Description
An anode rod is a rod made of "sacrificial" metal. Like batteries, the anode produces an electrochemical reaction in the tank. The anode slowly wears away instead of the lining of the tank. As long as the anode is present and functional, almost all corrosion or rusting on the tank's lining is prevented.
Access
To all consumers who are shopping for a new water heater, an important aspect of the new appliance is the accessibility to its anode rod.

Anode Evaluation
If the anode rod has more sacrificial metal than exposed steel rod, then it is still in good shape. However, if the entire surface becomes covered in calcium carbonate and this calcium carbonate becomes hard, this will prevent the anode from protecting the tank any longer. This is known as passivation. If the anode has passivated, it will not look so by sight alone.
