My pool pump motor is running -- the air is blowing out of the pipe in the deep end and making a noise -- but it is not coming out at the shallow end -- don't know the name of the pipe but its an aerator... circulating the water. Anyway I think it means the pump is going bad ... but not out altogether since its trying to work at the deep end. I have the motor turned off now.

Is there anything else that would make it act like that? I know we have replaced the pump motor in the past -- but don't think we had to replace the pump. My late husband took care of that....I have a call in to the company that I usually use but haven't heard back. Went online to a local company that sells equipment and all I could find was pumps with motors .

Any help in diagnosing the problem would be welcome.
