The original gasket lasted 6 years. Then the next two, lasted 1 year each. I must be doing something wrong. I did spend a long time cleaning up the old sealant so that was not the issue. The first time I used permatex ultra black. It dries very hard and was just as hard to remove as the OEM stuff. The second time I use permatex gray (suitable for cooling systems - so I figured it was ok for the wet service). Another fail!. Now I read where people use permatex blue 80022. Is that the thing to use? Pentair recommends Loctite 401, 403, or 416 but the pricing for those is INSANE! $15+ for 0.7 oz! What do ya'll use? I've read where some use no adhesive, or grease, but I don't see how it would stay in place w/o glue.
Another issue. I bought the replacement gaskets from Liberty Pools (Amazon). They were supposedly Pentair parts (pn 271148) but were not in Pentair labelled packaging. The OD of the gasket is a tiny bit too small. I have to very carefully work it into the outer ring groove in the valve body, and then it tries to "pop out" of place. Is this normal, or did I get a knock off crappy part?
I have done a lot of googling and the adhesive question / problems seem to be common. Any help would be appreciated.
