Drill a small hole, {about 1/8in.}, in your return line. Some drill just below the water line and some just above, depending on what your sump can hold. Drill it on a slight upwards angle, so the water squirts down into the tank.

Clean any build up from the hole, by poking it clean on a regular basis. If the pump shuts down, the siphon break hole will break the siphon, shutting down the back flow of water.



Usually.
