Broad Responsibilities

Sprinkler fitters are pipe fitters who work specifically in fire protection.

They inspect and test systems, as well as repair defective, worn or broken parts. They may be tasked to perform National Fire Protection Association inspections on buildings or new installations.

Day-to-Day Tasks

On a daily basis, the fitter selects pipe sizes and materials, measures and marks pipes for cutting and threading, assembles and secures pipes, tubes and fittings, and turns off heating systems to secure new pipes.
