What is the function of a riser in a sprinkler system?

The function of a riser in a sprinkler system is to transport water vertically to sprinkler heads. Risers are essential components that facilitate the movement of water from the lower sections of the system, such as the main supply, to the upper areas where the sprinklers are installed. This vertical transport is critical for ensuring that the entire system can operate effectively by delivering the necessary water pressure and flow to each sprinkler head, allowing them to function as intended during a fire event.

In a properly designed sprinkler system, the riser plays a pivotal role in maintaining the overall integrity of the water distribution process. It allows access to the upper floors of buildings, ensuring that fire protection is provided where it is most needed.
