I can't get more than about 10 psi water pressure when running across the lake. Have replaced the prv and impeller. Checked t-stats and they appear to be opening and closing properly. Tried a different gauge. Blew air through the motor and it seems fine. The motor does not overheat. And the heat sensor works. Does anyone know what could be causing this? It runs fine but it has me concerned. Any suggestions on where to look now would be appreciated.
Thanks
