good day all ...

I have used the small bullet style regulator but knew it was preset to 30#'S. So I got an adjustable one with a gauge. reading I can use water pressure up to 45#'s on my coach (this was a doc left by the previous owner).

So my question is: when I have the coach hooked up to city water supply and we are running water in the coach -Shower- the gauge reads 46#'s BUT when we close/ turn off all water in coach the gauge reads 80#'s. Am i using it correct? I would think 80# would burst the small pluming pipes. How does the regulator work?

Thanks,
Dazes and confused/overthinking it!
