When sprinklers have been on service for 50 years, what shall they be?

• A. Retested
• B. Replaced
• C. Repaired
• D. Retired from service

Answer: (B)

Long-term aging of sprinkler heads introduces reliability risks. After about 50 years in service, corrosion, fatigue, and wear can affect how a head activates and distributes water, making it less predictable in a real fire. Replacing the sprinklers at this age ensures you have up-to-date hardware with predictable performance, reduces the chance of failure, and aligns with common fire protection practice and standards. Simply retesting or repairing aged heads doesn’t address the underlying deterioration, and retiring them without replacement would leave the system unprotected.
