Fire Sprinkler Inspection & Testing

United Fire provides fire sprinkler system inspection and testing services for all types of fire sprinkler systems based on the requirements of NFPA 25 and industry best practices. Periodic sprinkler inspection, testing and maintenance meeting the minimum requirements of the NFPA 25 standard are critically important to ensure water-based fire protection systems work as intended when called upon. These mechanical systems suffer wear and tear issues just as any other building systems and United Fire's standardized processes and procedures will increase the reliability of systems while helping owners to plan maintenance issues to reduce costs as opposed to dealing with more costly repairs that tend to pop up as emergency issues.

When should my Fire Sprinkler System be inspected?

Local fire codes dictate how often your fire sprinkler system should be inspected. Here are some typical sprinkler inspection frequencies based on the NFPA 25:

  • Gauges (dry, pre-action, and deluge systems) – annual inspections
  • Gauges compared to calibrated gauges –  every five years as needed
  • Control valves operated and lubricated – annual inspections
  • Water-flow alarm devices – quarterly inspections
  • Valve supervisory signal devices – quarterly inspections
  • Hydraulic nameplate, General Information signs and Control valve signs checked to ensure they are present and legible – annual inspections
  • Dry pipe systems low point drains – annual inspections
  • Hanger/seismic bracing checked from the floor level for corrosion, and associated problems- annual inspections
  • Pipe and fittings, from the floor level – annual inspections
  • Sprinklers checked for corrosion, leakage, painting and loading to ensure proper operation – annual inspections
  • Spare sprinklers and appropriate wrenches checked so that any sprinklers that are damaged or operated may be immediately replaced – annual inspections
  • Fire department connections – annual inspections
  • Obstruction, internal inspection of piping inspected to check for internal corrosion, obstructive materials and signs of microbiological corrosion ahead of the presence of pinhole leaks – every five years
  • Test water flow and supervisory alarm devices – quarterly inspections
  • Main drain (valve status) tests performed to ensure water supplies are consistent and valve are always open  – annual inspections
  • Antifreeze solutions tested prior to the onset of cold weather – annual inspections
  • Sprinklers tested periodically as required by NFPA 25 to ensure response time index of the sprinklers in service.
