Thanks for your reply..
It shows air on return while running...I meant pump basket ( sorry)
No Matter how long it runs the air never goes away. I don't have solar (not sure what that means)
There is a clear tube that runs from the top of the pump into the multi port valve and I see the air moving through that clear tube, but no air shows up in the basket. All the returns will show air also, not just the stair return or the front returns.
Thanks again
