Any thoughts on this...
I did a routine back flush on my pool today and when I switched the valve from back wash to filter found that my pool cleaner (zodiac G4 was no longer working). After a quick check found that the flow keeper valve was open and would trip every time after resetting and there was noticeably more suction than usual. I checked the pressure gauge at the filter and psi was at 19.5. i have tried back washing with a rinse several times with no change. Pump is wired for 120 and I confirmed 120 volts at motor connections with a voltmeter. I pulled the flow valve off to inspect internals and sand, both ok. I am guessing it has to be something simple but at this point not sure what to do.
The filter psi usually runs at 8psi and I usually back flush once a week or when the pressure raises to 12-14psi, today was no different with pressure at 12psi before back flush.
Filter (Jacuzzi L250C) and sand were replaced 2 years ago, Pump (Hayward Super Pump 1 1/2HP) was replaced this year.
Suction at skimmer inlet and outlet at the two returns in the pool are more noticeable (both suction and fore from the returns increased.
Seems like something is off with the pump to me, ideas?
