NFPA Standard most often used by codes for installation of standpipe is NFPA ______?

• A. NFPA 13
• B. NFPA 101
• C. NFPA 25
• D. NFPA 14

Answer: (D)

Standpipes are dedicated piping within a building that brings water to a firefighting operation, so the codes rely on a standard that specifies how these systems must be installed. That standard defines the types of standpipes (Class I, II, III), their placement, hydraulic requirements, outlets, pressures, and testing/acceptance criteria, ensuring a reliable water supply and proper integration with the building’s protection plan. NFPA 14 is the standard that covers all of these installation details for standpipes, which is why it’s the one most often referenced by codes for standpipe installation. In contrast, NFPA 13 governs sprinkler system installation, NFPA 101 focuses on life-safety code provisions rather than installation specifics, and NFPA 25 deals with inspection, testing, and maintenance of water-based systems after installation.
