Corrosion and Air Vents: NFPA 13 Code Requirements

This program will address technical changes specific to corrosion and air vents for the 2016 and 2019 editions of NFPA 13. The 2016 NFPA adds a new code requirement that a single air vent is installed for each wet sprinkler system to help reduce potential corrosion activity due to trapped air, and this requirement stays in the 2019 edition.
