All wet pipe fire sprinkler systems trap oxygen. Trapped oxygen causes corrosion. Corrosion creates pinhole leaks and leaks cause expensive problems. This science has been tested and proven, and the solution is very simple - remove the oxygen to eliminate the problem. Our products and processes provide simple, permanent solutions by eliminating corrosive oxygen from wet pipe systems. The 2016 edition of NFPA 13 further reinforces the importance of trapped air removal in wet pipe fire sprinkler systems.
