Which standard governs flushing of underground piping supplying a standpipe system?

• A. NFPA 25
• B. NFPA 24
• C. NFPA 13
• D. NFPA 70

Answer: (B)

The test focuses on which standard covers the installation and related commissioning steps for underground piping that feeds a standpipe system. Flushing of that underground main is addressed in NFPA 24, which covers private fire service mains and their appurtenances, including underground piping, flushing to remove debris, and subsequent charging and testing of the line. This ensures the path to the standpipe is clean and ready for operation before water is placed into the system. NFPA 25 deals with inspection and maintenance after installation, NFPA 13 covers sprinkler systems, and NFPA 70 is the Electrical Code, so they do not govern the initial flushing of underground supply piping.
