Air bubbles in return jets

[TGMcCallie]

My pool has a lot of small air bubbled that come from the return jets.

What is the most likely cause of this problem?

Thank

A suction side air leak. There is an article in Pool School that may help you.

Thanks, I have a pool man coming Monday but I just wanted to kinda know what kind of a problem I may be looking at.

Round up the usual suspects: low water level, stuck weir in the skimmer, loose drain plugs on the pump, poor seal on the pump strainer basket, and leaks at the fittings, especially any couplings.

In your particular case, I'd also add a good eyeballing of the inline chlorinator. You might be getting some venturi action in there and drawing air through the lid.

If you coat any suspicious areas with shaving cream one at a time and watch the bubbles, you might get lucky and locate the leak.

Problem solved: I use a Hayward 4 port valve SP0735 to switch the flow between main and skimmer. This valve has a little shaft 0 ring. This O ring was bad
and there was where the air was entering my system.

I had a new one that I had ordered years ago as a replacement in case they ever quit making it so I would not have to replumb my system, so I just changed it out with the new one and now there are no air bubbles in my system.

This is for information only in case other people have a similar problem.
