Water heaters are one of the most essential systems in any home, but they often get neglected until something goes wrong. One of the simplest and most important ways to extend the life of your water heater is by replacing the anode rod. This small component plays a big role in protecting your tank from corrosion and costly repairs.
What Does an Anode Rod Do?
Inside every traditional water heater tank is a metal rod known as the anode rod. Its job is to attract corrosive minerals and impurities found in water, preventing them from eating away at the steel walls of the tank. This process, called electrolysis, helps preserve the integrity of the water heater and keeps it running efficiently for years.
Over time, the anode rod naturally wears down as it sacrifices itself to protect the tank. Once it’s completely corroded, the water heater tank becomes vulnerable to rust, leaks, and sediment buildup. Replacing the anode rod before it fails can often double the life of your water heater and save you from an expensive replacement.
How Often Should You Replace the Anode Rod?
Most plumbers recommend inspecting the anode rod every two to three years. Homes with hard water or high mineral content may need more frequent inspections. If the rod is significantly corroded or reduced in size, it’s time for a replacement. Regular water heater maintenance performed by a licensed plumber can help you stay ahead of problems and avoid premature tank failure.
Signs It’s Time to Check Your Anode Rod
- Hot water has a metallic odor or taste
- Rust-colored water from your taps
- Water heater makes popping or rumbling noises
- Tank is more than 5 years old and hasn’t been serviced
Ignoring these warning signs can lead to tank leaks, water damage, and higher energy bills.
