• A. Grid
• B. Loop
• C. Standby network
• D. Pressure relief system

Answer: (B)

Redundancy in fire sprinkler piping is achieved with a looped layout. In a loop, the supply piping forms a closed path so if a section is taken offline for repairs, water can still reach all parts of the system by flowing around the loop from the remaining sections. This setup helps maintain steady pressure and adequate flow to sprinklers despite work on the grid, reducing the risk of drops in pressure that could leave some heads unable to operate. The loop provides an alternate route for water, balancing losses and ensuring reliability during maintenance. A generic grid doesn’t specifically describe this built-in redundancy, a standby network refers more to an alternate source that can be brought online during outages rather than to maintaining flow during repairs, and a pressure relief system is about preventing overpressure rather than preserving service during repairs.
