How Often Does Anode Rod In A Water Heater Need Replacement


In order for you to prevent your water heater from losing its efficiency, you must know the importance of making sure there are no malfunctions that can lead to deterioration. One of the most essential parts of a water heater is an anode rod. It is designed to protect your water heater’s steal tank from rust and corrosion. But keep in mind that anode roads can wear out because of prolonged use and your water heater becomes unsafe to use. So, how often should you replace anode rods? Continue reading to learn more about anode rod replacements and keep your water heater safe from rust and corrosion. 

What is an Anode Rod?

Usually made from aluminum, magnesium, or zinc, this metal rod is found inside a water heater’s steel tank. It functions like a magnet that attracts corrosive elements in the water that may cause harm to your water heater. However, those corrosive elements, such as sediments and minerals, can cause the anode rod to corrode. Additionally, once it’s completely corroded, the water heater’s steal tank becomes fragile and can lead to leaks and spills.

How Often Should You Replace an Anode Rod?

The longevity of an anode rod depends on water quality, usage, and the material. But generally, an anode rod replacement must be done every three to five years. Check your water heater regularly to determine whether or not your anode rod needs to be replaced. If the rod is corroded or it’s less thick than it originally was, it’s time for you to replace it.

If you’re unsure if your water heater’s anode rod needs replacement, try to call a professional plumber at least once a year for them to inspect. A plumber can check if there are signs of corrosion just by doing a visual inspection. They can also perform other tasks such as flushing the tank to remove sediment build, which can extend the anode rod’s lifespan.

Why is it Important to Replace an Anode Rod?

Since your water heater depends on an anode rod for preventing corrosion, this ensures efficiency and also prolongs the lifespan. Bear in mind that a corroded anode rod also means a corroded steel tank that may lead to many water heater problems. Additionally, the water may have a metallic taste and odor which is unsafe to use.  Therefore, having your anode rod replaced every few years can be cost-effective and could save you from troubles in the long run. Don’t wait until you have to spend high energy bills by overlooking anode rods. Be sure you, or a professional plumber, check it before it’s too late.

Prolong your water heater’s lifespan by replacing the anode rod every three to five years and your steel tank will be protected from rust and corrosion. Although, be sure to check it annually because many factors may affect your anode rod to corrode rather quickly. Contact a professional plumber if you need assistance and start saving money on energy bills before it’s too late. Need help? Contact us at Water Heating Direct to learn more!
