We can answer your questions when it comes to water heater repair and maintenance. For example, if you’ve ever wondered how the anode rod in your standard water heater works, we’re here to help. Let’s dive into the basics of water heater anode rods and go through a brief breakdown of how they work.
An anode rod, sometimes referred to as the sacrificial rod, is a crucial component found in most water heaters. Its sole purpose is to protect the water heater tank from corrosion, making sure it lasts as long as possible. Made from a combination of metals like aluminum, magnesium, or zinc, the anode rod attracts corrosive elements, drawing them away from the tank.
As water flows into your water heater tank, it tends to carry various minerals and impurities that can lead to corrosion over time. This is where the anode rod comes into play. By design, anode rods are more "sacrificial" or reactive than the metal tank itself. They act as a magnet, attracting corrosive elements like sediments, rust, and other minerals.
Once the anode rod attracts these corrosive elements, it undergoes a chemical reaction to protect the tank. The rod itself corrodes instead of the tank, sacrificing its own integrity to save the structural integrity of the water heater. In essence, the anode rod is the unsung hero that takes the hit so that your water heater remains corrosion-free.
Over time, the rod wears out and becomes less effective. When this happens, the tank becomes more susceptible to corrosion, potentially leading to water damage and costly repairs. Fortunately, there are signs to look out for that indicate the need for an anode rod replacement. These include a metallic taste in your water, rusty water, strange odors, and visible signs of corrosion on the tank.
To make sure your water heater remains protected, you should keep up with regular maintenance and check out the health of your anode rod. Try to inspect it every 2-3 years and replace it when it’s corroded, approximately 75% or more. If you aren’t sure how to check for corrosion, we can help. We’re experienced in the repair and installation of many different types of water heaters, including electric, standard, and more. We can easily assess the issue and replace your anode rod.
