Installed new Hayward 3/4 hp pump and basket to replace old 3/4 hp pump for an in ground pool. The basket does not fill completely as the water level is about 2" below the top of the lid. Both the inlet and outlet lines are 1 1/2". I did not have this problem with the old pump.
When I installed the new pump I had to cut some of the 1 1/2" inlet pipe off. The inlet pipe comes out of a tee that is connected to two valves. The inlet pipe is only about 4" before entering the pump.
Is this too short of a inlet run before the pump? Would this be causing the problem? If so, how much more do I need to extend the inlet line?
