The word corrosion is derived from the Latin word “to gnaw.” And that’s a pretty good description of what corrosion does to metal: it gnaws it away. Corrosion starts when water is in contact with metal in the presence of oxygen, and it’s one of the main enemies of parts of your plumbing system. Even corrosion-resistant copper pipes can suffer from specific types of corrosion.
