Anyone have any Information that may help? Ideas would be greatly appreciated or a thread that gives me more definite allowable pressure.
The first thing I'd do is either connect the potable water hose directly to the city water bib without the pressure regulator installed and see what kind of pressure you get at the shower. Alternatively, if it's convenient, you could run your water pump (with water in the tank, of course) to see how your shower works on "internal" water pressure.
It may well be your lack of pressure at the shower is caused by manufacturing debris in the line forming a partial clog.
Once you establish that the shower works to your liking, then install a pressure regulator set for no more than 60 psi, since you were happy with that pressure before.
