Abstract: Provided herein is a plug that is configured to obstruct an auxiliary inlet of a garbage disposal, and more particularly, to a manually removable plug for an auxiliary inlet of a garbage disposal that precludes attachment of a drain hose from a dishwasher to the auxiliary inlet without removal of the plug. Embodiments may include a garbage disposal including a grinding chamber with a primary inlet and an auxiliary inlet. Embodiments may include a plug for obstructing the auxiliary inlet of a garbage disposal. The plug may include a plug body, a stem, and a handle, where the stem extends between the plug body and the handle. The plug body may define a cylindrical shape having a diameter axially aligned with an axis of the stem. The handle may define a first edge, second edge, and a length defined there between extending perpendicularly to the axis of the stem.
