ABSTRACT:
A plunger device for forcing waste through a drain line of a plumbing fixture comprising an elongate, tubular member. Fluidly connected to the top end of the tubular member is a valve assembly which is adapted to have a water supply source fluidly coupled thereto. The valve assembly comprises a valve stem which is reciprocally movable between open and closed positions and adapted to block the flow of water from the water supply source into the tubular member when in the closed position. The valve assembly further comprises a check valve for preventing the back-flow of water from the tubular member into the water supply source when the valve stem is in the open position, and at least one air inlet valve for creating a vacuum break when the fluid pressure in the valve assembly is less than atmospheric pressure. Attached to the valve assembly is at least one handle member, while fluidly connected to the bottom end of the tubular member is a plunger member.
