the half round piece of plastic may restrict flow a tiny bit, but it has a main function. GE's fill on a timed fill. Depending on water pressure, the tub may not fill all the way. the plastic piece helps by lowering the "suction point" of the pump in order to prevent as much cavitation as possible. GE's pumps are high volume pumps, and with a shallow sump, they will cavitate like hell. listen for a rythmic pulsing of the motor.......that's cavitation.
