What are risers in the context of a sprinkler system?

Risers in a sprinkler system refer to vertical supply pipes that transport water from the main supply line to various levels of the building or facility. These vertical pipes are essential in distributing water efficiently to the sprinkler heads located on different floors. In multi-story buildings, risers ensure that each level receives appropriate water pressure and flow necessary for effective fire suppression.

By serving as the primary conduits for water, risers help maintain the system's functionality under varying conditions, such as different heights and building layouts. Their design and proper installation are critical for compliance with fire safety codes and ensuring that the sprinkler system operates effectively in case of a fire emergency.
