To perform a long term pressure test including the boiler, ALL trapped air must first be removed from the boiler. A loss of pressure during such a test, with no visible water leakage, is an indication that the boiler contained trapped air. K. OxYGEN CORROSION : Oxygen contamination of the boiler water will cause corrosion of the iron and steel boiler components, which can lead to failure. As such, any system must be designed to prevent oxygen absorption in the first place or prevent i
