I started to take my Hayward superpump apart yesterday to see if I could repair it or if I needed replace the entire thing. The motor seems to be fronzen. Before that it was screaming for a long time, so my guess is that the bearings have seized up.
The pump and motor are over 20 years old. The pool is using a Hayward salt system, but the pump is unchanged from the previous system.
The motor is an A.O. Smith ST 1102. The pump is a Hawyard SP2610x15.
So--I decided to take the pump off and see what I could see. I loosened the four bolts and water started pouring out. A lot of water. I did not take the pump off. I left it in place, but the bolts were loosened with a good bit of play left and I pulled the motor maybe one quarter - one half inch back from the pump.
The water gushed out. 10 minutes later, the water was still gushing out. And the water pressure had not diminished. It looked like it was emptying the whole pool, although I can't imagine how that could be.
Is it just emptying the water from the sand filter? What is going on? I am afraid to take the pump off completely with all the water coming out. As I said, in the course of 7-10 minutes, the pressure did not diminish.
I would appreciate any insights you might have.
