Quick Answer: How To Remove Anode Rod From Water Heater

Should you remove the anode rod in water heater?

Some water heaters have two anodes. Not only is it important to put an aluminum/zinc anode into the heater; it’s also important to remove all previous anodes or the hot water will still smell.

Is it OK to remove anode rod?

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.

How long will water heater last without anode rod?

Diminished Water Heater Lifespan: Without a sacrificial anode rod replacement, the average tank water heater will last a maximum of 8-12 years. However, your water heater may start failing as early as 5 years old without this essential care.

What size socket do you need to remove an anode rod?

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

Do hot water heaters come with anode rods?

Most anode rods are sacrificial, meaning they are designed to corrode (instead of your water heater lining). Because they are meant to break down, they wear out every few years and need to be replaced. Tankless water heaters don’t have anode rods, but all standard tank-style water heaters do.

Are 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. All other water heater brands use a regular magnesium anode with 3/4 ” NPT threads.

Is it too late to replace anode rod?

Anode rods are relatively cheap, usually costing between $30 and $40, and a plumbing pro can install them safely and quickly. 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.

Do glass lined water heaters have anode rods?

Anode Rod. Built into all A. O. Smith glass-lined tank water heaters will be an anode rod to protect the tank and extend its life. The anode rod produces a low resistance electrical current to establish an electrical circuit in the water heater that controls corrosion through cathodic protection.

How do you check the anode rod on a water heater?

Open the spigot and drain a little water to relieve some pressure and heat inside the tank before opening the top for the anode rod. Next, go to the top of your water heater and look for a hex head bolt. If you don’t see the hex head, it’s likely built into your water heater system.

Can a water heater last 20 years?

Tank water heaters will last an average of 8 to 12 years, while tankless water heaters can last even longer, up to 20 years. There are also electric and gas water heaters that will vary in lifespan, but in general gas ones last 8-12 years, while an electric heater could last upwards of 10-15 years.

How do you test a water heater anode rod?

Steps to Tell Anode Rod is Bad Shut off the electricity/gas to your water heater. Grab a bucket and a hose and then attach the hose to the drain valve near the bottom and empty out a few gallons of hot water. If there is rust or sediment, you may want to consider flushing or draining the tank.

Should you use Teflon tape on anode rod?

Yes, teflon tape may reduce the effectiveness of the anode rode by electrically insulating the rod from the water heater chassis. The chances of it completely isolating it are nearly impossible though. Use pipe joint compound if you have it, and use teflon tape if you don’t.

What size is the head on an anode rod?

They are usually around 33 inches long with a ¾ inch diameter. Aluminum anode rods are also about 33 inches long with a ¾ inch diameter.

Can I use impact driver to remove anode rod?

To loosen the rod, you’ll need an air compressor, a 1/2-in. -drive impact wrench and a 1-1/16-in. If you don’t have an impact wrench, go buy a cheap one for about $30. Even with a breaker bar, it can be nearly impossible to break the anode rod free.

How do I know if my hot water heater anode is bad?

A bad anode rod can cause discolored water, a rotten egg smell, air in the lines and intermittent hot water. The anode rod protects the tank of electric water heaters & signs it should be replaced are a rotten egg smell, no heat & strange sounds.

How do you know if anode rod is magnesium or aluminum?

A magnesium rod will generally last less than an aluminum rod. One issue with aluminium rods is that the corrosive material that is formed on the anode tends to harden and sink to the bottom of the water tank.

How do I know what size anode rod to buy?

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 often should anode rod be replaced?

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.

Do Bradford White water heaters have anode rods?

The anode rod in your Bradford White water heater is located at the hot water outlet of your tank. Unfortunately, it is not easily accessible. You must remove the hot water outlet to access it.
