What typically marks the transition from underground piping to interior piping in a sprinkler system?

• A. Cross Main
• B. Feed Main
• C. Sprinkler Riser
• D. Branch Line

Answer: (C)

The transition from underground piping to interior piping in a sprinkler system is typically marked by the sprinkler riser. This component serves as the point where the system moves from the underground infrastructure to the above-ground system, facilitating the distribution of water to the various branch lines and sprinklers throughout the building. The riser is crucial because it not only connects the underground supply to the interior network but also often includes valves, gauges, and connections for fire department connections or system testing. It is designed to handle the pressures and flow dynamics necessary to ensure effective sprinkler operation once the water moves into the building. Understanding the function of the riser helps emphasize its importance in maintaining system integrity and operational efficiency.
