What does a branch line do in a sprinkler system?

In a sprinkler system, the primary function of a branch line is to connect the main feed, which is often referred to as the main line, to the individual sprinkler heads. This connection is crucial as it allows the water supplied by the main line to reach each sprinkler, ensuring that with the activation of the system, all areas requiring coverage are adequately supplied with water for fire suppression.

The branch line is typically smaller in diameter than the main line, designed to deliver the necessary flow and pressure to each sprinkler head effectively. This arrangement allows for proper distribution of water throughout the designated area, which is essential for the system's overall efficacy in controlling or extinguishing fires.

Understanding this function highlights the importance of properly sizing and installing branch lines in the overall design and efficiency of a sprinkler system. This knowledge is fundamental for anyone involved in the installation and maintenance of fire sprinkler systems.
