I installed an electric pump also. I ran the hose from the pump out of the bilge, under the port setee, and teed into the sink drain. The tee should be close to the sink to prevent water from coming in when heeled. As long as the drain in the sink is not plugged, it will work as a siphon break. I used a Rule pump and float switch. I did not install a check valve, and did not have problems with short cycling.
