Multiple Choice

Dry sprinklers in service for 10 years shall be?

Explanation:
Testing is the required action for dry sprinklers after they’ve been in service for a long period. Dry pipe systems need a hydrostatic test at the 10-year mark to verify that the piping and valves can still hold pressure and remain watertight. This goes beyond the usual annual inspections, which are about spotting obvious issues and ensuring general readiness. Replacement isn’t automatically required at 10 years, and repairs would only be needed if the test or inspections reveal a problem. So the 10-year requirement is to perform a formal test to confirm the system’s integrity, making testing the correct choice.
