The sacrificial anode is designed to attract minerals and impurities in the water which would otherwise react with the inside of the tank and cause it to rust and deteriorate. This ‘sacrificial’ rod slowly rusts and degrades, sacrificing its own life for the greater good of your hot water tank.
In most cases (and depending on the properties of the water where you live) sacrificial anodes need to be replaced once every five years. Failure to replace a sacrificial anode is probably the biggest single cause of hot water tank failure. If you’re careful and replace your sacrificial anode regularly, you can easily extend the service life of your hot water tank by another five years, ten years or even more.
