An unclogging system for the plumbing of a sink/garbage disposal assembly including a water supply line, a sink drain waste line, a garbage disposal waste line, and an end-outlet tee having a first inlet, a second inlet connected to the sink drain waste line, and an interior baffle disposed adjacent to the first inlet. The system includes a coupling adaptor having a waste-in end attached to the garbage disposal waste line, a waste-out end attached to the first inlet, a hollow interior for the passage of fluid/waste therethrough, and an inlet port. A water jet tube extending through the inlet port into the interior directs water toward the waste-out end and at the baffle. A solenoid valve allowing a flow of water from the water supply line to the water jet tube is coupled to a power outlet, which simultaneously powers the solenoid valve and the garbage disposal.
