OK, I posted another topic looking for the adhesive to use with the new sproket gasket I got for my Hayward sand filter. But apparently it isn't the sealant that's causing the leak?
From the top, end of last year water started dripinging out of the backwash on our filter, I was told I needed a new $100 valve. Then when I started looking into it this year I was told just to rebuild it, or replace the sproket gasket. I replaced the gasket, dry, it still leaks. There aren't a lot of parts in there, so if it's not the sproket gasket, then what's causing it to leak??
