What is a standpipe system?

A standpipe system is a type of fire protection system that is often found in multi-story buildings, such as high-rise buildings, hotels, and hospitals. The system consists of a network of pipes and valves that are designed to supply water to various levels and areas of the building in the event of a fire.

In a standpipe system, the water supply is typically taken from a dedicated water source, such as a water tank or a municipal water supply. The water is then pumped through the pipes and delivered to standpipe outlets, which are typically located in stairwells, hallways, and other common areas of the building.

Standpipe systems can be classified as either wet or dry systems. Wet standpipe systems are filled with water at all times, while dry standpipe systems are only filled with water when the system is activated. Dry standpipe systems are typically used in buildings where the water supply may be subject to freezing, such as in cold climates.

Standpipe systems are typically connected to the building's fire alarm system, which will automatically activate the system in the event of a fire. When activated, the standpipe system will provide firefighters with a ready source of water to use in fighting the fire.

Overall, standpipe systems are an important component of building fire protection systems, as they help to ensure the safety of occupants and minimize damage in the event of a fire.
