Response to Have a 18000 gallon pool, 3/4hp whisperflow 1 speed, average run is 42 feet and filter is a Pentair Clean and Clear 320 (3 filters inside, says will handle 50gpm) plumbing 1 1/2 inch piping. 8 year old system, the pool now pump shuts down when hot. I have a Rheem 6310 heat pump and it starts and shuts down with low flow code. System seems to be pumping at about 12gpm. I am wondering since I have to replace the pump if I should go with a bigger flow pump. Thanks for any help.
