When should fire sprinkler valves be tested for functionality?

Fire sprinkler valves should be tested for functionality during annual inspections to ensure that the entire fire protection system operates correctly and reliably when needed. This annual inspection is a critical opportunity to check the valves alongside other components of the fire sprinkler system to identify any issues before they arise in an emergency.

Regular testing during this inspection helps to verify that valves, which control the flow of water to the sprinkler heads, are in good working order, free from leaks, and capable of being operated manually if necessary. Relying solely on system activation or conducting tests only at the beginning of each season does not provide adequate assurance of functionality throughout the year, as issues could develop following these infrequent checks. Monthly testing would be excessive and likely impractical for most systems while potentially increasing costs without significant benefits. Thus, annual inspections strike the right balance for effective oversight of fire sprinkler valve functionality within a systematic maintenance approach.
