A water heater is essential for completing a variety of day-to-day tasks such as cooking, bathing, and cleaning. However, like any other appliance, it requires regular maintenance for proper and dependable operation. An essential aspect of water heater maintenance is checking the Anode Rod in water heaters and replacing it when necessary.
What is an anode rod, you ask? Read on to learn more about this important component of your water heater, what it does, and how replacing it can extend the life of your water heater.
What is an Anode Rod?
An anode rod, also known as the sacrificial rod, is a long metal rod made of either magnesium, aluminum, or zinc coated around a steel core. It runs down the storage tank’s center and protects the inside of the tank from rust by absorbing corrosive agents from the water. The anode rod is not permanent and will require replacement sooner or later.
How Does an Anode Rod Work?
Over time, the heat, minerals, and other substances inside a water heater’s metal storage tank can cause it to rust and corrode. The anode rod protects the tank from premature corrosion by serving as a negatively charged electrode to attract positively charged ions in water such as magnesium and calcium. Over time, the anode rod begins to rust, thereby “sacrificing” itself to enhance the water heater’s performance and extend its lifespan.
As the anode rod wears down with time, it becomes essential to inspect it regularly and replace it when necessary to preserve the water heater’s integrity. Otherwise, the tank will begin to rust, and corrosion will eat away at the tank walls, leading to leaks, ruptures, and, ultimately, expensive repairs or replacement.
How Long Does an Anode Rod Last?
The average lifespan of an anode rod is between three to five years, depending on the water quality in your home and the material the rod is made of. The best way to maintain your anode rod is to get it inspected annually by a licensed plumber who can advise you on when it’s time to replace it and other important water heater components. Replacing the anode rod before it degrades completely is essential to preventing the corrosive elements from damaging the tank walls.
Signs of Anode Rod Failure
While having a plumber inspect your water heater is the best way to know when the anode rod may need to be replaced, here are some warning signs that indicate it may be going bad:
- Rusty smelling water
- Brown or rust-colored water
- Gel-like substance coming from faucets
- Water heater making popping sounds during operation
- Water failing to reach the present temperature
- Water heater is near or over five years old
