What is the Anode Rod?An anode rod is a long metal rod formed around a steel wire, which is inserted into the storage tank of the water heater. The rod is usually formed of magnesium, aluminum, or zinc. While in contact with the water in the tank, the anode rod will start to degrade over time. This will attract the ions in the water that normally cause rust, a process called electrolysis. As long as the anode rod is in the tank, and degrading, it will prevent the lining of the tank from rusting. This protection does not last forever, however.
MaintenanceSooner or later, the anode rod will degrade to the point where it needs to be replaced. If it is not, the protection over the tank lining will expire and it will start to rust. It normally takes a little over a year for the anode rod to degrade to the point where it is no longer useful. That’s part of the reason it’s so important to schedule a maintenance appointment for your water heater at least once a year.
