Anode rod
A sacrificial metal rod inside a tank water heater that corrodes in place of the steel tank. Once it is used up, the tank starts corroding instead.
Should the anode rod be replaced?
On a tank that is otherwise in good shape, replacing a spent anode is a small job that can add life. On a tank that is already rusting or leaking, it is too late; the money belongs in a replacement.
