ABSTRACT:
A multi-purpose water pressure plunger is provided having a compressible cup defining an interior cavity and having a solid rubber upper portion with a top and a bottom. The cup has an outer wall which extends to form a barrel-like bottom with edges for partially extending into and sealing against walls of a drain opening. The upper portion of the compressible cup has a central passage defined therethrough beginning in a first opening at the top of the upper portion and terminating in a second opening at the bottom of the upper portion. An elongated handle is attached to the top of the upper portion and has a lengthwise aperture therethrough. The water pressure plunger includes a rubber member with a central passage removably and interchangeably attachable to the bottom of the upper portion inside the interior cavity of the compressible cup and to the handle or a valve thereon. The central passage of the rubber member terminates in a nipple-shaped end for fitting into and sealing against a drain opening. A hand-held water pressure plunger is also disclosed which utilizes the removable rubber member and includes a handle portion having a first passage therethrough communicating with a second passage which extends into the rubber member.
