If we asked you to name the most important appliance in your home, what would it be? We’d argue to say that it’s your water heater. After all, your water heater is one of the only systems in your home that gets used every single day—it works hard to provide you with the hot water you need to shower, wash dishes, do the laundry, and more. And if you’re using a storage tank water heater, there is one component, in particular, that is integral in allowing this to all happen seamlessly—the anode rod.
This isn’t exactly a household name, but the anode rod is very important in all households with a storage tank water heater. It provides an essential function in protecting your tank water heater from harm. The anode rod doesn’t last the lifetime of the water heater, though, so it’s important you know the condition of yours.
