ABSTRACT:
The toilet bowl drainage pump includes an elongate housing having a curved forward end from which a length of tubing extends and in which a plurality of openings are cut at a larger diameter of the curve. A motorized impeller is seated within one chamber in the housing into which the openings lead and out of which the tubing leads. A power source for the motor is provided in a second isolated chamber is selectively operable to energize the pump. In use, the tubing is fed through and over a drain trap of the toilet bowl as the forward end of the housing is seated along a bottommost surface of the bowl. The motor is then activated to pull water into the housing openings and eject the water throughout the tubing.
