If you have a hot water tank at home, you may need to be made aware of the role of anode rods in its service. Anode rods are metal rods that safeguard the tank from corrosion and prolong its lifespan. Plumbing and HVAC companies pay special attention to making sure the anode rods are well-installed in hot water tanks to ensure maximum efficiency.
In this blog post, you will learn what anode rods are, how they work, why they are important, and how to maintain them.
What Are Anode Rods?
Anode rods are long, cylindrical metal rods. They are inserted into the top of the hot water tank. Typically, anode rods are made of magnesium, aluminum, zinc, or a combination of these metals.
Anode rods act as sacrificial metals that corrode faster than the steel tank. This means that they attract the corrosive elements in the water and prevent them from attacking the tank. As a result, the tank lasts longer and performs better.
Working Of Anode Rods
Anode rods work by a process called electrochemical corrosion. This is when an electrolyte, such as water, connects two different metals. The metal that is more reactive or has a higher potential becomes the anode and gives up electrons to the less reactive metal, which becomes the cathode.
The anode corrodes, and the cathode is protected. In a hot water tank, the anode rod is the anode, and the steel tank is the cathode. The water acts as the electrolyte and facilitates the flow of electrons.
Importance Of Anode Rods
Anode rods are important because they extend the life of your hot water tank and save you money in the long run. Without anode rods, the steel tank would corrode faster and leak or burst.
This would cause water damage, loss of hot water, and high repair or replacement costs. According to some estimates, anode rods can double or triple the life of your hot water tank.
Anode rods are also important because they improve the quality of your hot water. Corrosion can cause rust and sediment to build up in the tank and contaminate the water.
This can affect the taste, smell, and colour of the water, as well as its safety and health. Anode rods prevent this by reducing the corrosion and keeping the water clean and clear.

How To Maintain Anode Rods?
Anode rods are not meant to last forever. They will eventually wear out and need to be replaced. The lifespan of an anode rod depends on several factors, such as the type and quality of the rod, the water hardness and acidity, the water temperature and pressure, and the frequency and duration of use.
Generally, you should examine anode rods every year and replace them every 3 to 5 years.
To check the condition of your anode rod, you will need to turn off the power and water supply to the tank, drain some water from the tank, and unscrew the anode rod from the top of the tank.
You can use a wrench or a socket to do this. Then, inspect the rod for signs of corrosion, such as pitting, flaking, or thinning. If the rod is less than half an inch thick or if it is coated with calcium carbonate, it is time to replace it.
To replace your anode rod, you will need to buy a new one that matches the size and type of your old one. You can find hot water tanks and anode rods from a professional HVAC company. It is recommended that you hire a professional plumbing service to handle the installation, repair, or replacement of anode rods and overall hot water tanks.
