ABSTRACT:
An overflow valve system (10) comprises a tubular housing (12) having a J-shaped pipe fitting (14) mounted therein having an injection nozzle (24) at a first pipe-fitting end (26) located in a housing bore (40) of the tubular housing near the bottom thereof for injecting liquid axially upwardly in the housing bore and having a second pipe fitting-end (30) located outside of the tubulary-shaped housing (12). The injection nozzle has female threads therein for meshing with male threads of a toilet-flush ballcock (18), said threads meeting national standards for threads on ballcock shanks and nuts for water-closet bowls, tanks and urinals whereby a standard water-closet ballcock can be sealingly mounted in the overflow valve system by screwing it into the nozzle for controlling the flow of water through the pipe fitting into the bore. The overflow valve system further includes a bracket (16) attached to the wall of the tubulary-shaped housing for hanging the overflow valve system on the wall of a tank in which liquid level is to be controlled.
