A water deluge system cleaning apparatus and method of cleaning a water deluge system which does not require the water deluge system to be offline while it is being cleaned. This is achieved by a packing device (23) that provides an annular seal within the water deluge sys¬ tem, and a cleaning device (25) for cleaning the water deluge system that extends through the packing device.
