Which statement is true regarding the use of reconditioned valves and devices in existing systems?

• A. Not permitted
• B. Permitted
• C. Permitted only with written approval
• D. Prohibited except by manufacturer

Answer: (B)

Reconditioning valves and devices can be used in existing sprinkler systems. Restoring a component to like-new condition helps maintain system function while avoiding the higher cost and downtime of replacing it with new parts. Before installation, the reconditioned item should be brought back to its original specifications, tested to the system’s operating pressure, and inspected for leaks, wear, or any compatibility issues with the piping and materials. It should also carry the proper labeling and meet the applicable standards, with work performed by qualified personnel following manufacturer instructions. While some jurisdictions may require written approval or confirmation from the manufacturer, the general practice supports using reconditioned components, so they are permitted.
