I am having to replace the spider gasket on my Hayward multiport valve as it's not turning easily, and that was one of the signs last time. Watched a bunch of videos for a refresher, and while some say to just put adhesive at the T intersections, others say to run a thin bead along the spikes and outer circle. Any opinion on which is better? When I replaced the last one a year or two ago, I did the T intersections, but now I'm having to do another replacement, so wondering if it should be glued better? Thanks.
