I have been getting some air in the spa side jets, but nothing in the pump basket or pool. Do you think that to be a leak on the return to the spa only, and not on the suction side? If there was I would also have air in the pump basket. Correct? Thanks

Pressure side leaks almost invariably leak water, they do not let air in.

Spa jets almost always have air feeds as part of the jet. Are you sure the jets weren't designed to draw air in from somewhere and mix it with the jet?

I know the blower works, if I had a suction side leak, there would also be air in the pump basket? Correct. Well the returns go one to spa then spill over, but the pool jets have no air. I think your right...

There doesn't have to be air in the pump basket for a suction side air leak, though there almost always is. An air leak in the impeller housing would not visibly show any air in the strainer basket, but then pumps hardly ever leak there.

The does have to be air in the filter if you have a suction side air leak.

The spa jets can still draw a little air even if the blower is off. Some kinds of jets draw a lot of air with the blower off, but all jets that work with a blower can still draw at least a little air even with the blower off.
