DM,
Maybe this should be a separate thread but since that's a borderline call and this thread isn't long I guess it's OK to leave it here.
I'll probably open another can of worms like the great DE Filter debates, but I don't like the crazy glue idea. Tried it and worked for a bit. There are others on this forum that say don't glue it at all but I can't see how it would stay in place except under a very limited set of conditions, like absolutely no water flow when changing positions.
Lost my records but I think it was early last year when I reglued mine. Cleaned out the channels with a small flat screwdriver and sandpaper, then used silicone seal to hold it in place. Had to make something to prevent squished silicone seal from sticking to the top part of the valve that bears on the gasket. Cut a circular piece of plastic sheeting with a hole in the middle for the center part of the gasket so the sheeting lays flat on the gasket. Coated one side of the sheeting with wax as a mold release. Silicone doesn't stick to wax. Filled the channels with silicone seal, set the gasket in place, put on the sheet, then reassembled the valve. The top part under spring force squished the gasket in place. After curing for a day, took off the top part, removed the plastic sheet, then using a blade, cut any excess silicone seal that squished out.
Just took it apart the other day to peek and seems to be holding in place very well.
Time will tell.
