Water Heater 101: The Role of the Anode Rod

A tank water heater consists of several components working 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. Over time, as this protective layer is slowly eaten away by the corrosive elements, it must be replaced or “recharged” to keep your water heater functioning properly.

How Long Does an Anode Rod Last?

The lifespan of the anode rod depends on several factors, such as water quality and usage. Generally speaking, it will last anywhere from one to five years before needing replacement. As part of proper water heater maintenance, it’s essential to have your unit inspected regularly by a professional plumber to make sure everything is running as it should.

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

Neglecting to replace the anode rod will cause your water heater to suffer from corrosion, leading to poor performance and a shortened lifespan. This could result in expensive repairs or even complete water heater replacement.
