See my sig for setup.
The basket isn't completely filled. I can see the horizontal "column" of water entering the basket from the inlet pipe (supply is 1.5", exit is 2"). I'm not talking bubbles like from cavitation, it's just not filled and is stable like this while running.
Skimmer looks well filled, if anything pool level is too high (recent rains). It seems unlikely air's entering from there and the air condition is not intermittent.
I checked that the basket cover is well seated on clean o-ring.
I estimate pump is 22' from pool. Pool has single bottom drain and single skimmer on end of pool nearest pump.
Pump seems pretty noisy too.
Is the pump too big for the inlet plumbing? I've been considering reducing to 3/4 HP SF 1.27 or even SF 1.
Any thoughts on what's going on or what to check.
Thanks so much for your help!
