Some experts caution against using copper or lead-coated copper in contact with red cedar or redwood or rainwater that drains over the wood. Over time, the copper surface will be etched by the acidic wood runoff. Although failures of cop173per flashings are rare, they have been reported in areas of the Northeast after 10 to 20 years of service.

The negatively charged electrons create a higher voltage to flow from the anode rod to the steel tank causing the anode rod to corrode instead of the steel water heater tank, or other exposed metals such as electric elements. The anode rod is quotself-sacrificingquot and will continue to corrode until eventually it.
