I have a Pentair Whisperflo pump. There is water leaking from behind the seal plate of the pump, under the motor. Exactly like you would expect from a bad shaft seal.
I replaced the shaft seal. Still leaking.
I replaced it again, thinking I might have accidentally touched it or got some dirt on it. Still leaking.
I called a pool repair guy. He also replaced the shaft seal. Still leaking. He then suggested rebuilding the MOTOR, which didn't make sense to me - if the problem is that water shouldn't be getting to the motor in the first place. How could rebuilding the motor fix that?
By this point, the leak had increased from an occasional drop to more of a steady flow.
I replaced the seal plate, thinking maybe there was a small crack. Still leaking.
I replaced the impeller, again thinking maybe there was a crack. Still leaking.
As far as I can tell, I've now replaced every part involved in the wet/dry separation.
I'm quite certain the water is not coming from somewhere else and running down under the motor. I can post a picture of the leak if that would be helpful.
What else can I do? Is it possible the repair guy was onto something with rebuilding the motor?
For now I'm just letting it run and leak. I know it will eventually ruin the motor, but at this point I've probably spent more on failed repair attempts than a new motor would have cost anyway.
