Should it be necessary to replace the Strainer Cover gasket on my Hayward Superpump on an annual basis?
Each year a new gasket seems to last for a couple of months and then when I take the cover off to clean the strainer, the gasket jumps out of the groove. Then I have difficulty getting it reseated in the groove and the lid closed as the gasket seems to have increased in length.
I am using Aladdin teflon based lubricant/sealant called "Magic Lube" on the gasket. This is the stuff that my local pool folks use. Could this be causing the gasket to swell? Am I tightening the strainer cover retainer knobs too tight? These are the only two things that I could think of that might cause the length of the gasket to increase.
