Procedure for Inspecting and Testing Sprinklers

Howdy y’all!

This semester I’m working on a fire suppression class, and later this semester we’re supposed to have a practical exam for the inspection and testing of wet and dry systems.

I know bits and pieces, but if any of you professionals do sprinkler inspections, how do you generally do it? I’ll read NFPA 25 as well, but you know how codes are.
