Standard everyday street fire hydrants are provided with a plurality of threaded outlets to which hoses may be connected (by far the most common is 2.5" NH/NST). Common fire standpipe valves range from 1.5" NH/NST to 2.5" NH/NST. A cap is mounted over each outlet for closing off outlets and a cap is removed when a hose is to be connected thereto.
