My filter pump has been making a high-pitched screech and I feel like it's time to replace it. It is the original pump from when we installed the pool 13 years ago. The system is a Sta-Rite Max-E-Pro single phase 1 HP (SF 1.65) and our pool is about 20,000 gallons. We also live in California where our average summer temps are high 90s to 100s.
I've read your article on 7 Biggest Mistakes When Replacing a Motor and I have a few questions:
1) Is it possible to replace it with a dual speed (or even varialbe speed) motor? Will I need to change the wiring to the motor or at the control panel? I would really like to take advantage of the engergy savings of a dual speed motor. We also have a salt system but have since shut it off due to the fact that we had to run the pool so much to keep the clorine generating, which in turn ran up our electric bill.
2) Would it be recommended that I replace "everything?" I know I should replace the shaft seal, but what about the difusser, motor housing, or other parts? There is some corrosion around the housing and it looks like some of the bolts are rusted and I would hate for them to break off when trying to remove the motor. (This happened when I had to replace the pool sweeper motor.)
Any help and advice would be greatly appreciated.
