We run 50-55 Pounds on ours as that is needed for the tankless water heater. We regulate it through a Watt water regulator.

We opened up our camper this weekend and hooked up the water with an inline regulator. After flushing the water system, I started working on something eles and the outside shower faucet handle blow off the faucet. Luckly I had the door open from flushing and no water entered the unit. I figure the regulator went bad,and I have no idea what my supply pressure was. Not many people were at camp and I'd say the pressure was pretty high. In hindsight the pressure when flushing was higher than normal. I'm replacing the regulator with one that has a gauge.

I use an adjustable Watts-285 regulator, and keep it set at 52psi. Gives me great pressure with super flow !!

I changed my internal regulator from 45 psig to 60 psig and it works much better.

My RV says "45PSI max" but I think Im feeding it 49 (As close to 50 as I can get with the gauge I am using) Generally, from what I am told, PEX can take whatever you feed it (Within reason, 120 NOT a problem) but sometimes the fittings get a bit....anemic.

But some of the valves used in RV's start blowing up around 60 PSI. so 45-50 is what I consider the safe range.
Home was where I park it. but alas the.

We use a household water pressure regulator screwed onto the faucet and factory set at 50PSI. No problems. And its big enough so we don't forget it when we disconnect to leave the campground.

I have had my Watts whole house regulator set to 65 psi for ten years. I have spent three summers where the unregulated pressure was 140 psi so my plumbing and fixtures have seen extended periods of time at 65 psi.
Early on I replaced the kitchen and bathroom faucets with residential units that are rated to 85 psi. The shower is still the original RV type and still works fine.

We usually use our fresh water tank and own water pump when setup. The city water connections always are different everywhere we end up.. I know what the pressure is using my own water pump... Since we camp alot off the power grid always nice to know if the fresh water tank and pump is working good anyway.

I hookup a water hose with spigot to the city water connection and hang the spigot on the front deck railing. Great for squirting squirrels.. Easy to fill up fresh water tank with spigot.

I use an adjustable Watts Regulator on city water supply.

It is set at 50# static
Is it time for your medication or mine?

The highest pressure is dependent upon many factors including type, manufacturer, age, type of construction, etc. When I purchased my current coach, I contacted Monaco with this question. I was told that, at that time, Monaco was testing each coach during the final assembly, and each coach must pass a pressure test of 100 psi. On the other hand, Monaco also advised me to keep my water pressure at 50 psi or lower because the "weak link" in the system would be the incoming water hose.

I too sometimes turn on the pump when taking a shower or using the kitchen faucet sprayer. The parks utilities are my first choice over our own resources but, water pressure can vary. Like to use the electric heating equipment when available.
