Many manufacturers recommend water heater anode replacement every two to four years depending on the hardness of the water that passes through the tank and the quality of the water heater lining.
If your water heater has a 12-year warranty and itâs been in service for 15, it might be time to get a new one. In homes with hard water, which can be tougher on water heaters, a heater may fail within the warranty period. If you haven't replaced your water heater in a few years, you'll find more choicesâand more energy-efficient regulationsâso do your homework.
