High pressure water supply

We are staying a RV park in San Antonio and the water pressure at the park at each site is 110 PSI +. They do warn you as you check in to be sure to use a hose end pressure regulator at the water valve to protect your water lines and hose. So I pulled out my trusty brass hose end water regulator and screwed it onto the water valve and then hooked everything up. My water regulator has a small gauge and it indicated that I was at the preset 50 psi and everything worked fine until around 10:30 pm when I heard a noise around the bath area like running water. I went out side with a flash light and found water running out at the bottom of the hot water heater door and when I looked at the gauge on the regulator it showed over 100 psi. I turned off the water and opened the water heater door and found that the pressure regulator on the water heater had tripped. It is set at 100 psi. I bought a new hose end regulator this morning and I am back to 50 psi. I was surprised that my old regulator failed but I guess nothing last forever. Or maybe these things will fail if the pressure gets to high, 110 psi plus. I have never stayed in a part with water pressure this high. I just hope the new one holds up for a few days. I plan on turning off the water at the valve when we are gone and at night.

High water pressure....and low Electrical voltage!
These are two things that need to be watched closely.

I learned about putting the pressure regulator at the campground faucet when the owner told me the pressure was 120 psi and to put it at that end or I might blow out my hose. The newer Airstreams have a built in regulator, but I don't trust it and always use one at the faucet. If a regulator fails, the mess isn't worth it. Don, I hope you didn't blow out anything in the trailer. The campgrounds cannot be trusted to warn you.

My last trip out I was parked for a week with high pressure. Did not blow but had a real slow leak below my closet. It was raining so I did not find out until I was ready to leave. Floor is just drying out and did some damage to OSB. I thought I had a regulator on my city connection. Wrong!
I'll have one next trip
