Started a couple of days ago. Everytime we turn off the pump you can hear
this big "whooshing" (for lack of a better term) noise and all of the water
goes out of the pump basket. It's like we have to prime the pump when first
starting up the pool. Takes a long time and then the pump basket will stay
full and everything operates fine....until evening when we turn the pump off
again and then "whoosh" the water is gone again.
Any ideas or what other info I need to give for you guys to help?
