Pump Runs But Nothing Happening

Postby Guest » Tue 01 May, 2007 10:44

I have a 30k gal pool, the motor seems to be running as smooth as always, yet nothing is happening, no water is getting pulled through the system. Any clue what the problem is?

Thanks for any help

Turn the pump off and remove the pump lid, then fill the volute + suction lines. Once full, replace lid and turn on pump. If it then looses the prime again, you may have an air leak.

...................air leak, or a clogged impeller.

Hello again,
I filled the "volute" although it stays up fine and really didn't need more water, you can even see the water line touch the lid. Nadda. I even let a water hose sit in the volute while the pump was running for 20 min or so, that didn't help either.

"Suction lines" - I held a water hose in the skimmer inlet, where the pool hose connects, and made sure that that it was tight. Lots of air was released into the spa. I did this until it stopped, then turned the pump back on. Still nothing. Any other lines that I can check? I really don't think I have a leak, but how would I trouble-shoot that anyway?

It's really awkward to take the motor off to check the impeller, how could I check it w/o doing so? Also, can just the impeller be replaced if it comes down to that being broken?

Here's an image to my pumps setup if it helps:

Thanks for the help

When it comes to an air leak, it really doesn't happen over night. You would notice it before hand, but I'm not ruling that out because your equip looks to be quite old.

It's better to remove the motor form the pump to check this and if it's broken (yes, you can buy a new one) you will need to remove it to fix it.

Thanks Chris,
I'll remove it and have me a peek-see.

If basket is full of water and it is still not pumping it has to be a broken impeller. I had the same thing happen last year, parts were easy to come by. However it looks like it is going to be difficult to get you pump apart.
