So my goal it to to run my pump at the most efficient setting while keeping the pool heated and chemically balanced. I recently replaced/upgraded my pool heater. As the directions recommended, installed it with a bypass valve (3 Port Diverter Valve). I noticed that when I bypass the heater, my IC40 cell will register flow with my pump set as low as 750 rpm. However, when my heater is active (not bypassed), I have to run my pump at 1550 rpm for the IC40 cell to register flow. Is this normal operation or is there a blockage in the heater???
