I am hopeful I have miss calculated the dynamic head of my pump system. I recently moved a solar heater from ground level up to the roof. I have an Intex pool with a 1500 gph pump/filter combo ( 25 gpm). We think it calculates to a 1/3 hp pump (110v x 2.1A x 0.001somthing). I have approximately 80' of 1.5" PVC pipe up to the heater and 80' return. There is a 20' rise from lowest point in the system to the highest. I calculated a head loss of 3.8/100 foot of pipe. 7.5/90 elbow of which I have 25 (yes way more than I should have but I moved the system and there was no real direct line to take). 1/foot of rise and 9.3 for the heater this is just a guess taken from a calculator site. This gives me a TDH of 223 which is off the scale of any of the pump flow charts I have looked at. Any help suggestions would be greatly appreciated.
