From reading other posts, I think have a suction side air leak. I have many many bubbles in the pool coming through the return jets, and a small whirlpool in the pump basket. I have lubed the pump basket O-ring and the plugs at the bottom of the pump. The water level in the pool is good. I turned off and disconnected my pool cleaner to eliminate the hose as a possible source of air. I give up. Anything more than this is beyond what I can do. So what type of company do I call to help me find this air leak? Is this something that any pool repair company should be able to find and fix?
