10 Ways to Maintain Your Fire Sprinkler System

One of the best things you can do in your commercial building is to install a sprinkler system. A properly designed sprinkler system can reduce your exposure to loss of property and lives due to fire.

The same system can also reduce yours property insurance premiums. However, installing a sprinkler system is just the beginning. As a specialized piece of machinery used in production, sprinklers require regular maintenance, repair, and testing to keep them working at their best.

To ensure that your sprinkler system works properly in the event of a fire, the following should be followed:

10 Ways to Maintain Your Fire Sprinkler System

Try All 5 Years

1. Complete an internal pipe test every five years. The purpose of this test is to check the presence of foreign objects that can prevent the flow of water from the pipes to the sprinklers. Follow the entire inspection process Here.

2. Measure or adjust the pressure gauge against the measuring scale. Data that is considered to be inaccurate at the statistical level must be revised or corrected. (See these scales and requirements Here.)

Try Every Year

3. Complete an annual mobility test. This includes testing to ensure that the water flow detection equipment is working, and that the signal is activated properly after allowing the water to flow for 60 seconds. Follow the full test procedure. Here.

4. Inspect the pipes annually to ensure that the system is functional and free from physical damage.

5. Conduct an annual inspection of fire department connections to ensure that helmets are not removed. If the caps are removed, debris or insects can build nests in the joints, causing obstructions in the system for the sprinkler head’s operation.

6. Look for clear sprinkler heads each year. Heads older than 50 years (especially those made before 1920) must be replaced or representative head samples sent to a recognized laboratory for testing. If one head fails the test, all the standing heads must be replaced. Testing is required every ten years.

Try Every Quarter

7. Try the alarm every month. To do this, contact your local fire department or central location and alert them that you will be testing this system. Then activate the alarm through the flow of water through the test valve, and confirm whether the alarm sounds or not.

Try Every Week

8. Visually inspect control valves weekly. This includes making sure that the valves are open and secure, and making sure that there are no leaks in the equipment.

9. Ensure that all receptacles are at least 18 inches below the sprinkler heads to avoid interference with the spray of water from the sprinkler head on the fire.

Watch as often as you want

10. Explain about a complete and comprehensive list of testing and maintenance requirements from NFPA 25 to ensure your system is up to date.


All testing must be performed by qualified personnel, preferably a licensed and insured fire protection contractor. Always keep sprinkler design and test records on site to allow access to contractors, loss insurance agents, and insurance brokerage firms like Verisk.
