In addition to a heating element, your water heater has several components that prepare the liquid for use and keep equipment operating at maximum performance. The anode rod, for example, works to stop premature tank corrosion and ruptures. To understand why your water heater needs a fully-functioning anode rod and how to tell when it stops working, learn more here.    

Why Water Heaters Have Anode Rods 

Located at the top of a water heater, an anode rod is a steel wire encased in zinc, aluminum, or magnesium. Sediments and minerals in the water attach to the metal instead of the tank lining. This will extend the life of your investment since the substances won’t get a chance to eat away at the tank, causing rust spots to develop. Once the tank starts to leak due to corrosion, it can’t be repaired. 

How to Tell Whether It’s Time for Replacement

While anode rods typically last four to five years, the condition of the water is one factor that affects how long the part will last. Soft water, for example, corrodes the metal faster than hard water since it’s more prone to damaging the interior siding of the tank. Additionally, aluminum models won’t corrode quickly when exposed to hard water, while magnesium anode rods are regularly used in homes with soft water. How much water flows through the appliance also factors into how frequently you’ll need to replace the rod.

When the anode rod needs to be replaced, you might notice faucet and aerator clogs more often. This is a sign the rod can no longer attract sediment, which allows the particles to mix with the liquid and accumulate in plumbing fixtures. If you hear popping sounds coming from the tank, call a plumber immediately for help, as this could be an indication the lining is starting to erode because the rod can no longer do its job.
