Abstract
An anode is mounted to the top of a water heater tank which has a spud with external threads welded to the top thereof. The spud extends above insulation which surrounds the water tank and covers the top of the water heater. An anode rod is inserted into the water tank through the spud and has a steel core welded to a flat cylindrical steel disk which extends radially outwardly of a magnesium cylinder formed about the core. A water sealing gasket is positioned between the disk and the annular surface formed by the open end of the spud. A nut fits over the disk and engages the threads on the spud, and clamps the anode to the spud so that the threads are isolated from water in the tank, allowing easy removal of the anode after the passage of time.
