ABSTRACT:
A multi-purpose water pressure plunger employs a source of pressurized water to dislodge clogs in bathroom drainage pipes and the like. The plunger is fashioned of a resilient cone-shaped cup, a rigid handle, an adjustable valve, and a means of connection to a pressurized source of water. Sealing against and partially extending into a drain opening, the cup permits full thrust of pressurized water into a drainage pipe without a backflow of water. The cup consists of an upper, deformable portion, and a solid, occlusive bottom portion defining a nipple-shaped end. A flow of pressurized water is supplied to the cup through an elongated and ridged handle with a lengthwise aperture therethrough. An adjustable valve including a ball component and a regulating lever controls the flow of water into the handle, and thus, to the clogged drain.
For oddly-shaped and rounded drainage openings, the multi-purpose water pressure plunger has a sealing attachment including a compressible cup having a barrel-like bottom and an occlusive semi-spherical disc. When inserted, the barrel-like bottom partially extends into a drainage opening, and when pressed downwardly, the semi-spherical disc seals the barrel-like bottom against walls of a drainage opening, and the perimeter of the compressible cup envelopes around the barrel-like bottom.
