Which statement is true about reconditioned sprinklers?

• A. Allowed in existing systems
• B. Not allowed in new or existing systems
• C. Allowed in new systems only
• D. Required to be listed

Answer: (B)

Reconditioning a sprinkler changes its characteristics and essentially voids its original listing. Sprinklers used in fire protection systems must be listed and installed as tested by the manufacturer. Because reconditioned sprinklers no longer carry the original listing and their performance (spray pattern, temperature rating, reliability) can be unreliable, they are not permitted in either new construction or existing systems. In practice, you replace with new, listed sprinklers rather than reconditioning old ones. The other options imply that reconditioned sprinklers have some permitted use in certain situations, which conflicts with the requirement for a listed, tested product in all installations.
