Corrosion in metal pipes occurs spontaneously by the presence of oxygen in water (there is highly concentration of oxygen in demineralized water). Pipe corrosion is accelerated by corrosive water, low (acidic) pH, low alkalinity, and high concentrations of chloride and sulfate ions. Iron metal pipes corrode the most, followed by zinc (galvanized iron) metal pipes. Modern plastic pipes used in home construction do not corrode.

Oxidation or rust and Galvanic or electrolysis.
