On the line out of the HD fill bucket just above the water high mark make a small hole when the pump is on it will spit some water out but it will stay in bucket when the pump is off it will let air into the line to stop the siphon. also the line into the sump keep it above the water so you don't siphon back the other way and drain the sump.
