replacing pool pump

 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.

regards,

David Troutman

Hello David - If the equipment is below the water level of the pool, it will continue to drain. You'd have to either close the valves so water can't flow or put plugs in the skimmer, jets and other sources of water.

If the equipment is above the water level, it should only drain the filter, pump, and pipes above ground.

Hi there, and thanks for your reply.

Here is what happened--

The pump was below the pool water level.

the shutoff valve did not work.  It slowed the flow down, but did not stop it.

I let it run for about 36 hours, and finally it stopped.  I will now replace everything, fill the pool up again (I think it was about 2-3 feet below the pool level, and it is a big pool, so it took a while to get the level down).

I have posted another question on the site today about the process.

Thanks again,

David
