When your home’s water heater is running efficiently, you stay comfortable and enjoy lower energy bills. Since your water heater is susceptible to corrosion and rust, homeowners need to schedule regular maintenance to spot any issues early. The anode rod is a key component of this inspection. This guide will break down the function of the anode rod and why it’s a crucial part of your water heater. 

What Is an Anode Rod?

Since water heaters are generally made of materials like steel, they can rust and corrode over time. However, to combat this deterioration, manufacturers equip these systems with an anode rod. This device attracts the elements that would otherwise corrode the tank. In essence, the rod becomes corroded and rusted over time while the tank stays intact. 

How Can You Tell When You Need a New Anode Rod?

The best way to determine whether you need to replace an anode rod is to remove it from the tank and inspect it. The rod may look corroded, or it might have a “chewed up” appearance. There will also likely be signs of rust on the rod as well. If you notice exposed wire under the corroded metal, be sure to replace the rod. This will prevent corrosion and rust from affecting your water heater. 

What Affects Its Life Span?

One main factor that affects the life span of an anode rod is the hardness of the water. If you use a water softener in your heater, the anode rod may corrode more quickly. Be sure to check the rod more often if this is the case. The material that the rod is made of can also have an impact on its life span. Aluminum rods tend to last longer than magnesium, for example. A water heater professional can make recommendations for your specific tank and water system.
