Can I replace anode rod myself?

You can replace the anode, but it’s not easy. Most tanks are located somewhere without enough headroom to easily remove the old rod or insert a new one. To begin the process, turn off the electricity (or gas) to the heater, shut its water supply, and open a hot-water faucet to relieve pressure inside the appliance.

Are water heater anode rods universal?





In most cases, water heater anode rods are universal. The only exceptions are : Buderus : They use another type of threading to install the magnesium anode. Bradford White : Some model have the anode is built into the hot water outlet.

Is it worth it to replace anode rod?

By replacing your anode rod every 3-5 years, your water heater can last well over 20 years without any risk of leaks and resulting water damage. Unfortunately, if you ignore this important water heater maintenance task, you may need to replace the entire water heater after only 10 years of use.

How often should you replace the anode rod in a water heater?

Most water heater manufacturers will recommend inspecting the condition of the sacrificial anode every one (1) to three (3) years and replacing it when it has been consumed more than 50%. This is especially true if you have hard water or use a water softener.

How do I know which anode rod to buy?

Magnesium anode rods are expected to work better in a home with soft water. Aluminum anodes are appropriate for homes with hard water and a high PH. Zinc anodes work best if a home is starting to smell like rotten eggs and is best for replacing water heaters that already dissolved.

Should you use Teflon tape on anode rod?





Teflon tape is safe to use on anode rods to establish a watertight seal, some manufacturers even recommend it. It should not interfere significantly with the electrical contact between rod and tank.

Is my anode rod aluminum or magnesium?

Table of Differences Between Aluminum and Magnesium Rods

Aluminum Anode Rods Magnesium Anode Rods
Better suited for hard water Better suited for soft water
Has a longer lifespan as it takes longer to corrode Will not last as long as an aluminum rod as corrosion occurs faster

What size socket do I need for an anode rod?

1 1/16-inch

4 Use a ratchet wrench and 1 1/16-inch deep socket to unscrew the anode rod from the heater.

How do you measure an anode rod?



As a rule you want the anode to be “tip to toe” running the full height or length of the tank. If you cant see your brand on the chart then just measure the length of the tank and pick the closest length of anode. If the anode is too long they can be simply cut to length with a hack saw.

How much does it cost to replace an anode rod?

An anode rod costs about $50. Some homeowners may feel comfortable replacing it themselves. If not, call a professional plumber, who can assist. The cost of having it replaced professionally may be around $250 or $300.

Can anode rod causing rotten egg smell?

Many anode rods are made of magnesium or aluminum. When these rods corrode, the metals react with the sulfates in the water, turning the sulfate into stinky hydrogen sulfide.

Is it too late to replace anode rod?



The downside is that if you wait too long to replace the anode rod, it may be too late. If more than five years has passed, it may be too late to save the water heater. Before changing the part, a plumbing professional can drain the water heater to gauge the extent of corrosion inside the tank.

Are anode rods all the same size?

Anode rods vary in length and material. Some anode rods are installed at the top of the water heater tank, while others are attached to the hot water outlet. The diameter of residential water heater anode rods is universal at 3/4 inches. However, the length and type of the anode rod may not be the same.

Can an anode rod be cleaned and reused?

You cannot clean your anode rod in your water heater .
However, it is important to inspect the sacrificial anode rod every 1 to 3 years and replace it after more than 50% of its wear and tear to avoid corrosion of your tank.

Does the length of an anode rod matter?

The length of the anode rod is important in the case of a sacrificial anode. Indeed, as its name suggests, it sacrifices itself to protect your tank from corrosion. As a result, the more magnesium or aluminum there is on the anode, the longer the protection time of your water heater will be.

Can you cut an anode rod to fit?



Yes, you can cut your sacrificial anode rod, whether it is magnesium or aluminum, to replace it. To do this, use a pair of gloves and a saw and cut as you remove the old anode.

Are there different types of anode rods?

Anode rods typically come in three varieties, made up of three different types of metals: magnesium, aluminum, and zinc. The magnesium anode rod is the most common type of anode rod. The magnesium rods are best used in areas with soft water as they corrode easily. The second most common type is the aluminum anode rod.

How long will water heater last without anode rod?

The longevity of water heaters without anode rods is about: 5-8 years. The actual lifespan depends on water hardness, water heater type and quality, when the anode rod was removed, and how hot the water is. In extreme cases, the water heater may only last 3-5 years without an anode rod.
