What Happens During a Fire Sprinkler Inspection?

The video goes over exactly what takes place during a fire sprinkler inspection to better prepare people for future evaluations. First, clampers with the water stored below them typically sit in a heated and enclosed room. The rest of the system above fills with air. Lower readings should indicate on the air gauge located above the water gauge.

The first thing inspectors look at are the readings on each valve to tell if there are leaks or if the system’s offline. Records capture anything that’s out of the ordinary.

Every third year, fire sprinkler inspection involves a test where both the water chokes, and the system trips during the process. Next, a full-flow test simulates a fire and times the effectiveness of the apparatus in a real-life scenario. Inspector tags store details pertaining to the system’s operation. Once done, the next test tells whether the system resets properly after an incident to make sure no valve sticks in the closed position. Inspection of the gauges then indicates whether they need replacement or recalibration. They usually need replacement/recalibration five years from the last service/restoration.

Fire sprinkler inspection focuses on the heads next to make sure they’re all in good condition and the individual wrenches for each job. Here the video indicates the number of replacement heads people need for the respective amount different systems have. As a bonus tip, one tells the size of the system via markings on the various couplings.
