Air Bubbles in the Return Jets. My Fault?

[ccostan]

Thank you everyone for the great replies. I did just replace the Pumps lid rubber seal but did not put any lube on it so I will try that. Unfortunately, there is not much above ground piping between the pump and the skimmers. (Although since I see air even when I switch from skimmers to Main Drain - It is probably somewhere from that y switch to the pump right?) That section is all expose and I will try the towel trick to see if I can make the bubbles disappear from the lid of the pump. I'll keep everyone posted.

Thanks again for the suggestions.

CARLO.

Funny that this post should appear when it did. I just spent this morning solving this very problem.

Lubed the gasket on the pump where you access the basket. - bubbles
Checked the tightness of all the fitting on the plumping coming into the pump - bubbles
Replaced the Teflon tape on the fittings to and from the pump - no bubbles

I think the real cause was the intake fitting wasn't tight. I think over time the installing and removing of the pump each winter loosened it.
