Your water heater allows you to take hot showers, wash dishes, and do laundry with little to no hassle. Just like any other modern appliance, you need to schedule regular inspections for your water heater. While they require very little maintenance, you or a plumber should regularly check the anode rod. If you are unfamiliar with this, the information below will explain what it is, why you need it, and what you should look for during your next inspection.

A Brief Guide to the Water Heater Anode

What Is It?

The anode rod is suspended in the water heater's tank, and it consists of a steel core wire covered in aluminum, zinc, or magnesium. It is designed to attract the corrosive elements in the water and keep them from attaching to the walls of the tank. The anode prevents the water heater tank from corroding, mitigates the need for plumbing service, and extends the life of the appliance.

When Does the Anode Need Replacement?

After installing a new anode, its aluminum, zinc, or alloy coating should start to look "chewed on" after about six weeks in the tank. Over time, it will continue to erode until you can see the steel core wire underneath. Once you can see about six inches of the core wire (usually around five to six years after installation), it's time to replace the anode.

What Factors Affect Anode Life?

The life span of the anode depends on the type of material and the quality of the water. Magnesium rods work best with naturally soft water, while aluminum anodes withstand submersion in hard water with high concentrations of calcium or magnesium carbonate. If you notice a rotten egg smell from the water heater, have a plumber install a zinc rod, which doesn't create the same, smelly compounds during its chemical reactions with the water. If you treat your water with a water softener, the added salt will likely shorten the lifespan of your anode rod. If you begin to notice premature issues with the anode or it is time for it to be replaced, contact a plumbing contractor for a consultation and inspection.
