The Role of Anode Rods in Water Heater Maintenance and Repair

Anode rods are a crucial component in the maintenance and repair of water heaters. These rods play a vital role in protecting the tank from corrosion and extending the life of the appliance. Understanding the importance of anode rods can help homeowners ensure their water heater operates efficiently and effectively.

Anode rods are typically made of magnesium, aluminum, or zinc, and are designed to attract corrosive elements in the water that can cause rust and deterioration inside the tank.
