What should be done if sprinklers are painted by someone other than the manufacturer?

When sprinklers are painted by someone other than the manufacturer, the most appropriate action is to replace the affected sprinklers. This is because painting can interfere with the sprinkler’s performance and effectiveness. Sprinklers are designed and tested to operate under specific conditions, and any alteration, such as painting, can inhibit their ability to function correctly during a fire event.

The original finish on a sprinkler head serves important purposes, including proper heat transfer and activation at designated temperatures. If the head has been painted, it may not activate as intended, potentially allowing a fire to spread unchecked. Therefore, replacing the painted sprinkler heads is crucial to maintain the integrity of the fire protection system.

Ensuring that all sprinklers remain in their original condition as provided by the manufacturer is vital for safety and compliance with fire codes and standards. The replacement of non-compliant equipment is a preventive measure to ensure the effectiveness of the sprinkler system in emergencies.
