Dry sprinklers that have been in service for how many years must be replaced or tested?

The requirement for the replacement or testing of dry sprinklers after being in service for a specified number of years is based on industry standards to ensure reliability and performance. The correct answer is that dry sprinklers must be replaced or tested after 10 years.

This time frame is established to account for the potential degradation of materials and components within the sprinkler system, which can be affected by environmental conditions, such as temperature and humidity. Over time, seals and other materials can deteriorate, possibly leading to failures when the system is needed for fire protection. Regular testing or replacement at the 10-year mark minimizes the risk of malfunction during an emergency, maintaining the overall effectiveness of the sprinkler system.

By adhering to this 10-year guideline, facilities can ensure that their fire protection systems remain reliable and compliant with applicable codes and standards, ultimately contributing to the safety and security of the environment they protect.
