park water pressure
we just returned from a family reunion and when we checked in they told us to be sure to use a pressure regulator since the park had 110 lbs of pressure at the faucets. that's right 110 lbs and belie...

Highest we've seen is 120 psi so far. Have heard reports of up to 200 psi. If you're going to install a regulator inside or at the city water inlet, you should be using a high pressure rated hose. 110 psi is unlikely to hurt anything inside but a cheapo hose with no rating won't withstand high pressure. We have a regulator inside and use a Valterra high pressure rated hose. I also installed a solenoid valve and can simply switch the water off at the door when going out.
Our reinforced Valterra hose has a rated working pressure of 160 psi and burst pressure rating of 340 psi.
RVs are supposed to be tested to 100 - 110 psi. The PEX piping, faucets, etc. should be fine. The PEX itself is def. fine. There is a standard somewhere that requires the testing or it might be RVIA that requires it and have seen it in the past.
I'm more worried about the toilet overflowing than pipes or hoses bursting. Our lovely Thetford toilet has nearly overflowed twice now. Once due to low CG pressure (around 10 psi) and once because the flapper valve was sticking. A flooded RV from an overflowing toilet can cause serious damage and even result in a write-off. Shutting the water off when leaving your RV is good practice.
At least a cheapo hose acts like a fail safe device and won't let extreme high pressure inside! :)
