What Does an Anode Rod Do?

Everything You Need to Know About Anode Rods

Anode rods are essential components in water heaters that guard against rust and corrosion, ensuring the appliance runs safely and reliably. If you’ve ever suspected there must be something more to properly maintaining your hot water tank than simply regular flushing, then you’re right – the anode rod is key! This blog will discuss everything you need to know about anode rods. Keep reading to learn more.

What is an Anode Rod?

An anode rod is a metal shaft (usually magnesium or aluminum) inserted in your water heater’s water tank. Its purpose is to protect the inside of the unit from corrosion by attracting elements like chlorine and sulfate, which would otherwise cause damage. Anode rods are shaped like a letter “U” and are usually made of two pieces connected at the center. Anodes perform their job well when properly installed and maintained, providing vital corrosion protection for your hot water tank.

How Long Does an Anode Rod Last?

Anode rods are essential for maintaining a hot water tank in peak condition, but they won’t last forever – depending on usage, they need to be replaced every 3-5 years. If you neglect to replace a worn-out anode rod, it won’t just cause damage to your hot water tank – it can also lead to costly repairs down the line.

How to Replace an Anode Rod

When it comes time to replace a worn-out anode rod, there are two main options: purchase a new one or have a professional install one for you. If you decide to buy a new anode rod, it’s important to note that the size and type must match your hot water tank. Many home improvement stores sell anode rods, but if you need clarification on what size or type you need, a licensed plumber can help.

When replacing an old anode rod, it’s also important to check for any sediment buildup in the bottom of the tank before reinstalling the new rod. This buildup can cause corrosion and damage to your water heater if not removed. Once the sediment is cleared, you can properly install and secure the new anode rod.
