I have been trying to get this figured out. I have a 15x30 soft sided pool 13,500 gallons, new 1/2 hp whisper flo (110), waterway fc100 cartridge filter. This was here before I got the house with the exception of the new pump. I over heats in about 1 hour or so and is over amping at 12 amps. The suction line is 1 1/2" along with the 1 return line also at 1 1/2" (eyeball 3/4"). The skimmer is 10' from the pump with 3 90 degree elbows. The return is 17' with 4 90 degree elbows. My filter pressure is at 16 it was at 6-7 before the new pump. I dont want to spend anymore money on this if I dont have to. Should I create more head instead by adding more 90 degree elbows? Would getting a bigger filter solve my problem or a variable frequency drive? I have checked all my wiring and connections. If a filter is needed recommendations are appreciated.
