the empeller screw, is that a rubber washer that's used?

Hi, Phillip. Yes, the impeller screw uses a rubber washer.

What if the impeller screw plastic housing cracks and you can only use the remaining screw without the o-ring and plastic housing. Will that result in the pump leaking from the bottom of the housing after its installed?

A  Answered on 10/29/2018 by InyoPools Product Specialist Lennox H.

Hi, David. The pump will not leak if the o-ring is not used based on the B2842 motor that you're using. That motor is designed to work with or without an Impeller screw.

I have a new USQ1202 motor. My impeller screw and associated rubber gasket are broken. Are they needed with this motor?

A  Answered on 11/18/2020 by InyoPools Product Specialist Hector F.

Hi Mike, could you send us a few photos of your pump? Ideally, a wide shot showing the complete pump, including where the pipe goes in and out of the pump, and a second close-up photo of the motor label. This would help us determine the proper replacement.
