Step 8 · Final Checks and Testing

With everything connected, it's time to test your work. Plug the disposal's power cord into the switched outlet under the sink. Place the sink stopper in the drain and fill the sink basin about halfway with cold water. Lay dry paper towels on the bottom of the cabinet under all the new pipe connections. Now, remove the sink stopper to let the water rush down, and immediately turn on the wall switch for the garbage disposal. While the water is draining and the disposal is running, use a flashlight to carefully inspect the sink flange, dishwasher connection, discharge tube, P-trap, and all slip nuts for any signs of dripping. If you find a leak, turn off the disposal and water, and tighten the leaking connection slightly.
