What is a wet stand pipe and dry stand pipe?
Wet standpipe A “wet” standpipe is filled with water and is pressurized at all times. In contrast to dry standpipes, which can be used only by firefighters, wet standpipes can be used by building occupants. Wet standpipes generally already come with hoses so that building occupants may fight fires quickly.
Do I need a standpipe?

Within the context of a building or bridge, a standpipe serves the same purpose as a fire hydrant. In many other countries, hydrants in streets are below ground level. The standpipe is then “sunk” into the hydrant, and the hose is connected to the exposed ends of the standpipe.
How are standpipe systems used in fire protection?
Standpipe systems are designed to provide fire protection water for hose lines in strategically placed locations inside a building or structure. Some older buildings only have standpipe systems while many newer buildings will have a combination system, which supplies the fire sprinkler system and the standpipe system.
How is a standpipe connected to a fire hydrant?

What are standpipe systems and fire hose angle valves?
Refer to NFPA 14: Standard for the Installation of Hose and Standpipe Systems for more information. Fire hose angle valves (sometimes called angle hose valves) attach to standpipe systems and provide firefighters with a connection to water from inside the building. They eradicate the need for lengthy hose lays within tall buildings.
