Changing the anode rod every four years is a great way to extend the life of your water heater. The anode rod is a special metal component that’s meant to slowly dissolve so that the tank itself doesn’t corrode. When the anode rod is depleted, it no longer offers corrosion protection for the tank. To avoid tank damage, it’s best to replace the rod before that happens.
We offer anodes made from magnesium and aluminum, available in various lengths. Aluminum rods are available where sulfur odor or “rotten eggs smell” is a problem. Flexible rods are available where overhead space is tight for installation.
This video shows detailed step-by-step procedure for how to replace an anode rod on a gas or electric hot water heater.
