I've just had a new motor installed on my Superpump, a 1hp. This is the 5th motor in 6 years. With this one, I decided I would have it installed rather than doing it myself, trying to rule out ME as the failure point. The problems we've had with them have pretty much always been that they get extremely loud, bad seal.
After installation, I asked the installer what I've been doing wrong, and how long these things can typically be counted on to last. He told me they can last 10 years without an issue and the main thing that contributes to success or failure is how well you take care of it.
I asked him for some details. He told me when we close the pool, to remove the lid and basket, shut the valves coming from the pool, have someone stand at the switch while the other person stands at the pump. Then turn on the pump and once the water is out, spray WD-40 into the impeller, then shut it off. Also spray a whole bunch of WD-40 into all the vent openings on the motor body. Then wrap the whole thing in a garbage bag and keep it tight with some duct tape.
Any of this sound like a good idea? Anyone ever heard of this before? My parents and another couple on our street have both had their current motors for 8 and 11 years with no issues and they do none of this.
I really appreciate any input anyone can give!
