Abstract : An automatic flushing apparatus for vacuum flow system urinals. A pressure sensing switch responds to the hydrostatic pressure resulting from one or two urinations and directs the system vacuum to both a water dispensing valve and the main discharge valve to automatically flush the system with a measured amount of water to prevent odors and soil drain scale buildup.
