Which NFPA section is cited for the inspection of sprinkler pressure-reducing valves in the source material?

• A. 5-2-6
• B. 14-4-3
• C. 14-2-13-3
• D. 13-5-1-1

Answer: (D)

Understanding the rules for inspecting components on the water supply side is what this tests. Pressure-reducing valves are critical control devices that set and maintain the correct pressure for sprinkler piping. Regular inspection and testing ensure they operate as intended and don’t drift out of calibration, which could overload or starve the system. The source material cites NFPA section 13-5-1-1 for the inspection of sprinkler pressure-reducing valves. That specific section is the one that addresses how and when these valves should be inspected and tested, making it the best reference for this topic. The other listed sections pertain to different aspects of sprinkler systems and do not address PRV inspection in the source material.
