Fire Sprinkler Systems: Maintenance Matters

March 29, 2022

Fire sprinkler systems can be an excellent investment for a business but they do require regular inspections and maintenance. After all, the worst time to discover that your system isn’t working properly is during an actual fire.

Sprinkler system maintenance

That’s why we recommend following the National Fire Protection Association’s standard, NFPA 25, which is considered the baseline for inspection, testing, and maintenance of water-based fire protective systems. While frequency varies depending upon the type of system installed, the timeline provided here can be used as a general guide.

For more details, we encourage our policyholders to visit or contact a licensed fire protection company for help.


  • Check the gauges on dry, preaction, and deluge systems. Look for a normal read on air and water pressure.
  • Check control valves for leaks and make sure they are locked, properly sealed, and in the open position. Add proper signage to identify what part of the sprinkler system they control.


  • Check the gauges on wet-pipe systems; ensure that water pressure is maintained and check for physical damage.
  • Perform an external inspection of alarm valves.


  • Ensure that alarm devices are not damaged.
  • Make sure the hydraulic nameplate is secured to the sprinkler riser and is legible.


Have a licensed technician inspect and test your fire sprinkler system components annually, including:

  • Gauges & Control Valves
  • Alarm Devices
  • Hangers/Bracing
  • Pipes and Fittings
  • Sprinkler Heads
  • Anti-freeze Solution
  • Backflow Prevention Components
  • Main Drain & Inspector Flow Tests
  • Water Flow Alarm
