One of the most critical home appliances is your water heater. It’s necessary for providing hot water for cooking, cleaning, and bathing, and needs to be in good shape all day and night. The anode rod, in particular, is vital for its performance. Here is a brief guide explaining the importance of this part and how to know it needs replacing.

What Is the Anode Rod?

The anode rod is inside the water heater. It’s a long metal rod usually made of magnesium, aluminum, or zinc around a steel wire. The purpose of this object is to stop rusting in the tank, achieved through electrolysis—a process where the rod’s metal absorbs the ions that cause corrosion inside the tank.

If the anode rod is no longer functioning, it will appear corroded and will be unable to absorb ions, leaving your tank susceptible to rust. Once rust takes over the tank, leaks will soon follow, and you will need to purchase a new water heater.

The best way to check is to schedule an annual water heater maintenance. Plumbers can inspect the anode rod and replace it with a new one if needed. Replacing a rod is simple, but should be left to professionals.

Most anode rods will last about six years, but certain factors may affect their life span. Soft water with high salt content could speed up corrosion. Likewise, hard water will leave behind an excess of scale and mineral deposits that can affect its function. Magnesium rods fare better in soft water and aluminum rods are stronger against the effects of hard water. Zinc anode rods are best for reducing any sulfur or rotten-egg smells that may be emanating from your tank.
