How does a sacrificial anode for a water heater work?

The anode has one purpose, which is to sacrifice itself and protect the hot water heater from corrosion. The anode is a piece of alloyed metal attached to the metal surface, in this case the thread of the water heater. When the anode is screwed on, it gives off a protection against corrosion in the hot water heater.

The sacrificial anode is the alloyed metal that will be consumed, which means you won't have a hot water heater that has corroded. Once the sacrificial anode has been used up, it can be replaced quickly and easily, which is a quicker and cheaper solution than replacing the hot water heater.
