I just replaced the diffuser O-ring and seal plate ring gasket (thanks to Pool Clown and dbfan for advice on that project). My problem is that when I powered up, the thing is still leaking from looks to be underneath under the motor, not the seal plate. The trap basket lid and drain plug O-rings are newer and still in fine shape.
I think the only thing left that can be leaking is the shaft seal. Before I go through the process of ordering parts again, is there anything else I should be inspecting? Could the new leak be residual water left in the motor housing from a leaky diffuser O-ring? I didn't let it run for very long.
This is a Sta-Rite DuraGlass pump P2RA series
