Provided is a system and method for preventing the chemical redox reaction, and thereby, corrosion between potable water and copper piping systems, which causes pinhole leaks in the copper piping systems. A sacrificial anode, made of a material, such as a metal or metal alloy less noble than copper, e.g., iron, zinc, aluminum, magnesium, titanium, and/or alloys thereof, is electrically attached to the potable water copper piping system. Alternatively an active cathodic corrosion prevention system may be used. The active cathodic corrosion protection system is composed of an independent source of DC power, a voltage controller and a non-sacrificial grounding anode. The negative terminal of the voltage controller is connected to the potable water copper piping system. The system is maintained at a voltage and/or potential above the reduction potential of copper. |
