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

• A. Replaced
• B. Repaired
• C. Retested
• D. Reconditioned

Answer: (A)

When sprinklers have been in service for 50 years, they should be replaced. Over many decades, corrosion, material fatigue, and degradation of sealing elements can compromise a sprinkler’s ability to respond and discharge water as designed. Replacing ensures the heads meet current listing and performance standards and provides reliable operation of the system. Repairing or reconditioning old heads cannot guarantee the original performance and is not considered acceptable for life-safety sprinklers. Retesting is part of normal maintenance, not the required action at the 50-year mark.
