  • Patent number: 5236137
    Abstract: An apparatus and method for cleaning and flushing a conventional garbage disposal unit. A flow restricting valve replaces a conventional valve in the water seal trap in a kitchen drain line. The flow restricting valve is actuated by a pull-push plunger from outside the pipe. To clean the garbage disposal, the valve is closed and water back flows into the disposal unit for cleaning. When the valve is opened the garbage disposal unit can be flushed. Accordingly, the garbage disposal unit is easily cleaned and flushed, eliminating undesirable odors, without the need for a plumber's intervention.
