We have a 5-year-old pool pump that started making a buzzing sound that goes up and down. I've listened to different pool pump sounds on youtube and on your forum but haven't found any that sounds like mine. The pool company said that it's the motor and they want to replace it for about $450. I asked whether they can just replace the part of the motor that's broken but they said that they don't really disassemble pumps that small (Hayward self-priming Super Pump model C48K2N143B1).
I put a short video of the sound on youtube:
I would appreciate any advise.
thanks so much!
