What is the Anode Rod?

At A.M. Plumbing & Rooter, we realize most homeowners probably do not instantly think to call a plumber in Corona, CA, just to explain how each part of their plumbing works. However, if you have a tank-based water heater, it’s advisable to know a few things about an important part of your water heater.

Here’s what you need to know about the anode rod

Protecting Your Tank

Every tank-based hot water heater has an anode rod. It’s a temporary rod with a steel core covered by a coating of magnesium, aluminum, or zinc. The main function of this rod is to protect your tank’s metal lining from rust and corrosion.

Extending the Water Heater’s Lifespan

The anode rod minimizes the need for water heater repair in Corona, CA, by essentially acting as a magnet. It draws minerals away from other parts of the tank to help it stay strong and stable for a longer period of time.

If you have soft water, a magnesium-coated rod is usually what’s recommended. An aluminum-coated rod may be inserted into your tank if you have “hard” or high-pH water. Zinc anode rods can be helpful if you have issues with water odor. Consult our team for more information when you need our expertise on water heater services.

Checking and Replacing the Anode Rod

Your anode rod will already be in place after a new water heater installation. It still needs to be checked on a regular basis, though. The lifespan of an anode rod can vary, but it’s generally advised to have it checked every 2-5 years. Ideally, it’s best to have the rod replaced before it has fully dissolved.
