Which term describes a sprinkler system where cross mains run parallel and are interconnected by multiple branch lines?

• A. Grid
• B. Radial
• C. Loop
• D. Ring

Answer: (A)

Grid piping layouts describe networks where cross mains run parallel and are interconnected by multiple branch lines. This arrangement forms a grid pattern that provides multiple paths for water to reach each sprinkler head, improving hydraulic balance and offering redundancy if a line is shut down. It’s different from a radial system, which radiates from a single supply point outward without the parallel cross mains. A loop or ring describes a closed circuit that returns to the source, giving alternate routes, but it does not capture the characteristic interwoven parallel mains with many interconnections that define a grid.
