Abstract
A water line decontamination unit has inlets for connection to a supply of irrigant liquid, a supply of disinfectant, and a pressurized gas supply, and an outlet for connection to a water line inlet. A valve assembly in the unit controls the supply of irrigant liquid, disinfectant and gas to the water line so that only one of the fluids is supplied to the water line at any one time. A manual selector allows an operator to select a run condition in which irrigant liquid is supplied to the water line, a flush condition in which disinfectant is supplied to the water line, and a purge condition in which gas is supplied to purge liquid from the water line.
