I've determined I have a leak where some water is coming out the waste pipe when in filter mode, and from reading the spider gasket seems most likely. Amazon has a "rebuild" kit for my valve which I'm planning on ordering but I had a question on putting the new seal in.
I've read some indicate that you're supposed to use an adhesive on the bottom of the seal, but apparently some don't advise that.. How do you know?
Also, as I'm in the middle of a SLAM shutting everything down for 24 hours waiting for the glue to dry would probably mess me up.... Question is, can I just lube it up with the silicon o-ring lube and put it in with no adhesive and see if it's OK (at least no worse than current hopefully), and then add adhesive later if needed?
Alternative is I just deal with the leak until SLAM complete and keep adding water (which also probably makes SLAM less efficient since added water is 2ppm FC).
I'm also working on getting a ball valve on the waste line as a backup but wasn't successful yet. I got a valve that I thought didn't need the cement, but apparently I was wrong..
