Is my pump motor going bad? I dont notice any loss of performance and still pumps the water fine, but I've been noticing a loud wobbling sound from my motor. It's like a... "wa...wa...wa..wa..wa...wa.." The shaft spins fine. I disconnected the motor from the front part and ran it to see if it still makes the noise. It does make a noise, but it's not the exact same noise. It's a pulsating but a lot slower and longer. When I reassembled it, and turned it back on as it was priming the wobbling noise got quicker and quicker and louder as the water filled in the basket. Although it had no trouble priming and running. Other than the noise, you would think nothing is wrong with it. There is no air in the system. No loss of pressure.
It almost sounds as if maybe the shaft somehow isn't aligned right or something. The impeller is all clear and that looks OK.
This is a Pentair Whisperflo. Motor isn't very old.
