I just had my pool reconstructed by a pro and installed the new filter and pump myself (i feel i'm fairly handy). The pool contractor said that even though my pool was really old, the line seemed in good shape and not necessary to change...they are 1.5 inch copper. Anyway, the pump is a Whisperflo 1hp with 2 inch in/out and the filter is a Hayward sand 24inch 244T. My question is should this pump work ok with the smaller lines? The pump basket doesn't fill with water (is this normal)and i'm getting a lot of air back into the pool via the returns. When I turn the filter off the water in the filter and pump gravity feeds back to the pool. Should I install a check valve to prevent this?
Hope this makes sense and any help is appreciated.
