ABSTRACT:
A toilet plunger comprises a resiliently deformable plunger element, a tubular handle element which is connectable to a supply of pressurized water, a shutoff valve on the handle element, and a check valve element for preventing the inadvertent backflow of fluids through the handle element. The toilet plunger is operable for applying increased pressure to an obstruction in the outlet portion of a toilet or in a drain line by supplying pressurized water to the plunger element through the tubular handle element, and it is alternatively operable as a conventional toilet plunger by positioning the plunger element over the outlet portion of the toilet or drain line and reciprocably moving the handle element toward and away from the plunger element. The check valve element prevents the backflow of fluids through the handle element in the event that the shutoff valve is inadvertently left in an open position when the plunger is reciprocally operated as a conventional toilet plunger.
