Re: Noisy Hayward super pump, Lube?
It really depends on the type of noise. If it sounds like grinding, it's most likely the bearings (again), or the motor about to fail.
If it sounds like popping, it may be cavitation.
What is your filter pressure?
hmm, just noticed that you mentioned that it makes this sound when it first starts up...about how long before it quites down?
I have this symptom with my sprinkler pump, which draws the water from the backyard lake. It does this because it looses prime when the pump shuts down. So it's spinning the impeller and makes this noise until it catches prime.
There's really nothing that you can oil or lube on a motor.
