We have a raised spa that is plumbed with an air blower. U can see how it is plumbed in the attached. Even with the air blower off I still get som bubbles from the dirt return coming from the equipment. Wondering where the bubbles r coming from. Could the flow of water coming from the equipment and out the returns create suction that brings in some air from the blower even with it off?

The spa jet water flow can create a venturi that sucks in air past the blower even when it is off.
Show us pics of your equipment pad and blower.

The flow of the water through the venturi creates a low pressure that sucks air into the flow.
