City Water Pressure
Hello, I have a 2019 Georgetown GT5 31L5. I place an adjustable water pressure limiter at the city source when I hook up. I have it set at +/- 45 psi. I have noticed many rigs (all different manufacturers) set at various rates including much higher than 45 psi. Does anyone know the recommended psi for this model?
Thanks

45 psi is a great number , increasing it bit wont do much for the coach.
45 is probably what the onboard water pump does too.
When purchasing a regulator it must have a dial and MUST be rebuildable as many cities have hard water that will build up deposits in the unit.

45 to 50 pounds of pressure is safe. Is there a "recommended" pressure? No, there isn't. Limiting water pressure protects your coach from leaks, blown lines, etc. I've seen people who never use pressure regulators, and seemingly never have a problem, but IMHO they are living on borrowed time.
If you are getting good water pressure for showers and to flush your toilet, stick with your pressure set as it is.

45 psi is sort of the normal myself I run 40 pis using an adjustable pressure regulator. Look on your potable water pump data plate for the high cut out pressure your rig is designed to handle that pressure

Our owners manual actually says to keep ours below 60lbs. It is tested much higher to ensure no leaks. Read it and it should say what to use.
I set our pressure to 55psi. However, many times the city water is less, anyway. Our water pump puts out about 50psi.
We also have a secondary one-way valve, behind out water pump, since we've had pump-mounted one-ways fail in the past, and it fills up the fresh water tank to overflowing.

It's hard to put an exact "highest" PSI on any rig.
While the PEX tubing can handle much, much more than that, the often used plastic fittings and shoddy installation usually cannot handle the high pressure that PEX can.
I shoot for 50 lbs.
That is what my pump puts out and we are comfortable with that pressure.
As mentioned, many (and I almost want to say most) campgrounds do not have even 50 lbs.
A few were slightly higher and two at 80 lbs but that's it in 40+ years of camping.

Just to let you know each situation will be different. If I set the regulator to more than 38 psi the toilet has 2 holes at the front of the bowl that shoot upwards toward the seat and the floor gets wet. We have a Dometic 310 which doesn't have a bowl rim.

The SHURFLO water pump you probably have installed turns itself off at 55 lbs psi and turns itself back on at 40 lbs psi.

My adjustable one is set on 50 lbs. My last campground ran about 40... couldn't get to regulator's limit.

Just like with lots of other things, "just enough to get the job done" is the right pressure setting.
If I can get a nice shower with 45 psi water pressure, why risk more?
