METHOD AND SYSTEM OF REMOVING DEBRIS FROM PIPING IN A HIGH-RISE BUILDING PLUMBING NETWORK

摘要

A method and system for removing debris from drainage lines in high rise building uses a high pressure water line terminated by a head having one or more backwards-facing nozzles. The thrust force creates at the backward-facing nozzle(s) is sufficient to propel the head and water line vertically up a drainage line. An operates can control the head and, with the assistance of a video system used with the head, maneuver the head along the line, into single stack aerator fittings, and into and along horizontal lines connected to the single stack aerator fittings. The force of the water exiting the nozzle(s) on the head both dislodges debris in the drainage line and fittings, and urges it downstream back to the access point where the head was inserted into the drainage line.
