Question What's your RV water pressure when pump is off?

Neal, the static pressure in all lines in the coach will be whatever is set on the regulator. Depending on the demand, it will vary lower than the preset pressure. More demand will decrease the pressure depending on how restrictive are the filters, check valve, number of 90 degree fittings etc. while the supply line is trying to make up for the pressure lost.
But overall I think regulator set to 55psi is "middle of the road " safe pressure for the supply line.

Neal, I've not checked line pressure in the coach. But, as a comparison to the S&B, there seems to be plenty of pressure to the sinks, and great water pressure in the shower! And that's my main concern!
I wonder, does it being "new" (6 months) make any difference?
