Question: How To Change The Anode Rod In Water Heater?

How often should you change 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 if my anode rod is bad?

Smelly or discolored hot water is the biggest sign that something is wrong with your anode rod. When your anode rod has completely corroded, it can no longer protect your hot water heater lining. Your anode rod will go bad every five years or so.

How do you know when to replace an anode rod?

Schedule professional inspection of the burner, temperature/pressure release valve, venting system, and other system components at least once a year. Inspect the anode rod every year; replace the anode rod every 3-5 years.

Can you remove the anode rod from water heater?

We’ve heard of plumbers or handymen advising people to remove the sacrificial anodes from their water heaters as a solution to smelly water. It’s a solution all right, but one that will ensure your water heater rusts out in record time. There is a reason why removing an anode voids the warranty.

How much does it cost to replace an anode rod?

Most tanks come with one anode, which, in most waters will last four years before needing replacement. Say you do charge $100 to replace the rod. A plumber may charge $200 to $300 depending on the location of the anode and difficulty of the removal.

Which is better aluminum or magnesium anode rod?

For harder water an aluminum anode rod is the best choice for your heater and if you live in an area with soft water then a magnesium anode rod is your best choice. Aluminum anodes tend to be cheaper than magnesium anode rods. A magnesium rod will generally last less than an aluminum rod.

What happens if you don’t change your anode rod?

Since the lining eventually cracks, tanks have a second line of defense against rust: a long metal “anode rod” that attracts corrosive elements in the water. When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement.

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.

Is it too late to replace anode rod?

Anode rods are made of either magnesium or an aluminum-zinc alloy. 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.

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. Bradford White: Some model have the anode is built into the hot water outlet.

Why does my hot water smell like rotten eggs?

You are most likely on well water, and there is a bacteria, known as SRB (sulfate-reducing bacteria), that gets into water heaters and, although harmless to humans from a pure health perspective, creates the odor by digesting naturally occurring sulfur-based elements in the water, releasing tiny amounts of hydrogen

Are powered anode rods worth it?

As mentioned, powered anode rods are well worth the cost, but may not be ideal in every situation. Additionally, you may not wish to replace a rod which is still good just to gain the benefits of a powered one.

Will a bad anode rod make water 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.
