Introduction

Over time, the sacrificial anode rod in your AO Smith water heater plays a crucial role in protecting the tank from corrosion. Made from magnesium or aluminum, this rod attracts corrosive elements in the water, sacrificing itself to extend the life of the tank. However, once the rod is significantly corroded, it can no longer perform its job, leading to potential rust and premature tank failure. This guide will walk you through the process of inspecting, removing, and replacing the sacrificial anode rod in your AO Smith water heater in a cost-effective way to ensure your water heater continues to run efficiently and reliably.
