ills with air. The readings of an air gauge should be indicated above the water gauge. Inspectors first look at the gauges’ readings to determine whether there are leaks or if the system has gone operating normally. Anything unusual is recorded in the logs.
Every three years an inspection for fire sprinklers is tests where both water chokes, and it is also triggered by the procedure. Following that is a complete testing of flow that mimics an actual fire and evaluates how effective an apparatus works when operating in actual conditions. Inspector tags record information related to the functioning of the system. Next, determine if the system restored properly after an accident. Inspection of the gauges then indicates whether they need replacing or recalibration. They usually need replacement/recalibration five years from the last service/restoration.
Following that, the fire sprinkler inspection checks the heads to be sure they’re working properly. This video demonstrates the necessary amount of heads to replace for every system. Also, you can see marks on various couplings that indicate the dimensions of the system.
