All wet pipe fire sprinkler systems trap oxygen. Oxygen creates corrosion. Corrosion creates leaks and leaks create problems. These aren’t theories or myths. We’ve proven the science and created a solution. Remove the oxygen and you 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.

TRAPPED AIR = LEAKS.
Leaks are no Laughing Matter
