In sprinkler system design, what term refers to the lines that directly service a number of sprinkler heads from the cross mains?

• A. Branch lines
• B. Risers
• C. Feed Mains
• D. Valves

Answer: (A)

In sprinkler system design, the lines that directly service a number of sprinkler heads from the cross mains are branch lines. Branch lines originate from the cross mains and run out to feed a group of heads, forming the local distribution to that area. They’re distinct from vertical risers (which carry water between levels), feed mains (the main distribution line supplying the system), and valves (which control flow). Branch lines must be sized to supply the required flow and pressure to all heads they serve, and their length and fittings are accounted for in hydraulic calculations to ensure reliable activation of the heads in that zone.
