The Purpose of a 5-Year Internal Fire Sprinkler Inspection

The purpose of the 5-year internal fire sprinkler inspection is to examine your sprinkler piping for potential blockages, including rust, slime, microbiologically influenced corrosion, and other foreign organic or inorganic materials that could prevent water from flowing freely during a fire.

During the inspection, a technician opens the flushing connection at one of the main ends and removes sprinkler heads from a sampling of branch lines. If obstructions are found, a more comprehensive internal investigation is conducted to ensure the system is fully clear and operational.
