Thanks to the anode rod, water heaters are safeguarded from the corrosion that occurs when metal, air, and moisture combine. This rod inside the tank consists of a steel core within a zinc, aluminum, or magnesium exterior. It works by corroding before the tank’s steel interior rusts. At the same time, it releases electrons that help defend the tank. However, this protection doesn’t last forever. To help you avoid the need for water heater repair, here are a few points to know about checking the anode rod.

Why Should You Check the Anode Rod?

The anode rod will not last as long as the water heater tank. Once it’s deteriorated to a certain point, it will no longer protect the tank from corrosion.

The corrosion rate depends on several factors, so inspect it regularly to see if it needs replacement. Without this upkeep, the water heater will have a shorter service life, leaving you with costly repair or replacement needs.

What Are the Signs of Anode Rod Failure?

On average, an anode rod will last about six years. However, since it can deteriorate at a faster rate, you should check it at least once a year. If your water has a rusty appearance, bad odor, or substandard temperature, a faulty anode rod may be to blame. You should also check the part if the tank develops rust or leaks.

To examine the rod, shut off the water supply to the tank and make sure it’s not heated. Once the temperature is safe, remove the rod from the tank. While it’s normal for the part to show signs of wear, it shouldn’t reveal more than six inches of the steel core. If the steel is exposed to this degree, contact a water heater repair specialist for a replacement.

What Contributes to Anode Rod Deterioration?

If you use a softener to correct hard water, your anode rod may deteriorate faster. The presence of sodium in softeners can speed up the rate of corrosion.

Also, magnesium rods work best at preventing corrosion but don’t last as long as their aluminum counterparts—especially when exposed to hard water. If you have hard water, aluminum may be the better choice.
