In existing sprinkler systems, which item is allowed under reconditioned equipment?

• A. Reconditioned Sprinklers
• B. Used valves/devices allowed in existing systems
• C. Ordinary Classification
• D. Temperature Ratings

Answer: (B)

In existing sprinkler systems, reconditioning is allowed for items that control or monitor the system, not for the sprinkler heads themselves. Valves and other devices can be reconditioned and reused if they are restored to proper function and meet the standard’s requirements. This keeps the system operable using components that are already in place, while still ensuring reliability. That’s why the correct choice is that used valves and devices are allowed in existing systems. Reconditioning sprinklers themselves is generally not the intended practice, and the remaining options refer to characteristics of the sprinklers rather than reconditioning allowances.
