Sprinkler systems protect buildings and save lives — but only if they are properly maintained.
According to NFPA 25, any sprinkler system containing control valves without electronic supervision should be checked on a weekly basis to make sure that they are in the open position.
Additionally, at least four times each year, a full sprinkler system inspection should be performed by a certified technician.
