Why Replace Your Anode Rod?
Anode rods are a critical maintenance component in any water heater. Over time, the magnesium material is consumed as it sacrificially protects the steel tank lining from rust and corrosion. Replacing a depleted anode rod on schedule is one of the most cost-effective ways to extend the service life of a commercial or residential water heater.
