Back siphonage definition

Back siphonage means the backflow resulting from pressures lower than atmospheric pressure in the water installation;

Back siphonage means the flowing back of used, contaminated, or polluted water from a plumbing fixture or vessel into a water supply pipe due to a negative pressure in such pipe. (See “backflow”)

Back siphonage means the flowing back of used, contaminated, or polluted water from a plumbing fixture or vessel or other sources into a potable water supply pipe due to a negative pressure in a pipe.
