I read a bunch of threads on this, and I'm pretty sure it might be my SWG, but I figure I'll ask anyway...
I notice, from time to time, not always, small bubbles coming out of the closest return line/jet, the one next to my polaris port. The other 3 are fine, no bubbles at all. I have no bubbles in the filter basket at all (solid water) either. When I open the filter basket and reseal, it takes about 15 minutes to clear out the air. Also, I show no signs of leaks above ground, and my water level only seems to drop a bit due to splash out and evaporation. I read that SWGs can introduce bubbles. Is it as easy as, shut the SWG off and see if they go away? Is it an instant affect on the bubbles?
I will say now, although I want to double check, that I can hear something, maybe a slight hiss, when I'm seeing the bubbles. But I would think that makes sense and isn't an indicator of another issue or real leak. At least I hope not. Pool is pretty much new and patio was literally just finished yesterday!
I'll also double check my strainer basket O ring and filter drain plugs tonight.
