Abstract
Copper tubing in potable water systems is highly resistant to corrosio n. However, pitting attack will occur in tubing carrying cold water wi th an aggressive chemistry (typically, pH of 7.0 to 7.7 and dissolved carbon dioxide of at least 25 mg/L). The most cost-effective method fo r preventing this pitting is altering the water chemistry by raising t he pH and reducing carbon dioxide content.
