I think I need some fairly urgent help here.
I just bought this house, with pool, this Spring. The [uphill] pump has been OK, I think (21psi) .
Yesterday, I noticed my pump (Hayward super pump - 2hp, 1.0sf) is 'screaming' much louder than usual.
So, I turn it off, & it sounds/appears to be forced to run backward for a second or two ! The pressure guage on the multiport valve is still showing 21psi, as usual.
I opened & cleaned the pump filter basket. This caused me to lose prime, as usual.
When I turn the pump back on, it does not get loud until it gets prime (full of water) ?!?
Also, I notice that the returns are now alternately spewing a little air in with the water. It appears that 2 of the 3 are doing it at any given time.
I do not see any water leaks around the pump.
I'm sure you experts here immediately recognize this problem.
I would be most appreciative of a [quick] solution !
