A water heater has many internal components that keep it running, but the anode rod is the system’s most significant line of defense. Without it, your heater would be vulnerable to premature wear and tear. Here’s what you need to know about this essential component, including how to maintain its efficiency and when to schedule water heater repairs.

How It Works

Also known as a sacrificial anode, this rod protects the water heater from deterioration. Usually made of a softer metal like magnesium or aluminum, the rod corrodes more easily when it comes into contact with the heater’s high temperatures and water’s natural acidity.

The rod also causes a chemical reaction called electrolysis inside your tank. It attracts the ions that would normally rust the appliance’s steel lining. By performing these duties, the rod sustains the damage that the tank would typically face. 

Potential Problems

Anode rods usually disintegrate after three to five years. After this time, the rod is prone to breaking off and bouncing around the bottom of the water heater. This can crack the glass lining and cause leaks and water damage, leading to costly water heater repairs or an entire replacement.

A depleted rod also leaves the heater vulnerable to rapid corrosion, which can create rusty-looking water. When the component deteriorates, it will look brownish-red with a rough texture. It might also be covered in a white substance, which is calcium that was drawn from the water.

Maintenance Tips 

It’s recommended to have a technician conduct yearly inspections of the water heater. They’ll check the quality of the rod by shutting off the appliance and pressure relief valve.

The plumbing professional will also drain the water to check for signs of rust and calcium deposits. When these leftover sediments buildup, they can corrode and overheat the tank. 

Make sure you know the signs of a depleted rod. If the water is red or tastes like metal, call a professional to inspect the component. Avoid using or drinking contaminated water, as it can cause a variety of issues, such as acne and brittle hair.
