Started noticing air in the pump basket a week ago, and then a day or two later, coming out into the pool. And finally, it stopped priming on its own in the morning.
I have two skimmer suction lines and if I turned the shallow off it went away. If I turned the deep end off, they stayed. So, process of elimination, it's the shallow end. I looked everywhere visible and couldn't find the problem until I, by chance, heard air coming out of the ball valve handle. I pulled the handle off and if I move my finger around, I can tell there is air coming out (change in pitch of the noise, if that makes sense). I ran a hose over it and sure enough, when I run water over the handle stub, the air bubbles go away immediately.
So... what's the easiest way to repair a leak in the handle? It's inside there, if that makes any sense - anything I can just squirt or spay in there? I'm trying not to replace that part of the plumbing - it looks like decades worth of some plumbing cement holding it together that I would rather not fight with
