Fire sprinkler inspections are an essential part of the life of a sprinkler system. 
 

They happen weekly, monthly, quarterly, annually, 3-years, and 5-years.  Each inspection has its own purpose, but the same overall goals:  1) extend the life of a sprinkler system; and 2) ensure the system is going to work if a fire ignites.

In this post, we're going to dive into what to expect at an annual inspection.

Inspection schedules are determined by NFPA 25.  For a full review of all inspection needs from weekly to 5-year inspections, you can find that information at the NFPA link.

​
