Claim:
A flush cartridge apparatus for use in the removal of debris from a potable water distribution system, comprising: an elongated, cylindrically shaped, hollow body having a first outer diameter and an axial passageway having an inner diameter; a first end portion of said cylindrically shaped, hollow body being designed for primary insertion into a housing opening in a plumbing valve housing used in a potable water distribution system, said first end portion having an outer diameter equal to the first outer diameter of the hollow body and further having a central orifice therein; an elongated mid-portion of said cylindrically shaped, hollow body being designed for secondary insertion into the housing opening, said elongated mid-portion being affixed to said first end portion and having an outer diameter equal to the first outer diameter of the cylindrically shaped, hollow body, said mid-portion further having a cold water inlet port and a hot water inlet port, said inlet ports being positioned axially disposed from one another in said mid-portion, wherein the inlet ports provide fluid and debris flow from the potable water distribution system in to the internal, axial passageway, said mid-portion further having a plurality of circumferential, radial grooves in an external surface of said cylindrically shaped hollow body, wherein each of said circumferential, radial grooves are adapted for the mounting of an o-ring seal member therein for sealing engagement of said cylindrically shaped hollow body within an inner diameter receiving surface of the plumbing valve housing to generally prevent fluid and debris flow between the outer diameter of the cylindrically shaped hollow body and the inner diameter receiving surface of the housing opening; and a second end portion of said cylindrically shaped hollow body being affixed to said elongated mid-portion and wherein the mid-portion is disposed between the first end portion and the second end portion, said second end portion providing an outlet for said internal, axial passageway to allow the complete discharge of debris from the potable water distribution system.
