How often should you replace the anode rod in your water heater? Not replacing it can lead to serious consequences.

Many households have used water heaters for years without knowing about a critical component called the magnesium rod. Let Master Xiaoyijiang explain: **Function of the Magnesium Rod:** Technically known as a sacrificial anode, the magnesium rod protects the water heater tank from limescale buildup and electrochemical corrosion by corroding first. Simply put, it takes the hit to save the tank. **Replacement Schedule:** - Hard water areas: Replace every 1 year(s) - Moderate water areas: Replace every 1.5-2 year(s) - Soft water areas: Replace every 2-3 year(s) - Reduce interval if usage is frequent **Consequences of Delayed Replacement:** 1. Tank corrosion begins once the magnesium rod is fully consumed 2. Tank perforation leads to leaks and total unit failure 3. Severe scaling on heating elements increases power consumption 4. Elevated heavy metal levels in water pose health risks 5. In severe cases, electric shock hazards may occur **Estimated Replacement Cost:** - Parts: approx. 30-80 yuan - Labor: approx. 50-100 yuan - We can also clean the tank during service Master Xiaoyijiang recommends cleaning the tank whenever you replace the magnesium rod—two benefits in one.
