Dry sprinklers that have been in service for 10 years shall be what?

Dry sprinklers that have been in service for 10 years shall be what?

• A. Replaced
• B. Inspected
• C. Tested
• D. Repaired

Answer: (C)

The main idea here is that dry sprinklers have a scheduled, longer-interval check to verify they will operate properly after many years of service. After ten years, a formal test of dry sprinklers is required to confirm the release mechanism and water flow will work as designed. This testing goes beyond a visual inspection because it demonstrates actual operability under system conditions, catching issues like corrosion, debris, or obstruction that could prevent discharge. It’s not about replacing or repairing everything simply due to age; those actions are taken if the test or subsequent inspections reveal a problem. Regular inspections remain, but the ten-year action specifically calls for testing to ensure reliability of the system.
