Standpipes are vertical pipes that are installed in buildings to provide a supply of water to firefighters in case of a fire emergency. The standpipe system consists of a network of pipes and valves that are connected to a reliable source of water, such as a municipal water supply or a fire pump.
The standpipe system typically has outlets, called standpipe connections, at various locations throughout the building, such as on each floor, in stairwells, and in mechanical rooms. Firefighters can connect their hoses to these standpipe connections to access the water supply and fight fires from inside the building.
In addition to firefighting purposes, standpipes can also be used for routine maintenance and testing of the building's fire protection systems. Regular inspection and testing of standpipes can help ensure their reliability in the event of an emergency
