Most Arlington, TX homeowners have never heard of the anode rod, but it is the part that keeps your water heater from corroding from the inside out. Without it, your tank degrades faster, your hot water quality drops, and you could be looking at a premature water heater replacement. Knowing when to replace this one small component can add years to your system and save you hundreds of dollars.
Here, we put our experience as the leader in trusted water heater repair in Arlington, TX, to work to explain what this important component is, what it does, and how often to replace the anode rod in a water heater for maximum performance.
What Is an Anode Rod and Why Does Your Arlington Water Heater Need One?
Anode rods are metal rods, usually made of aluminum, zinc, or magnesium, that run the length of the water heater’s steel tank. They essentially act as magnets, attracting particles in the water like sediment and hard water minerals, via the process of electrolysis. This prevents the contaminants from accumulating on the sides of the tank lining and causing corrosion, which can lead to leaks and other issues with the water heater.
Anode rods do a great job of protecting your water heater, but over time, the materials they collect build up on the surface, eventually corroding the metal and reducing effectiveness and water heater longevity.
If you are not sure when your anode rod was last replaced, our Arlington water heater team can inspect it during a routine maintenance visit and tell you exactly what condition it is in.
How Often Should You Replace the Anode Rod in Your Water Heater?
Although the average water heater will last up to 15 years with regular maintenance, an anode rod’s life expectancy is significantly shorter. The short answer: most homeowners should replace the anode rod every three to five years.
As a general rule, most plumbers recommend an anode rod replacement frequency of every three to five years. If you have a large family or otherwise have a lot of water flowing through the tank, you might need a new rod more frequently. Hard water, a common issue in Arlington, can also shorten the rod’s lifespan.
Plumbers inspect the component as a standard part of annual water heater maintenance, looking for signs of anode rod wear. You can expect to invest in a new rod if:
- The current rod is over a decade old, regardless of whether it or the tank shows signs of corrosion.
- A visual inspection of the rod shows extensive corrosion.
- The rod is less than half of its original thickness.
- You have discolored water coming from the taps, or the water contains sediment or rust particles.
- Your water has a sulfur (rotten egg) odor, which comes from the rod producing hydrogen sulfide gas.
- The water has a metallic taste or smell.
The purpose of an anode rod is corrosion prevention in water heaters, so seeing some buildup on the rod is normal; it means the part is working as it should. It’s only when deterioration reaches a point where it impedes the rod’s ability to do its job that you need to think about a replacement.
