Standpipes Systems

Standpipe System Inspection for Tall Buildings in Southeast MI

Standpipes are typically found in buildings over three stories high and serve as the waterways to move water to the upper floors. Standpipe systems include the pipes, valves, and connections arranged to provide attachment points for fire hoses. The National Fire Protection Association (NFPA) publishes standards that provide requirements for the classification, identification, inspection, testing, and maintenance of standpipe systems. Some standpipes provide only valve connections for the fire department to use, and some provide actual fire hoses at the ready for occupant use.

The annual standpipe inspection is part of your annual fire system suppression inspection, along with its associated components, like valves, rings, and gaskets. If any part is worn or damaged, Arbor Inspection Services can usually include repair, replacement, and installation service on the same day.

Standpipe Inspection for Flow Tests Are Required Every Three Years

A standpipe flow test is required every three years and consists of testing and inspecting all parts, including exercising each connection and valve during water flow. A pressure reading is taken at each connection and valve, and a flow test is measured at the highest point of the building, generally conducted on the building's roof. This ensures that the equipment and the water pressure are sufficient to push enough water to the top of the building during a fire.
