Abstract
An improved anode mounting construction for a water heater. The inner surface of a steel water heater tank is coated with a corrosion resistent material, such as glass, and the tank is provided with an opening which receives an anode rod. The outer end of the anode is secured to a metal cap and the cap is carried by a steel spud which is welded to the outer surface of the tank bordering the opening. The internal diameter of the spud is greater than the diameter of the opening in the tank and a resislent sealing member or gasket is employed to seal the gap between the anode and the annular edge of the tank ordering the opening. The sealing member seals and protects the annular edge against corrosion, as well as protecting the spud, thereby eliminating accelerated consumption of the outer end of the anode adjacent the tank.
