Which NFPA standard is for the installation of standpipe and hose systems?

• A. NFPA 20
• B. NFPA 15
• C. NFPA 14
• D. NFPA 22

Answer: (C)

Standpipe and hose systems are built to deliver water to interior outlets so firefighters can fight a blaze inside a building. The standard that governs how these systems are installed is NFPA 14. It lays out design, installation, testing, and maintenance rules for standpipes, including what types exist (such as wet, dry, or deluge), where hose connections should be located, how piping and risers are sized, and how the water supply and pressure are ensured so water is available on demand at the required levels. It also specifies required components like valves and backflow protection, and it describes the testing and inspection procedures to verify the system’s integrity over time. Knowing this helps you see why NFPA 14 is the one that addresses standpipes and hose systems specifically. The other standards mentioned cover different topics: NFPA 20 is for fire pumps, NFPA 15 for foam systems, and NFPA 22 for water tanks.
