Water Heater Basics: Why Is The Anode Rod So Important?

Several components make up a functional tank water heater. These all work together to heat and store water in your home. As the expert team in water heater repair in Durham, NC, Optimal Plumbing Solutions explains the role of anode rods and how they ensure the longevity and performance of your water heater.

What is the Anode Rod?

The anode rod is composed of a steel core wire covered in aluminum or magnesium. It acts like a magnet for corrosive particles in the water, drawing them away from the tank walls and sacrificing itself in the process.

Think of it like a bodyguard for your water heater. It attracts corrosive minerals in your water. Instead of letting those minerals eat away at your tank’s interior, they attack the rod instead.

Eventually, that rod wears out. But that’s its job. It’s designed to take the damage so your water heater doesn’t have to.

How Long Does an Anode Rod Last?

Water quality and usage are the key determinants of how long an anode rod lasts. Generally speaking, it will last anywhere from one to five years before needing replacement.

As part of proper water heater maintenance, homeowners who want to stay on top of upkeep should have their unit inspected regularly by a professional plumber. Experts can make sure everything, including your anode rod, is running as it should.

What Happens if You Don’t Replace the Anode Rod?

When the anode rod is used up and not replaced, your tank is next in line. Corrosion kicks in, and the clock starts ticking.

First, you’ll notice a drop in efficiency. Then, weird smells. Eventually—leaks, rust-colored water, or total system failure. These could result in expensive repairs or even complete water heater replacement.
