How Often to Replace water heater Anode Rod? how to replace it

In this informative article let’s know about Anode Rod which is an important part in the hot water heater. In Colorado Springs when Joseph went for maintenance of a heater, he noticed that anode rod was not replaced since 4 years. It was corroded badly that it took high efforts in removing it as its jammed near the threading. So, Inspecting and Understanding how often to replace the water heater Anode Rod should be must as it is the savior of the tank and heating element from hard water corrosions.

Visual Inspection of Anode rod should be done for every 1 year and replacing it should be done between 3 years. These are the general average values, this time depends on the quality of water, type of anode you are using and water heater usage. Let’s learn it below.

What is a Water Heater Anode Rod?

The anode rod is called as a sacrificial rod or savior rod of the water heater. It is one of the important component inside your water heater. Its primary function is to prevent the tank from corroding. Anode rod is made of magnesium, aluminum, or zinc, which has the higher corrosive properties than the steel. Anode rod attracts corrosive elements in the water, sacrificing itself to protect the steel tank.

If you are getting very high levels of hard water Aluminum Rod would be a better choice, and if you are getting water between hard to soft them Magnesium Rod would be a better choice.

Why is the Anode Rod Important?

Without a functioning anode rod, the steel tank of your water heater would quickly corrode, leading to leaks and potentially requiring a complete replacement. The anode rod is designed with metals which are highly corrosive than steel to corrode instead of the steel tank and heater element, By doing so it increases the life of the hot water heater.

How Often Should You Check the Anode Rod?

As the Anode Rod corrodes faster visually checking the anode rod is important to ensure whether it is still performing its protective role. During these checks, you can decide whether the rod needs to be replaced based on its condition. It is recommended to check the anode rod at least once every year.

Signs That Your Anode Rod Needs Replacing

1. Significant Corrosion: If the anode rod is heavily corroded or coated with calcium, it’s time to replace it.
2. Diameter Reduction: If the rod’s diameter is reduced to less than 1/2 inch, it’s no longer effective and should be replaced.
3. Exposed Core: When more than 6 inches of the core steel wire is exposed, the rod has reached the end of its lifespan and needs to be replaced.

Recommended Replacement Frequency

Typically, the anode rod should be replaced every 3 to 5 years, depending on several factors:

1. Water Quality: Hard water with high mineral content can cause the anode rod to corrode faster, necessitating more frequent replacements.
2. Water Usage: Higher water usage means the anode rod will degrade more quickly, requiring more frequent inspections and replacements.
3. Tank Type: Some newer water heaters come with multiple anode rods or powered anode rods, which may have different maintenance requirements.

How to Replace the Anode Rod

Replacing the anode rod is an easy and straightforward process that you can do yourself if you have correct tools and steps:

1. Turn Off the Power and Water: Ensure the water heater is turned off and the water supply is shut off.
2. Drain a Few Gallons of Water: Open the drain valve at the bottom of the tank to drain a few gallons of water, reducing the pressure.
3. Locate and Remove the Anode Rod: The anode rod is typically located at the top of the water heater. Use a socket wrench to unscrew and remove the old rod. If the threads are rusted or jammed apply a very small amount of penetrating oil, make sure it doesn’t get inside the tank.
4. Install the New Anode Rod: Insert the new anode rod into the tank and tighten it securely with a socket wrench. There may be some rubber washers or sealants, if they are worn or damaged replace them too.
5. Restore Power and Water: Turn the water supply back on and restore power to the water heater.

Conclusion

Regularly replacing the anode rod in your water heater is a small but crucial task that can prevent major issues and extend the lifespan of your unit. By checking the anode rod annually and replacing it every 3 to 5 years, you can ensure your water heater remains in optimal condition. Always consider water quality, usage, and tank type when determining the replacement frequency. If you don’t have any idea about Anode Rod, Hire a professional to help you replace the Anode Rod.
