  • a plunger head fixed to the shaft adjacent the other end thereof;

    said shaft being substantially nonextendable axially, and of a length to position said hand gripping portion generally above the top bowl edge opposite the outlet passage while said head is fitted in the bowl outlet passage;

    said plunger head being made of an impervious flexible material that is also resilient and elastic;

    said plunger head defining a maximum exterior surface larger than the bowl outlet passage, operable as the plunger is fitted into the bowl passage in the mode of a piston, to be automatic reshaped radials inward and outward as needed locally to present an annular region substantially seated against the bowl passage wall so as to substantially block the bowl outlet passage;

    whereby axial shifting of the shaft concurrently shifts the plunger head axially in the bowl passage, operable to hydraulically force water/waste in the outlet passage axially thereof to serve to break up blockage in the outlet passage downstream thereof.
