What is an anode rod and why is it important?
Anode rods or “sacrificial rods” are metal rods that are placed inside your hot water tank, attracting corrosive materials to prevent those materials from sticking to the walls of the tank and causing damage. These anode rods corrode over time and need then to be replaced. Anode rods can be made of different materials, each of which is better or worse at doing certain things.
Aluminum rods are the best if you have hard water and magnesium rods are better for soft water. Anode rods with zinc can be use to eliminate foul odors and have antifungal properties. Most anode rods will fit any tank, but some tanks are shorter and the rods need to be cut to fit.
How often should you replace the anode rod?
Typically you should change the anode rod in your water heater once every five years, however, if you’re using a water softener, it can erode in just six months. Other factors like your water composition and the material of your anode rod can effect how long the anode rod lasts. You should normally check your anode rod yearly to see if it’s still intact or check it every six months if you use a water softener. Since you should be cleaning out the water heater tank at least once a year anyway, this is a great time to check the anode rod. There are also some signs that you should change your anode rod, like rotten egg smells or loud noises from the water heater. Call Service Pros Plumbing today and we can schedule someone to come out and change your anode rode for you.
