Abstract:
A wet pipe fire protection sprinkler system and method of operating a wet pipe fire sprinkler system includes providing a sprinkler system having a pipe network, a source of water for the pipe network, at least one sprinkler head connected with the pipe network and a drain valve for draining the pipe network. An inert gas source, such as a nitrogen gas source, is connected with the pipe network. Inert gas is supplied from the inert gas source to the pipe network. Water is supplied to the pipe network thereby substantially filling the pipe network with water and compressing the inert gas in the pipe network.

Claim (Index 7):
A method of operating a wet pipe fire protection sprinkler system having a pipe network, a source of water for the pipe network, at least one sprinkler head connected with the pipe network, and a nitrogen source connected with the pipe network, the method comprising:\n supplying nitrogen gas from the nitrogen source to the pipe network to increase a pressure in the pipe network to greater than atmospheric pressure and less than 50 psig; discharging gas from the pipe network after supplying nitrogen gas to the pipe network; supplying water to the pipe network after discharging gas from the pipe network, thereby filling the pipe network with water and compressing nitrogen gas in the pipe network; and venting compressed nitrogen gas from the pipe network using a venting assembly configured to vent gas and not water from the pipe network while supplying water to the pipe network.
