Abstract
A combination anode mount and hot water outlet for a water heater. The water heater includes a steel tank to contain water to be heated and has an upper head formed with an opening therein. An annular internally threaded spud is secured to the upper surface of the head with the axis of the spud being located eccentrically with respect to the axis of the head opening. An elongated body or support formed of an electrically insulating material, such as plastic, extends through the opening in the head and a cam shaped flange extends laterally from the upper end of the body and is disposed within the spud and is supported on the upper surface of the head. The body is formed with an outlet passage which communicates with the interior of the tank so that heated water in the tank can flow through the passage for discharge. An anode is secured to the lower end of the body and an electrical connector embedded in the body is connected to the anode and extends upwardly and is exposed at the cam flange. By rotating the body within the opening in the head, the cam will wedge against the threads of the spud to lock the body against rotation and provide a positive electrical connection between the electrical connector and the spud.
