ABSTRACT:
The portable power plunger is for unclogging blocked drains in sinks, toilets, bath tubs and the like. The plunger has a main body having a reciprocating pump with a removable attachment mounted at its outlet lower end which is adapted to cover intimately over the waste water drain of a sink, toilet, or bath tub. The drain may be unclogged by operating the pump to dislodge the blockage and to dispose of it down the sewer. The pump is provided with a substantial back flow preventor such that the dirty water in the drain would not back into the pump to contaminate the latter. An integral injector pipe is also provided on the plunger. The injector pipe extends into an interior compartment at the lower part of the housing between the back flow preventor and the outlet, and it is attached to a pneumatic pressure source or pressurized water supply. The pneumatic pressure or pressurized water provides additional pressure to unclog the blockage in the drain or for drawing dirty water out from the drain.
