ABSTRACT:
Specifically, the present invention is a flush cartridge apparatus used in the controlled removal of accumulated debris from a water distribution system used within a residential and/or commercial structure. The flush cartridge apparatus is generally cylindrically shaped and is designed for sealed engagement within a plumbing valve housing, including pressure balance valves and mixing valves, to provide a long, sustained and complete flushing of water and debris from the water distribution system, while generally preventing water damage, and the occurrence of mold and/or mildew, within the structure. The flush cartridge apparatus can be used alone or in combination with other plumbing tools depending upon the specific need. The flush cartridge apparatus includes alignment and mating features for improved control and safety while using the apparatus.
