A Fire Department Connection (FDC) is a connection on the exterior of a commercial building where a responding fire department can attach a fire hose to pump water into the building's stand pipe. This supplements the water pressure of a building's existing system.
A traditional FDC connection consists of a brass fitting in the shape of a "Y" protruding from an outside wall of the building. This is known as a "siamese" valve. It has two 2 1/2" female fittings that flow water into one 4" pipe located in the interior of a wall.
