So if my pump is off for a period of time and I turn it back on, I can see and hear air being cleared by the jets. I'm assuming there is a slow air leak somewhere, but I don't see any obvious leaks from the plumbing anywhere. I do hear a sucking/sipping noise from the multiport valve and looking at the pump lid (hayward superpump) i can see a little bit of air swirling, which I've read is not optimal. Can that mutliport seal go bad and cause a leak?
Air bubbles during startup after pump is off after awhile?

The multisport can leak and they have rebuild parts for them. When pump primes it should clear the lid to solid water. Any air under lid is from suction side and wouldnt be caused by a leak after the pump. Most systems make noise and bubble a little on startup from the initial churn of water
Thanks. I don't see any leaks on the suction side but I used to have a tiny leak on the pressure side right at the pump housing. It's since disappeared when I cleaned the filter. Is it normal for these pumps to have to prime every time they start?

No, the pump should not have to prime every time it starts. If the pump is losing prime when it is off, there is an air leak somewhere. It could be on the pressure or suction side of the pump. Keep in mind that an air leak may not show up as a water leak when the pump is running so they can be very difficult to find. When the pump is running and after it primes, is there any air in the pump basket?
You can see small swirls against the lid. Does that indicate air? I thought it was normal to have a little.

Yes, that is air. But when you are running the pump are you seeing any air coming out of the returns (non SWG related).
How about when pump is off. Are you getting low water under lid or a large air bubble
I've never thought to look for that. will report back in the AM. In other news, my small dribble leak at the pump discharge port is back
I'll have to check, I seem to remember seeing a fine mist of bubbles when looking at the jets underwater, but that was last year.

That is probably the swg. It makes hydrogen bubble while running and the are very small with high flow rates.
Sounds like the return side leak could be the source.
