Well... after spending hours and hours trying to troubleshoot... I find myself here on TFP!
Situation:
I have this pump:
Hayward SP2300VSP Max-Flo VS Variable-Speed Pool Pump
I have run a drain bladder to both the inlet and outlet sides and I have flow (no obstructions). The RPM on the VSP is showing as indicated. In my case I have three settings 1000RPM, 2400RPM and 3000RPM. However I am not getting nearly the suction at the strainer or the vac (the pool only has a strainer so the vac goes into the inlet at the base of the strainer housing.
The gauge on the Jandy shows pressure, but is suspect as far as condition.
I removed the motor from the impeller housing, removed the three screws that secure the impeller and everything looks as it should. (clean, etc.)
I have not replaced any seals (o-rings) etc. since the pump was put in service in April 2014. So I am uncertain if that is a factor. I have put a some grease, etc. but no difference to performance.
Is this a no brainer? "Do the impeller, and rings, stupid Pete" -- or... is there more? Could it be the O-ring on the Jandy side? Something else I might be overlooking. There isn't even enough vac to move the indicator that comes with the Great White. So it's loooooooow.
The sight glass on the Hayward is about 2/3 full not NOT right up to the underside of the clear plastic. No unusual noises.
Thoughts and ideas very appreciated.
Pete
