After testing sprinklers for the first time, when should testing be repeated?

The correct answer is that testing should be repeated every 10 years. This timeframe aligns with industry standards and regulations that are set to ensure the reliability and effectiveness of sprinkler systems. Regular testing is critical to identify any potential failures or degradation in sprinkler performance over time due to factors such as corrosion, obstruction, or mechanical issues.

Conducting tests every 10 years is a widely accepted interval that balances safety, regulatory compliance, and practicality. It allows enough time for visual inspections and functional tests to reveal any changes or problems while ensuring compliance with safety codes that are designed to protect lives and property. Adhering to this schedule helps maintain the integrity of fire protection systems and ensures they operate effectively when needed.
