I have a sta-rite 1.5 HP pump and the motor was replaced last year with a generic 1.5 motor. Last year the pump also had to be rebuilt because it had run hot and melted some of the parts at the impeller. The motor is still working but runs VERY hot and occasionally will shut off. I am debating on replacing the whole pump versus the motor as the guys who replaced the impeller didn't replace all of the damaged parts. Or should I just replace the motor?
Next set of questions is should I go with a 2 speed or variable speed? And what HP? I know the guy that built the pool did no calculations to find out the best HP. He actually replaced the pump three tmes in the first couple of months. He started with a 3/4 HP on the pool and a 1HP on the water feature seperate, then went to a 1 HP on each, then replaced both with a 1.5 HP to run both from one pump.
