Fire sprinkler systems are often the first line of defense in the event of a fire—but only if they are working properly. To ensure that fire sprinkler systems are functional and up to code, it’s crucial that you follow regular testing, inspection, and maintenance schedule. What should that schedule be? Here’s how often fire sprinkler systems should be tested, inspected, and maintained.

How often should you have your fire sprinkler system tested?

There isn’t just one simple answer like “once per year” for when you need to test your fire sprinkler system. There are many different components to a fire sprinkler system, each with its own testing schedule. According to the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, NFPA 25, physical testing must be done:

Fire Sprinkler Component

Testing Schedule

Sprinkler mechanical devicesQuarterly
Vane and pressure switch devicesSemiannually
Complete fire sprinkler system test, including low flow tests, alarm tests, trip tests, deluge, preaction valves, antifreeze concentration tests, and fire pump testsAnnually
Sprinklers exposed to extra-high temps and harsh environments (Test or Replace)Every 5 years
Gauges (Test or Replace)Every 5 years
Dry sprinklers (Test or Replace)Every 10 years
Fast-response sprinklers (Test or Replace)20 years initially, then every 10 years
Standard response sprinklers (Test or Replace)50 years initially, then every 10 years

How often should you have your fire sprinkler system inspected?

Per NFPA, the inspection schedule for fire sprinkler systems is as follows:

Fire Sprinkler Component

Testing Schedule

Gauges (dry, pre-action, and deluge systems)Weekly
Gauges (wet pipe systems)Quarterly
Waterflow alarm devices, supervisory signal devices, hydraulic nameplates, valves supervisory alarm devices, and control valvesQuarterly
Pipes and fittings, hanger/seismic bracing, spare sprinklers, and information signageAnnually
Internal inspection of sprinkler pipingEvery 5 years

How often should you have your fire sprinkler system serviced?

If you keep up on the testing and inspection schedule, maintenance is easy. Any time a component fails inspection or testing, it’s time to repair or replace it. Additionally, if components are showing signs of rust, corrosion, or wear, you can note that during your testing and inspection process and replace them. A reputable testing and inspection company will know NFPA 25 and be able to perform all necessary maintenance on the required schedule to ensure compliance.
