back-siphonage the flowing back of used, contaminated, or polluted water from a plumbing fixture or vessel into a water supply system due to negative pressure in such pipe.(see backflow) (if an open supply outlet in the system is in contact with contaminating material at the time the pressure becomes negitive, back-siphonage can draw contamination into the supply system. negitive pressure is any pressure thats less than atmospheric pressure, which is approximately 14.7 psi at sea level.)
