How Does an Anode Rod Save Your Water Heater?

What Are Anode Rods, and How Often Should They Be Replaced?

Your water heater has a hidden hero: the anode rod. This metal rod, typically made of magnesium or aluminum, protects the tank from rust by corroding in its place. Without it, your water heater tank could fail in just a few years.

Why Anode Rods Matter

Water contains minerals and oxygen that cause steel to rust. The anode rod sacrifices itself to prevent this, extending the life of your water heater. Think of it as the MVP of your water heater’s defense system!

Signs It’s Time to Replace

1. Foul smells: A decaying rod can cause a rotten egg odor.
2. Rusty water: Indicates the rod isn’t protecting the tank.
3. Corroded rod: If it’s heavily worn or exposing steel wire, it’s time for a new one.

How Often Should You Replace It?

Replace your anode rod every 3-5 years, or sooner if:

• You have hard water (common in Burnet, TX).
• Your water heater works overtime due to high usage.

Replacement Tips

A professional can quickly inspect and replace your anode rod during routine maintenance. If you DIY:

1. Turn off power and water.
2. Drain a few gallons from the tank.
3. Unscrew and replace the old rod.

Why It’s Worth It

Replacing an anode rod is far cheaper than replacing your entire water heater. A little maintenance goes a long way in ensuring reliable hot water and a longer-lasting system.

By keeping your anode rod in check, you’re protecting your water heater—and your wallet—for years to come.
