I get air in the pump on low speed. The pump cover is very easy to remove compared to last year. I just checked the pool store for a new pump cover gasket for it. They tried to tell me the lid is sold as one unit $81.00. No thankyou. Checked on line and the cover with attached T-gasket is sold as one piece, minus the locking ring $22.00. I'll have to take a closer look and see if I can find an o-ring that would work. When the pump switchs from high to low speed the lid moves quite allot. Can't see spending that much money every couple of years.
