What Causes an Anode Rod to be Replaced?

No one wants to deal with the damaged water tank. The leaky anode rods sometimes put us in such a disastrous situation.

Despite the watery mess, it would be great if you could know why you should replace it.

Yes, so here we are, covering the simple reasons which cause an anode rod to be replaced. Look below-

Reason 1: Increase the Longevity

The anode rods are needed to protect your water tank from the corrosion of harmful bacteria. If your anode isn’t in the best position, your water will not be.

Therefore, replacing the anode faster would definitely increase the lifespan and longevity of your water tank. Changing it at the right time shows your maintenance and care towards it. Don’t delay that, buddy.

Reason 2: Avoid Water Leakage

One of the prominent reasons for water leaking is the damaged water. Therefore, changing the anode rod beforehand is a good idea.

Reason 3: Noisy Water Tank

Sometimes, you may find bangling noises and sounds popping from the tank. It seems very weird. But this is the case for many tanks out there.

Do you know what that is? It signals water corrosion. If you, too, hear such noises, take instant action, dude.

Reason 4: No Replacement in Few Years

Using an anode rod for more than 3 years is not a better practice. Though it may have a manufacturer’s warranty more than that, you could replace it before. It can also avail you of the offer.

Reason 5: Smelly or Discolored Water

This is the most common factor that helps us to identify the damaged anode rod. The smelly, dirty water, along with discoloring, can be very apparent in these cases.

Therefore, for that, we suggest replacing the anode rod as fast as you can before some significant danger strikes in.

How to Remove Anode Rod that has Fallen Into Tank?

Ever lost an anode rod in the tank while replacing it? Ohh yes!! It is a common scenario. And terribly disturbing we bet.

But sure we do have some exclusive ways to fix this problem. Follow us to the quick methods.

Method 1- Use a Magnet:

It can be a promising method for anode rods that are made with metallic or magnetic materials. As most rods have steel in their core it is easier to attract them with a magnet.

Often the amount of iron components in the steel is sufficient enough to be attracted. So, simply holding a magnet can crack the jigsaw puzzle of this problem.

However, this method is not 100% perfect. It, too, has some limitations that should be addressed in order to know it better.

One of the prominent problems is their material. The majority of the common coatings of rods are made of aluminum or zinc which cannot be properly magnetized. As a result, plan A totally fails if your rod falls in this category.

Method 2- Pull it with Hooks:

It’s no big deal if your plan A fails! It’s time to move on to some creative ideas to hook your broken rod from the endless water tank.

Here you have to think your rod is no less than a fish. Use a fishing line and attach a hook at the end of it. Then what? Pop it in the water tank and wait till the rod seeps into it.

It’s unlikely that you will succeed on the first try. After several attempts and sweats, you may be able to securely hook your anode rod. Yeah, it’s surely going to cost you some hell of patience.

Finally when you have caught your fish pull the line upwards and yank your anode rod out of it. And bingo! We got it!

Method 3- Flush the Rod:

You can also get rid of the broken anode rod by simply flushing it out of your water heater. We know, we know, this may seem a bizarre idea but the interesting thing is it works. And, you should definitely know why.

Naturally, water tanks are flushed out at regular intervals. And removing your broken anode rods in this process can be a win-win case.

How weirder it may look, this one is the most viable option out there. As anode rods are prone to decomposition they start to break into small pieces and turn into sediments. Flushing them out will do no harm buddy.

Still, you should know how to flush properly before doing this trick. Some major mistakes like using harsh chemicals or not acknowledging manufacturers’ guidelines can be seriously devastating for your water heater. Ignore these and you’re all set.

Does a Water Heater Operate Without an Anode Rod?

We found this question pretty interesting. The answer is yes, a water heater can operate without an anode rod but not so long and not so secure. We guess you did not get it. Well, we will explain, buddy. 

When the water heater will have no anode rod, it will face corrosion and rust. Gradually, there will be cracks and leakages, which will lead to the tank bursting. The water will have a yellowish appearance due to rust.

There can be some unusual sounds inside the heater and it may continue producing the noises. Moreover, the rotten odor will make things more complicated.      

In case your water heater is damaged, you may not get the full claim of insurance. Sad but it is the truth. Furthermore, the warranty may include the anode rod installed. Thus, without an anode rod, even the warranty won’t work.

Most importantly, the lifespan of your water heater will decrease so noticeably. If you have removed the anode rod, the heater may serve you only for 6 to 8 years.

Whereas, it lasts 18 to 20 years having an anode rod. Therefore, do not forget to install an anode rod soon.                 

Which Anode Rod Will Secure Your Well Water Heater?

Aluminum or zinc anode rods are ideal to secure your well water heater. These are well-known for ensuring the accurate mineral level in well water.

Commonly, some homeowners prefer well water as it does not cost at all. Moreover, they do not feel safe or like the water from the city. Thus, their choice remains in the well water.

Sadly, well water carries too many minerals, which are harmful to health. In that case, aluminum plays well to keep the minerals on a safe level.   

Furthermore, well water becomes undrinkable if it has any bad smell. Zinc is efficient in reducing the smell and purifying the water. That’s why you should install an aluminum or zinc rod in your water heater according to the well water problem.          

Which Anode Rod Will Perform Better in Softened Water Heater?   

Try installing a powered or a magnesium anode rod to get better performance in a softened water heater. We recommend having a magnesium anode rod as many homeowners tend to drink the water.

Some will suggest you use an aluminum anode rod as it purifies the water. But, it won’t be a safe option for the heater tank. The tank will lose its longevity and your cost will increase. 

Moreover, a powered or magnesium rod is celebrated for reducing corrosion rate. Thus, the tank remains secure for a longer time being rust-free.

Magnesium maintains the water quality by balancing the aluminum percentage. It even adds a few advantages to drinking the water. Therefore, set a powered or magnesium anode rod for your softened water.                       

What is the Best Material Anode Rod for a Hard Water Heater?

The best material anode rod for a hard water heater is a zinc or aluminum anode rod. To reduce the high presence of calcium or other organic ingredients in hard water, an aluminum anode rod plays an excellent role.

Hard water is responsible for inviting excessive corrosion and rust in the tank. As a result, the tank lasts less than expected. Moreover, the water’s taste or appearance also deteriorates.

You must have known that hard water is a source of superfluous calcium, minerals, etc. Nothing excessive is good for your health.

Therefore, zinc or aluminum anode rod reduces the corrosion and rust possibility as much as possible. Besides, the water taste becomes normal and drinkable as aluminum or zinc balances the presence of minerals.    

So, do not delay to make your hard water safe and secure the water tank by getting a zinc or aluminum anode rod.
