Lot's of companies have tried to improve this simple design by making it more complicated for no additional benefit. 6.8.2 The sign shall be located at the water supply control valve for automatic or semiautomatic standpipe systems and at an approved location for manual systems. There are two designs for a standpipe system: the older pipe schedule method and hydraulic design. a standpipe system. This section also states that a standpipe system does not have to be sep-arate from an installed sprinkler system. It is common practice in mul-tistory buildings for the standpipe system risers to also serve as risers for the automatic sprinkler systems. In these instances, pre-cautions need to be tak-en so that the ... A standpipe system permanently attached to a water supply capable of supplying the system demand at all times, containing air or nitro- gen under pressure, the release of which (as from opening a hose valve) opens a dry pipe valve to allow water to flow into the piping system and out of the opened hose valve. Feb 29, 2020 · A standpipe system is a fire safety system which is designed to provide rapid access to water in the event that a fire breaks out. Standpipes are installed as standalone systems which act like building-specific fire hydrants, providing fire protection which will be readily available to fire fighters. Water System Design Manual (PDF, DOH 331-123) Revised 2019. The design manual is a start-to-finish reference for engineers and others involved in water system design.
