Stand Pipe

Standpipe systems are a series of pipes which connect a water supply to hose connections, basically an extension of the fire hydrant system. They are designed to provide a pre-piped water system for building occupants or the fire department. Standpipe systems are designed to provide fire protection water for hose lines in strategically placed locations inside a building or structure.

Description

There are three classes of standpipe systems:

Class I – A Class I standpipe system shall provide a 2-1/2 inch hose connection for use primarily by trained personnel or by the fire department during initial response. This class has no hose attached. The fire department will usually carry hose packs to the floor level, typically a stairwell, where they will start their operations and connect to the standpipe system. These connections must match the hose thread utilized by the fire department.

Class II – A Class II standpipe system shall provide 1-1/2 inch hose stations to supply water for use primarily by trained personnel or by the fire department during initial response. These are typically found in cabinets with 100’ of hose.

Class III – A Class III standpipe system shall provide 1-1/2 inch hose stations to supply water for use by trained personnel and a 2-1/2 inch hose connection to supply a larger volume of water for use by fire departments and those trained in heavy fire streams. Many times these connections will provide a 2-1/2 inch reducer to a 1-1/2 hose connection.
