Polaris 360 air bubbles

Welcome to TFP.

You probably have a minor suction side air leak.

Post pics of your equipment pad.

 
Here’s the set up. Pump motor installed in the last week.
You may have a bad glue joint with the pump install.

Wrap Saran Wrap around the suction pipe from the pump to the ground and see if the bubbles go away.
