How far should an FDC be from a hydrant?
FDCs shall be no more than 150 feet from a public hydrant. The FDC may be located within 150 feet of a private hydrant if the FDC is connected to the fire sprinkler system by a dedicated pipe that connects on the system side (i.e., downstream) of the sprinkler system check valve.
