I have a Pentair WF-28 WhisperFlo Pump that is about 3 1/2 years old. My "spa-pool" is an in-ground spa of approximately 1200 gallons. Lately the pump, housed in a pool shed about 50 feet from the "spa-ool", seems to be much louder than previous, and even the waterfall doesn't drown out the noise. Obviously I will need to consider replacing it, but I have two questions.
The first is whether anyone knows about how long I might have before it dies? I know that none of us has a crystal ball, but as this is my first pool pump, I'm just wondering whether it will operate for another few months, years, or whatever, once it starts making the louder noise? Husband thinks it's the bearings. Will the pump give me some sort of indication/warning that it's about to quit, or will it just stop altogether out of the blue?
My second question is whether I can just replace the motor part of the pump? Husband thinks this should be possible. Does anyone know? And if I can just replace the motor, do I get a pool service to do this repair, or an electrician?
Photos of "labels" on Pentair pump, and pump area attached in case they are of help in answering my questions above.
Thanks so much as always!
