator it was set for 50# Static (no flow)


But stopped using City Water connection except to fill fresh water tank
Use pump which provides consistent pressure/flow regardless of where we go.


Low pressure...city water

Clogged regulator
Clogged City Water Inlet screen or check valve
Clogged water filter


So you get same low pressure if using pump?

Pump doesn’t put out much if showering.

Not a lot of pressure but usable. If I use a 60PSI regulator will I be safe?

No problems with 60 psi. Get yourself a good Watts regulator and you will never have to worry about it again. Also popular are the small brass regulators that incorporate a pressure gauge and hose fittings.

60 psi will be fine. I have my well set to run 40 60 psi and have had no problems. What you have to watch for is city water connects that spike at night to 120 psi due to non use. RV pumps are factory set to 40 45psi static shut off but seldom deliver that much when running. Best solution for pump problems is a 3 gallon amtrol pressure tank. Gives you a true 40 psi when running and makes the pump last longer.

We have a Watts with gauge. It’s built into the line feeding the water hose reel and is set for 60lbs. This is the second coach with this gauge and it works perfectly.
I keep a cheap brass regulator as a backup just in case but these small ones use a restriction to limit the pressure, thus, not much flow.

I bought a household one at Home Depot. 3/4 inch. Factory set to 50. About $60. Then male and female brass hose fittings so it can be connected to hose connections. I connect it to water supply and then hose to coach to it.

Works great.

My pressure was good at first then would get low. Used the pump to compensate but would drain the tank and suck air. Ended up being the hose had a kink in it deep in the reel and restricted flow.
