28,000 Gallon In Ground Vinyl Liner
Suction Side: 2 Skimmers 1 Main Drain

Equipment:
Hayward Super Pump 2
Pentair Cartridge 520 Filter
Hayward CL200
Hayward Heat Pump - W3HP21404T
Last year prior to closing my PSI gauge would read 20 PSI when the filter was clean. I recently finished installing the heater listed above. I installed a bypass using diverter valves. When I have the heater bypassed, as in not in the water circuit, my PSI drops to 11-ish PSI. When I bring the heater into the circuit, meaning the pipe between the valves is cut off from water flow and all water is directed into the heater, the PSI jumps to 20 PSI. See attached pictures with water flow direction. Keep in mind the photos are prior to completion, but it was too dark tonight to take anything. There is more pipe in the mix now that I installed a heater. So my question is... where should my pool pressure be? Was 20 always too high? Is 10 better? Is a 10 PSI swing acceptable?
