Hello. I have a Hayward S244t sand filter and I have determined that I have a bad spider gasket. I removed the bad gasket (and yes, it's in bad shape and needs to be replaced), and when I Googled for a replacement gasket the first couple of sites I ran across said that I had to replace the entire diffuser because the gasket comes glued to the diffuser (as though I couldn't glue a new gasket to the existing diffuser?!). Surely there is somewhere I can order just the spider gasket and glue it in myself? THANKS
