Hey everyone, I'm sure this question has been asked before so please forgive me in advance. I'm getting alot of air bubbles in my pump housing stainer pot, the pump can run for hours and they never go away, I wouldn't be to concerned with it except there is alot of air in the pot. Does this mean it's pulling air from somewhere before the pump, maybe a fitting or something. It hasn't been to long since i changed the pump...I have a 25,000 gallon in ground pool, vinyl liner, 1.5 h.p. pump, sand filter....Thanks in advance for the answer....James....
