The Role of the Anode Rod

January 16, 2024

One reason to call a plumber in Nokomis, FL, from Bullseye Home Services is to have your anode rod checked, particularly if you have a water heater with a tank. If you’re not fully aware of this important part of a conventional water heater, take a moment to learn more about the role of the anode rod.

What is an Anode Rod?
You won’t find an anode rod in a tankless water heater. It’s a temporary rod with a steel core that’s only used and needed in a conventional water heater. Coated with zinc, aluminum, or magnesium, it’s a rod that’s directly inside of the tank to help protect the tank’s inside lining.

How Does It Work?
With a tank-based water heater installation, the anode rod will be in place already. It works by drawing corrosive minerals away from the metal tank walls. So, the role of the anode rod is primarily to extend the life of your water heater by minimizing rust formation and corrosion.

How Long Will an Anode Rod Last?
The quality of your home’s water and how often use your water heater are among the factors that will determine how long an anode rod lasts. Typically, however, these rods last about 3-5 years. Failure to have your anode rod checked can result in the premature need for a water heater replacement. We recommend being proactive about water heater maintenance and having the rod checked every 2 to 5 years.
