I'm having a few issues, not sure if they are related, or even if they are really issues at all. Sorry for the complete lack of proper terminology here...
1. I've noticed that, since opening this season, it seems to take the pump about twice as long as when closed last season to totally fill the pump strainer basket area (so that there are no air bubbles). Sometimes it will sit for more than a minute without all the air getting pushed out, so I stop the pump, open again, make sure there is no crud in between the cover and the rubber gasket, then close and restart, and it will work, although again it is much slower than last season. The gasket itself looks to be in good condition, although I have noticed that in a few spots the adhesive between gasket and pump seems to be failing. Doesn't seem like this could be an issue, though, when the lid is on and screwed down tight. I did spread some of the silicone lubricant when opening. Also noticed that my returns seem to be weaker than they were last season. Have seen no indications of any actual leaks in the plumbing. Is all of this caused by a gasket that actually is failing, and if so, do I need some new adhesive for it, or something else? Or, is this indicative of a looming pump failure? I'm not sure how old the pump is, since I just moved into this house last season.
2. Also new this season is a gurgling sound from the sand filter -- in particular, it sounds like it is coming from just under the multiport valve. It goes away after a while. I don't remember any kinds of noises like this coming from the filter last year. Filter performance seems fine.
If any of this rings a bell with anyone, I'd appreciate your thoughts. Thank you.
