This issue has been driving me nuts for some time now.
When I turn the my pump off I hear a loud whooshing sound and water backs up through the plumbing and comes out of the skimmer, sometimes with so much force it blows the lid off. It also will push the weir flap up into a stuck position so the next time the pump turns on it has an extra hard time priming.
I've read a lot about it being a suction air leak. I added pool water and it persisted. I changed the pump drain plug and gasket, the housing gasket, the diffuser gasket, the jandy valve gasket just before the pump, and the pump basket lid gasket. I've tried soap suds to see if I have an air leak in one of the glued fittings but no suds get sucked in anywhere.
When I open the sand filter air release, initially lots of air is pushed out and then water comes out but air still is coming out with the water in small spurts. It is never a nice steady stream of water coming out of the release.
The ONLY thing I've done that has temporarily fixed it, is to backwash the pool. I backwashed 2 nights ago and the sweet sound of silence followed when I ran the pump and shut it off. The next day however I had the problem back again. I have added DE to my filter in the past. Is this possible a part of the problem?
Tonight, after adding more water than I like to see if that would help, I backwashed for about 2 minutes to bring the water level down a little and the problem went away. When I open the air release on the sand filter it's a nice steady stream, and when I turned the pump off, it's silent and maintains prime. This was about 10 minutes ago.
I'm letting the pump run tonight and then I'll check it again in the morning after it's had some time to be off, but this is driving me crazy! Any ideas, tips, tricks are more than welcome. Thanks in advance!
