<p>The invention provides a method and apparatus for treating a deluge system. The apparatus comprises a venturi device comprising a first inlet and an outlet for connection to a flow path between a firemain and an arrangement of deluge pipework. The venturi device, which may be an eductor or inductor, comprises a second inlet for connection to a source of corrosion inhibitor. A corrosion inhibitor control valve actuable between an open condition in which corrosion inhibitor is drawn into the deluge pipework by motive fluid in the flow path, and a closed position in which the deluge pipework is isolated from the source of corrosion inhibitor.</p> |
