In NFPA 25, how often should the interior of sprinkler piping be visually inspected?

• A. Every 3 years
• B. Every 5 years
• C. Annually
• D. Every 10 years

Answer: (B)

The correct interval for visually inspecting the interior of sprinkler piping, as outlined in NFPA 25, is every 5 years. This requirement is in place to ensure that the integrity of the sprinkler system is maintained and that any potential issues, such as corrosion or debris accumulation, can be identified before they affect system performance. Regular inspections help to ensure that the sprinkler system will operate effectively in the event of a fire, meeting the safety and reliability goals of the fire protection system. Visual inspections every 5 years allow for a comprehensive assessment while balancing practicality and safety. Shorter intervals, such as annually, could be excessively burdensome without providing significant benefits, while longer intervals, such as every 10 years, may not address deteriorating conditions in a timely manner. Thus, the 5-year requirement strikes an appropriate balance to ensure that the system remains in good working order, consistent with the objectives of NFPA guidelines.
