What is a Water Heater Anode Rod?

When it comes to water heater maintenance, the role of the anode rod cannot be overstated. In fact, it is one of the most critical components in protecting the tank from corrosion and extending the lifespan of the water heater.

The anode rod is a long metal rod usually made of magnesium or aluminum that is inserted into the water heater tank. The rod is designed to attract and collect corrosive particles in the water that would otherwise eat away at the tank walls. As the rod collects the corrosion, it deteriorates over time, sacrificing itself to protect the tank.

Without an anode rod, the corrosive particles in the water will attack the tank walls, causing rust and leaks that could eventually result in a catastrophic failure of the entire system. By attracting and neutralizing these particles, the anode rod acts as the first line of defense in protecting the water heater from corrosion.

It’s important to note that the anode rod is not a permanent fixture and will need to be inspected, and eventually replaced, to ensure its effectiveness in protecting the tank from corrosion.
