Thanks Cary.

It is this pump:

Model #1450-0011

If I read the performance chart right it should be capable of 40 psi and ~9GPM at 65ft. Static water level is ~20ft.

I don't know how this translates with the CSV1A between the pump and the tank tee running @50PSI.

I'm using 160psi poly so I don't think I am stressing it.

Other than installing a pressure gauge

Question:

How do I determine the maximum pressure in the line before the CSV (i.e. between the pump and CSV) in a system with a 1/2HP 12GPM pump set at 65ft depth with the CSV set to 50PSI with shower running?
