What is an Anode Rod & What Happens When it Goes Bad?
Something you may not be familiar with is the Anode Rod, which is critical to the longevity of your electric water heater.Unsightly discolored water, a rotten egg stench, air in the pipes, and sporadic hot water are all symptoms of a faulty anode rod.The anode rod in electric water heaters protects the tank, and indicators that it needs to be changed include a rotten egg smell, no heat, and unusual sounds.A critical role is played by the anode rod in the operation of electric water heater tank type systems.
What is an Anode Rod
- What exactly is an anode rod, and what happens when one fails?
- The anode is a metal rod that is installed into the interior of the water heater.
- The rod serves to safeguard the tank’s steel walls by drawing minerals and silt to the tank’s interior.
- Magnesium or aluminum anode rods are used in the construction of the anode.
- Magnesium is particularly useful because it has the capacity to give electrons more easily than aluminum anodes, which makes it more efficient.
- The rod is responsible for removing silt from the tank.
The anode rod will help to extend the life of your water heater while also ensuring that the quality of the hot water that passes through your plumbing is maintained.Because it pulls out sediment, the anode rod helps to extend the life of your tank by reducing the amount of time it has to eat away at it.
Anodes and Water Quality
- The stench of rotting eggs is a solid indicator that your water quality is interfering with the anode’s effectiveness.
- The sulfur level in the water is the source of the foul odor.
- Because of this, the anode will degrade and the lifespan of your water heater will be reduced.
- Well water that has been contaminated with sulfur is quite prevalent.
- Other variables that affect anode function include the overuse of water softeners, calcium and lime buildup, and the presence of non-harmful sulfur-eating bacteria.
Recommendations for Servicing your Water Heater
- Air in the lines, a strong ″rotten egg″ smell, or discoloration in the water are all indications that your water heater needs to be serviced.
- In addition, you may hear what sounds like air, and the machine may only operate occasionally.
- Due to the holes that are being generated in the rod as the mineral content eats away at the rod, this occurs.
- This is a solid sign that your plumber will need to replace the anode rod with a new one……………………..
- Additionally, monitoring the pH level of your water will aid in the prevention of anode corrosion.
- Anode rods perform best at a pH of seven on the scale.
Flushing and servicing your water heater on a regular basis can definitely extend the life of your device as well.More information on how to maintain your water heater may be found by going here.In addition to serving Red Oak, Maypearl, Cedar Hill, DeSoto, Duncanville, and all of Ellis County, we have been voted best plumber Waxahachie and best plumber Midlothian.Call us right now at 972-937-0040.
What Does an Anode Rod Do in a Water Heater?
- The 26th of January, 2017 Every three years or so, you should replace the anode rod in your water heater, which is a critical component of the system.
- Although there are a variety of materials and components utilized in contemporary water heaters, the anode rod is perhaps the most significant of them all.
- The interior components of water heaters would wear out much more quickly if this item were not present.
- Anode rods, on the other hand, must be replaced on a regular basis since they wear out much more quickly than the water heater’s overall lifespan.
- If you have a normal tank-style heater (as opposed to a tankless kind), you should inspect the rod on a regular basis and replace it as needed.
- Here’s some more information on what an anode rod does and how it works.
Protecting Your Water Heater
- Water heaters are subject to rust and corrosion as a result of the materials used in their construction as well as the way in which these materials react when exposed to moisture.
- When water comes into touch with oxygen or moisture, the steel used to construct the tanks corrodes and rusts, causing the tanks to corrode and rust further.
- Although the heating element may make your water lovely and hot, the heat also has the effect of speeding up the corrosion process.
- The anode rod is a component of a water heater that is meant to slow down corrosion and rusting.
- Magnesium is used in the construction of the rod because it wears out more quickly than steel.
- Water corrodes the magnesium and causes it to release electrons into the tank.
These electrons form a protective barrier around the steel of the tank as a result of the corrosion.
Evaluating the Anode Rod
- The temperature of the water in the tank, the amount of water utilized, the quality of the water heater, and the composition (hardness vs.
- softness) of the water can all influence the service life of an anode rod.
- The rod, as well as the entire water heater system, will last longer if you keep up with your monthly water heater maintenance appointments.
- Once a year, have your tank cleansed to ensure that all sediment is removed.
- The anode rod should be replaced every three years, however due to the location of the rod on the tank, this is a tough task to perform on your own.
- Don’t forget to contact your local expert plumber when it is time to replace this vital component of your hot water heater.

What Is The Purpose Of The Anode Rod In A Water Heater?
- You can’t live without your water heater; it offers you with a warm spot to bathe your body after a sweaty day at work, it provides you with warmth and comfort when you wash your hands (ideally) after you use the sink, and it is what dish washers require.
- Although unlikely, your water heater will require maintenance at some point in the future, just like nearly all mechanical devices on the planet.
- The anode rod is one of the most usually disregarded or forgotten aspects of a water heater, despite the fact that it is perhaps its most crucial component.
- People have lost hundreds, if not thousands of dollars in water heater replacement costs as a result of not knowing about this device within a water heater when they should have known about it.
- Consequently, what exactly is the function of the anode rod in a water heater?
- Because it is made of a less noble material than the steel tank of the water heater, the anode rod is designed to perform less well.
This is done so that water will demolish the anode rod long before it disintegrates the water heater, hence increasing the lifespan of the water heater.Anode rods are available in a variety of sizes, materials, and price ranges, and, similar to an oil change on a car, may make a significant difference in the longevity of your hot water heater.Learn more about the anode rod and why it is so crucial by continuing to read this article!
What Is The Purpose Of The Anode Rod?
- The anode rod is a critical component of any hot water tank and should not be disregarded in its installation. The anode is a fitting that is included with almost every water heater (with the exception of tankless models) and is made of one of the materials listed below: Zinc
- Essentially, this anode rod will serve as a focal point within the tank, allowing water and oxygen to concentrate on it and eventually eat away at it over time.
- Because of the nature of this rod, it is frequently referred to as a ″sacrificial rod.″ This rod, which threads into your water heater from the top, is typically 44 inches in length, although smaller and longer lengths are available to accommodate different-sized water heater tanks.
- The rod has threads on the end of it that are sealed with teflon tape to ensure that there is no water leakage between the threads and the tank, which is extremely critical.
- If you’d want to learn more about teflon tape, I’ve written another post that goes into further detail and may be quite valuable if you ever intend on replacing your anode rod.
Why Do I Need An Anode Rod?
- According to what has been said earlier, the anode rod is quite important inside of the water heater.
- Water heaters are susceptible to naturally occurring rust, which can seep into your water supply and create leaks from the tank.
- The rod helps to prevent this from happening.
- Because it serves as a sacrificial lamb, the rod significantly increases the longevity of your tank.
- Because Zinc, Magnesium, and Aluminum are less noble metals than Iron and Steel, they decay more quickly than these noble metals.
- It is true that I am not a scientist, therefore I am unable to provide you with the most scientific explanation, but the rod will effectively give up its electrons to the oxygen and water present, which will cause it to corrode.
Steel and iron are also capable of doing this, and tanks are typically constructed from either of these two materials with a thin covering of glass to provide further protection.The reason why the anode is the first component to degrade is simply due to the fact that less noble materials give up their electrons at a faster pace than more noble ones.The use of this rod is a no-brainer when you consider how much water heaters cost, including installation.
Costs Of Replacing Your Water Heater Vs. Replacing Your Anode Rod
- The Cost of the Rod Depending on the size of the rod required and the material you choose, the rods may be rather affordable, with prices ranging anywhere from the 15-dollar level for tiny water tanks to and over 45-dollars for standard-sized heaters.
- Replace your rod without the assistance of a plumber since it only needs one instrument, the rod itself, some teflon tape, and quite a bit of elbow grease to complete the task.
- The instrument in question is a 1 1/16′′ socket wrench, and it will cost you around $25 for the wrench and the socket.
- Water heaters are expensive.
- A water heater is a more significant investment, and it may cost upwards of 600$ or more depending on your sizing needs, the brand and kind of tank you want to install (electric, gas etc.).
- The Cost of a Plumber If your water heater goes down, you will need to hire a plumber to replace it, which will be an expensive proposition.
When you include in the cost of a new unit, you’re looking at an hourly rate of between 60–150 dollars.The plumber will most likely be the one to come and get the tank for you, but he or she will almost certainly mark up the cost of the tank on the bill to account for the time, labor, and gasoline required to bring the tank back.The work might take up to 3 hours if you include turning off the water supply to the old tank, emptying it, disconnecting it from its power or fuel source and carting it away, as well as connecting the new tank, connecting it to its power or fuel source, and connecting the water.Tips for lowering the cost of a plumber’s services include: You can save a few dollars by picking up and carrying away the old tank yourself, since this will be added to the final charge when the new tank has been installed.
You may do this by turning off the water to your water heater and draining the tank. This might save you a significant amount of money, however it will take some time to complete. This position will almost certainly need some previous experience.
Note – If you’re unsure about how to complete any of the plumbing jobs on your own, it’s better to leave it to the professionals to complete them. When it comes to plumbing, you’re dealing with the possibility of water damage, leaks, and other problems that might wind up costing you money.
How Long Can You Expect An Anode To Last?
- It is recommended that you inspect your anode rod at least once every three years.
- The rods, on the other hand, will normally last a good 4-5 years before they need to be replaced completely.
- The rationale for checking the rod every three years is to ensure that it is still in good condition.
- Varied households have different experiences with different factors, such as the mineral count in the water, the acidity of the water, and whether or not there is a water softener in the house or not.
- Preventing looming tragedy by inspecting the rod early on is extremely useful to you since it allows you to nip any possible disaster in the bud.
- Spending the about 20 minutes to check, plus the around 45 dollars to replace (if necessary), might save you a significant amount of money in the long run.
What You Should Be On The Lookout For Whenever you remove the anode rod from the tank, you should check to see if any of the steel wire of the anode rod is visible.The basic rule of thumb is that if you can see visible steel wire for more than 6 inches, your anode rod has to be changed immediately.The lower the amount of ‘less’ noble metal that is accessible for degradation, the greater the likelihood of corrosion of the tank itself.
Ways To Check If The Anode Rod Is Bad
- In addition to physically turning off the water supply to the water heater and unscrewing the anode rod from the tank to visually inspect the rod for damage, there are a few more techniques to determine whether or not the rod is damaged. Exceptional rotten egg odor emanating from the hot water side – If you find that you have a distinct rotten egg stench emanating from the hot water side when you turn on the hot water from your faucets, this might be an indication that your anode is beginning to fail. Water and oxygen react with the tank’s liner, causing it to deteriorate and give off a rotten egg smell.
- If you detect the stench when you switch on the cold water supply as well, it might be a result of problems with your water treatment system, or if you don’t have water treatment, it could be a result of a problem with one of your supply lines. You should consult with a competent specialist at this time in order to establish the root source of the problem.
- Have a water softener in your house?
- Even while water softeners are intended to aid with hard water in your home, they can also react with the anode rod itself, causing it to degrade more quickly.
- Once every six months, you should inspect your rod if you have recently had one fitted, otherwise once every 12 months.
- Consider purchasing a powered anode rod, such as this one from Amazon, to soften your drinking water.
- Because this rod does not decay, it may be used for up to 6 years.
- Manually unscrewing the rod — It may be necessary to manually unscrew the rod from time to time, and in addition to the usual corrosion down to the steel wire, there may be a few more things to watch for while pulling it out of the machine. Increased calcium concentration in the water can cause calcium to accumulate on the anode rod, making the rod much less effective and causing the tank to corrode more quickly
- this is known as calcium buildup.
- There is no rust – It is also conceivable that you have fitted a rod that is just not functioning properly. if the rod still appears like it was just taken out of the box after a month in use, it is not performing its function and your tank is suffering as a result. If this is the case, you should consider purchasing a powered anode rod.
How Often to Change Anode Rod in Water Heater
- In this post, we’ll look at a critical, yet often overlooked, component of your water heater: the anode rod (also known as the heater’s anode).
- The anode rod is critical in extending the life of a water heater, but it must be serviced and replaced on a regular basis to be effective.
- We’ll tell you how often you should replace this rod in order to keep your water heater in good operating order, as well as how to do it correctly.
How often should you change the anode rod in a hot water heater?
- In this case, the most realistic response is ″whenever the rod becomes sufficiently rusted that it ceases to function″ (more on this below).
- Sadly, due to the fact that the anode rod is located within your water heater, you will not always be aware of when this occurs.
- We recommend that you examine your anode rod once a year.
- According to general guidelines, you’ll need to replace your water heater every 3-5 years, although this may vary depending on how much water is passed through it on a regular basis and the amount of corrosive compounds contained in the water.
- Following that, we’ll teach you how to determine whether or not your rod needs to be changed, as well as how to replace it.

Which is preferable?
How to Change Anode Rod in Water Heater
An crucial concern remains, however, now that we know how frequently an anode rod must be replaced: how do I replace it? To fully comprehend this process, let us first analyze what an anode rod truly accomplishes, which will assist you in determining if it has ″gone bad.″ Once you understand what an anode rod does, you will be better able to determine whether it has ″gone bad.″
First: What is an Anode Rod
- In most cases, steel or another metal is used to construct a water heater tank.
- Steel is a corrosive substance that rusts easily, especially when exposed to water on a regular basis.
- A long rod that is inserted into the top of a water heater and acts to attract and keep the corrosive components of the water away from the tank’s side is known as an anode rod or anode rods.
- Related: Rheem Water Heater – Troubleshooting Guide (Extended Edition) Due to the attraction of these corrosive substances to the steel anode rod rather than the tank’s surface, rust will not occur.
- In essence, the anode rod is ″sacrificing″ itself, which is why it is sometimes referred to as a ″sacrificial anode rod.″ The reason for this is that the anode rod has a more negative electrochemical build than the tank itself, which makes it effective.
What Happens When Your Anode Rod Goes Bad?
- Through its ability to attract the corrosive components of water toward it, the anode rod itself begins to corrode over time.
- After a certain point, the metal in the rod will corrode to the point where it will no longer have any metal left to perform its ″sacrificial attraction,″ resulting in the rod becoming useless.
- At this time, the rod is no longer functional, and the corrosive water may cause the tank to corrode further.
- It is possible that the tank will rupture in the worst case scenario.
How Do I Know if My Anode Rod isn’t Working?
- When your hot water turns stinky or discolored, this is one of the most obvious symptoms that your anode rod is no longer functioning properly.
- Due to the fact that the anode rod is no longer protecting your tank from rust and corrosion, the anode rod ends up in your drinking water supply.
- Likewise, you should inspect your anode rod at least once each year to see whether or not the rod has been corroded to the point that it is no longer usable.
- Replacement may be necessary if your rod is nearly completely rusted or if it has begun to break away.
- We’ll lead you through the process of gaining access to and removing your anode rod, as well as replacing it with a new rod, in the sections below (if necessary).
How to Change an Anode Rod
Step 1 – Beginning Considerations
- To begin, it is crucial to highlight that this is a broad guideline and should not be considered definitive.
- You must examine your unique hot water heater to see whether it requires an anode rod of a specific brand, material, or model in order to function properly.
- First and foremost, check the user handbook for your device to determine if there are any special factors that must be taken into account.
Step 2 – Power and Water
We’re just getting started now. First and foremost, you must turn off the electricity to your water heater. When using a gas water heater, this involves turning off the thermostat, and when using an electric water heater, it requires turning off the breaker. Aside from that, disconnect the water supply connection from the device or turn off the water directly at the pump.
Step 3 – Drain Water Heater
- Because we will be dealing with the internal components of the water heater, it will be necessary to partially empty it prior to beginning.
- Drain your water heater by looking for the drain at the bottom.
- An appropriate drain or an external area must be reached once the drain has been connected with an appropriate hose.
- Drain approximately 15 percent of the tank by opening the drain valve and a nearby hot water valve (i.e., a hot water source close to the heater).
- If the tank is still hot after you remove the rod, you must allow it to cool before removing it.
Step 4 – Locate and Remove
- To determine where the anode rod is located on your equipment, see the user manual.
- Most of the time, it may be accessed from the top of the water heater, where it is screwed into the appliance.
- It is almost always possible to simply remove the anode rod by hand, using a socket (and sometimes even a breaker bar) or a wrench.
- Ask someone to hold the tank in place so that it doesn’t twist while you twist the rod if the rod is extremely stuck.
- If the rod is particularly jammed, ask someone to keep the tank in place.
- Even while the rod should be very easy to remove, it may require a little elbow grease.
Step 5 – Install New Rod
- If the rod is falling apart or is nearly completely rusted, you’ll need to replace it with a new rod to prevent further damage.
- As previously said, be certain that you get a rod that is intended for usage in conjunction with your water heater.
- Metal rods may be constructed of aluminum or magnesium, which are commonly interchangeable, although it’s essential to double-check before using them.
- Installing a new aluminum anode rod or a magnesium anode rod will be straightforward once you have them in hand.
- The procedure is the inverse of the one you used to remove it.
- If necessary, use your socket or wrench to finish the process and tighten the new rod into place as tightly as possible.
- Then, reconnect the water heater’s drain valve and switch on the water supply again.
- As the tank fills with water, turn on the hot water valve and leave it open until the tank is entirely full.
- Finally, re-energize the power (if it is electric) or reset the thermostat (if gas).
- Finally, a brand-new sacrificial rod to keep your tank safe.
Why Are Anode Rods Important?
- Because it prevents corrosion in your heater’s storage tank, the anode rod can help you get more use out of your typical hot water heater.
- Get bids from as many as three professionals!
- Enter your zip code below to get matched with top-rated professionals in your area.
- This component is one of the most important components of a typical hot water heater since it aids in the prevention of storage tank corrosion and rusting.
- However, the life expectancy of your anode rod is frequently significantly lower than the life expectancy of the hot water heater itself.
- As a result, you must inspect it on a regular basis and replace it every few years.
What Is an Anode Rod?
It is a significant component of your water heater that runs along the middle of your tank and serves as a conductor of electricity. An aluminum, aluminum/zinc alloy, or magnesium wire is wrapped around a steel wire to form a ring. These products assist to keep your water heater from corroding in the first place.
What Does the Anode Rod Do?
- There’s no denying that the climate inside your water heater tank is quite harsh.
- There’s a body of water.
- There’s a lot of heat.
- There is a metal storage tank on the premises.
- Furthermore, those are the ideal circumstances for rust and corrosion to occur.
- The anode rod serves to counteract these situations, so extending the life and performance of your water heater and lowering its operating costs.
- In reality, its role is to wear itself down in order to keep the tank in good condition.
- Because of the erosion of the rod, electrons are released into the water heater tank, which helps to delay or prevent corrosion within the tank.
- As a result, the anode rod usually fails first, followed by the water heater afterwards.
- In fact, plumbers refer to the anode rod as ″the sacrificial lamb″ of your hot water heater because of its role in reducing corrosion.
Why Are Anode Rods Important?
- The performance of your water heater is dependent on the anode rods.
- For starters, they prevent your water heater from corrosion by drawing potentially harmful particles such as minerals and silt to themselves.
- However, by assisting you in keeping your water heater in good working order, they may help it last longer.
- As a result of the vulnerability of water heaters to corrosion, it is critical to examine your anode rod on a frequent basis.
How Often Should the Anode Rod Be Replaced?
- Several factors can influence how long your anode rod lasts, including how much hot water your household consumes, what sort of water you have, how hot the water is, how well the system is maintained, and what type of anode rod is installed.
- The chemistry of your water will have a particularly large impact on the length of time the rod is effective.
- For example, the more acidic your water is, the more quickly the rod is prone to corrode.
- The material from which your rod is produced also has an impact on how long it will survive.
- The majority of anode rods are constructed of magnesium, which corrodes rapidly.
- As a result, if your water is hard or contains large quantities of calcium, magnesium, or other dissolved minerals, you should avoid using magnesium anode rods in your water treatment system.
- When dealing with hard water, you’ll want to examine and replace your hot water heater’s magnesium rod more regularly, maybe as often as once every few years.
- Aluminum anode rods are a good alternative, even if they are not as common as magnesium.
- This is especially true if you have hard water.
- This type of magnesium rod is quite affordable, and it has a longer lifespan than the normal magnesium rod.
- Then there’s the electrical anode rod, also known as the ″non-sacrificial″ anode rod.
- This type of rod is specifically engineered to not rust at all.
- Instead, it transmits electrical impulses into the water heater tank, giving the same level of protection as magnesium and aluminum rods while not corroding the water heater tank.
- Despite the fact that electrical rods are more expensive, they are also the most durable, lasting for the whole lifespan of your water heater.
Checking and Replacing Anode Rods
- It is recommended that you flush and drain your water heater at least once or twice a year.
- This will not only prevent the tank from corrosion, but it will also slow the rusting and corrosion of your anode rod and other metal components.
- In addition, you should physically monitor your anode rod and the hot water itself on a regular basis.
- Water samples should be collected in a transparent glass so that they can be compared to look for evidence of rust and sediment.
- This will help you spot indicators that your tank is beginning to degrade by comparing the two samples.
- In most cases, if the corrosion hasn’t progressed too far, replacing the anode rod will address the problem and help to extend the life of your hot water heating system.
- Generally speaking, though, this is not something you should do on your own because removing the rod takes special equipment that the majority of people do not have.
- Furthermore, the rods need a significant amount of overhead clearance.
- The replacement rod, as well as the water entrance lines, are easily damaged unless you’re a skilled plumber with a lot of expertise.
- The water entry lines are normally positioned close to the anode rod, towards the top of the water heater tank.
How Much Does It Cost to Replace an Anode Rod?
- The good news, though, is that, according to HomeAdvisor, a replacement rod typically costs between $20 and $50, and hiring a professional for this reasonably short repair would cost between $50 and $150 per hour.
- The typical cost to replace a water heater may range from $800 at the low end to more than $1,500 at the high end, according to HomeAdvisor.
- The cost varies based to your plumbing system’s condition as well as the model of water heater you pick.
This underappreciated component of the typical hot water heater performs a critical function. In addition, keeping a careful check on your anode rod and replacing it as soon as it begins to break is essential for safeguarding your tank and extending the life and performance of your hot water heater.
Understanding Water Heater Anode Rods – PlumbingSupply.com
A lot of individuals take their water heater for granted, figuring they can just install it and forget about it once it is in place. This is, for the most part, accurate. Tank-style water heaters are very basic equipment that require little maintenance to function properly. as long as your anode rod is in good working order
What Is an Anode Rod & How Does It Work?
- What is an anode rod, and how does it work?
- The answer according to the dictionary is ″a sacrificial rod that is mostly used in water heaters It contributes to the preservation of the water heater’s liner and, in general, increases its lifespan.″ But what exactly does that imply in practice?
- Metals and water are used in the plumbing process.
- When these two things come together, you get something called galvanic corrosion.
- It is described as ″an electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact and submerged in an electrolyte″ when both metals are in electrical contact and immersed in an electrolyte.
- The combination of your pipe, which is made of one type of metal, your tank, which is made of another type of metal, and the water creates the perfect environment for some spectacular galvanic corrosion.
- This isn’t a good sign.
- In order to avoid rusting and corroding of the water heater tank and heater element, great plumbers and chemists of yore devised the sacrificial rod for the water heater tank and heater element.
- If you have an electric water heater, the anode rod should corrode first, leaving the tank’s metal (and element if you have an electric water heater) unaffected.
- This would save you from having to deal with a rusted monster that leaks at odd intervals.
- This is possible because the anode rod has a lower electrochemical potential than the steel component of the water heater, resulting in a larger negative electrochemical potential.
- A larger voltage is created by the negatively charged electrons, which causes a stronger current to flow from anode rod to steel tank, resulting in the anode rod corroding instead of the steel water heater tank or other exposed metals such as electric components.
- The anode rod is a ″self-sacrificing″ component that will continue to corrode until it is finally removed and replaced with another.
- It is possible for the tank to rust if there is no sacrifice metal left on the anode, which is why it is so vital to change yours on a regular basis.
It’s a good idea to flush your water heater out as well while changing your anode rod to remove any sediment, rust, or gel build-up that may have developed at the bottom of the tank while you were replacing it.You may also want to consider cleansing your water heater at least once a year as part of your regular maintenance routine.
How Do I Check My Anode Rod?
- Look through your heater’s literature to find out where the rod is situated and how to remove it.
- This information should be contained in your unit’s handbook.
- If you don’t have the instructions, it shouldn’t be too difficult to replace the anode rods because they are usually labeled on the top of the machine and are secured in place with a hex nut.
- Once the rod has been loosened (with a crescent wrench, channellocks, a socket wrench, or other tools), it should come out in one piece.
- It’s probable that your anode rod is hooked to the hot water output if your water heater doesn’t have a separate hole for it.
- Make a hole in the flex supply to the hot water exit, which should allow you to unscrew the anode rod and take the rod out to examine the connections there.
How Do I Know When To Change Mine?
- The majority of anode rods that are pre-installed in water heaters are made of aluminum or magnesium and are wrapped around a stainless steel cable to prevent corrosion. Checking your anode rod will most likely reveal some pitting or microscopic holes, which is precisely what you should be looking for. However, in order to keep your tank protected, the anode rod must be changed when a significant portion of the wire becomes visible. Delaying maintenance is not a smart idea since a depleted anode rod will reduce the service life of your water heater significantly. Another issue with waiting too long is that it might lead to burnout. Anode rod breakage and subsequent fall to the bottom of the water heater are possibilities with an old water heater. Doesn’t seem so horrible, does it? What do you think? Unfortunately, this results in the issue of the loose anode rod bouncing about within the water heater being a nuisance. This is dangerous because it will cause fractures in the heater’s glass lining, enabling the underlying metal to corrode and dramatically lowering the unit’s life expectancy and efficiency. Generally speaking, anode rods have a life expectancy of around five years, although this is dependent on a number of factors, including the quality of your water and how much of it passes through the heater. A water softener, for example, can cause anode rods to corrode more quickly if sodium is added to the water. If the water is over-softened, anode rod corrosion can occur in as little as six months! If you have a water softener, be careful not to over-soften the water, and check the anode rod more frequently if you do (at least every six months). If any of the following apply to your case, you should replace your anode rod immediately: It generates a loud or repeated popping noises as the water heater is getting ready to heat.
- The water heater has been in your home for more than 5 years, and you have never replaced it.
- When you wipe out the aerators on your faucets, you notice a sticky gel material.
- The corrosion of aluminum anode rods can result in an aluminum oxide deposit, which is often seen at the bottom of water heaters but can occasionally be discovered in the main water supply and in faucet aerators as a result of the corrosion.
- Aluminum oxide solidifies to produce a practically odorless ″gel″ material that can range in texture from a firm, somewhat sticky curd to a thick, runny slurry, depending on the concentration of aluminum oxide used.
- The gel can be either milky or clear in appearance, and it is frequently found in conjunction with other water heater deposits such as scale, rust, or microscopic sediment particles, among others.
- Your hot water begins to smell like ″rotten egg″ after a while.
- It is possible that naturally existing iron bacteria in the water is causing an unpleasant taste or odor to emanate from your hot water outlets.
- This situation is more frequent in private or municipal well systems than in public well systems.
- Although iron bacteria in well water are not known to cause disease, according to the Minnesota Department of Health (Iron Bacteria in Well Water), they can generate an unpleasant smell, stains, and tastes in the water.
- Iron bacteria does not produce hydrogen sulfide, which is responsible for the odor associated with ″rotten eggs,″ but it can create an environment in which sulfur bacteria can develop and produce hydrogen sulfide (the rotten egg smell).
- A reaction between magnesium or aluminum anode rods and certain water conditions will result in the production of a ″rotten egg″ stench.
- By substituting a mixed aluminum/zinc/tin anode rod for a magnesium or aluminum anode rod, you may be able to reduce the odor, but it may not be fully eliminated.
- This is what your existing anode rod should look like.
How Do I Choose the Right Replacement Anode Rod?
- For changing your anode rod, you have a variety of alternatives, with the most popular being magnesium, aluminum, or a mix of aluminum, zinc, and tin as the most common anode rod materials.
- (An aluminum rod is included as standard equipment in the majority of water heaters.) It will depend on three factors when determining which rod to use: the quality of your drinking water, the position of the anode rod, and how simple it is to reach the installation spot.
- A rod made of aluminum or magnesium should be sufficient unless your water is very iron-rich.
- Aluminum is the most durable and least priced of the available materials.
- Magnesium corrodes at a somewhat higher rate than aluminum, yet drinking water with dissolved magnesium has a number of positive health effects.
- If you have water that has a high concentration of iron bacteria, which results in a ″rotten egg″ odor, we recommend using an aluminum, zinc, or tin rod since it can assist to inhibit the growth of the iron bacteria in the water.
- As previously noted, you may have a water heater that has a separate intake for the anode rod, or your anode rod may be positioned on the hot water exit of your water heater.
- Because the majority of water heaters use a standard 3/4″ NPT connection, you just need to consider the sort of installation you currently have..
- It is always possible to put a new anode rod on the hot water outlet if you have a separate inlet for the anode rod but are unable to remove the old one or the connections are too corroded to attach the new one.
- Advice from the experts: Even if you put a new anode rod on the separate intake, you should consider adding another anode rod to your hot water exit as a backup for even more safety.
- In the event that you have limited ceiling clearance or problematic access spots for installing your new rod, flexible rods may be an option for you.
- You may just bend them along the specified portions of the tank in order to slide them into the tank, straightening them as you move them into the tank.
- Following our explanation of anode rods’ superiority, why not get out there and inspect your own?
- And keep in mind that if you take good care of your anode rod, your water heater (and you) will take good care of themselves.
- Please keep in mind that the material presented here is designed to provide a fundamental understanding of plumbing-related repairs, troubleshooting, and purchase considerations.

What Does the Anode Rod Do for Your Water Heater?
- What would you say is the most significant home comfort appliance in your house if we asked you to identify the most important one?
- If you indicated it was your water heater, then we are absolutely on the same page!
- The water heater in your house is a real workhorse that gets the job done.
- It offers you with the hot water you require for a variety of tasks such as showering, washing dishes, doing laundry, and so on.
- Even if you’re not familiar with the term ″anode rod,″ it’s a component of a tank water heater that is critical to making it all work, even if you’ve never heard of it before: the anode rod.
- It is true that the anode rod isn’t a familiar term, but it is quite crucial in homes that have storage tank water heaters.
- After all, it performs a vital job for the body.
- The anode rod, on the other hand, does not endure the whole lifespan of the water heater, thus it is critical that you understand the status of yours.

What Is the Anode Rod?
- This is essentially a rod that is placed into the tank of your water heater to provide heat for the water.
- It is by design that magnesium is the most usually used material for this component.
- Magnesium degrades far more quickly than steel, and steel is used in the construction of hot water tanks.
- So, why would you want a magnesium rod to begin to corrode in a steel container?
- So that the steel doesn’t get in the way!
Protecting the Water Heater Tank
- Steel is a very valuable material, but it rusts and corrodes with time, and it is no longer usable.
- It’s likely that you’re already aware of this.
- It’s a simple matter of chemistry: water causes metals to corrode.
- Your tank water heater’s maker is also aware of this, which is why the tank has a couple of lines of defense built into it to protect you from potential threats.
- An internal glass layer protects the tank’s interior as its first line of protection.
- In a modern water heater, this coating prevents water from even coming into touch with the steel of the tank’s storage tank.
- As a result of this, the water within the tank may reach the steel that it is made of, and at that point, the anode rod ″jumps into action,″ as the saying goes.
- In comparison to steel, the rod begins reacting to the corrosive components of water more quickly than steel does.
- So the anode rod gets depleted by this material first, which protects the tank itself from corrosion in the process.
- By the way, the anode rod is also referred to as the sacrificial anode rod in some circles.
- It’s not difficult to understand why, is it?
- Because the anode rod deteriorates with time, it also indicates that it will not endure indefinitely, as we said above in passing.
- Maintaining a properly functioning anode rod is critical to the protection of your hot water tank.
- Once the tank begins to corrode, the only alternative is to have it replaced completely.
So, what does all of this imply?Don’t be concerned about visually inspecting the inside of your water heater; we do not expect you to do so.No, instead, this indicates that you should schedule yearly maintenance for your tank water heater, which will include checking the anode rod and replacing it if it is damaged.

Everything you Need to Know About a Water Heater Anode Rod
- The 13th of December, 2019. What is the purpose of a water heater anode rod? An anode rod is a temporary steel core wire that is surrounded with magnesium, aluminum, or zinc to provide corrosion resistance. It is only designed to be in use for a limited amount of time before being replaced with something else. Alternatively, if you already have an anode rod, it is critical that you suction it out in order to avoid future issues. An anode rod is a piece of metal that is used to protect the metal liner inside of your water heater tank against corrosion and explosion over time. What Metals Are Used in Anode Rods and How Do They Work? Anode rods are often made of metals such as magnesium, aluminum, or zinc
- however, they can also be made of other materials.
- It is predicted that magnesium anode rods will perform better in a residence with soft water.
- Aluminum anodes are recommended for use in houses with hard water and a high PH level.
- Zinc anodes are the most effective when a home is beginning to smell like rotten eggs, and they are also the most effective when replacing water heaters that have disintegrated.
- A good rule of thumb is to check an anode rod once a year.
- Before we get started, an anode rod’s lifespan is determined by a variety of circumstances, including whether you have hard or soft water.
- However, you should call Nebrasky every two to five years to check on the state of the rod and determine whether it’s time to replace it before the rod dissolves.
- The anode rods in a water heater are one of the most crucial equipment in a household.
- Inadequate inspection and/or replacement of one can result in a serious problem.
- Maintaining your anode heater at least once a decade will help you save money and avoid a water heater from overflowing.

What does an anode rod do in a water heater?
- Aluminum, magnesium, and zinc are among the metals in this category.
- In addition to protecting your water heater from rusting, the rod is also useful for other purposes.
- In order to protect the exposed steel of the water heater’s tank, the anode rod sacrifices itself by using a process known as electrolysis when the tank is fully filled with water.
- More information about this may be found by clicking here.
- Also, how long does an anode rod last in a hot water heater is an often requested question.
- about three to five years How frequently should the anode rod in a water heater be replaced?
- You will typically need to replace the anode rod in your water heater roughly once every 6 years if it is operating under regular operating circumstances.
- It is possible, however, that you will need to replace the anode rod more regularly depending on the makeup of your water.
- Is it necessary for me to install an anode rod in my water heater in this regard?
- The Anode Rod is a mysterious, yet necessary, component of a water heater system.
- It keeps rust from forming in the tank of your water heater, and in order to do so properly, it should be updated every two to three years by experienced Littleton, CO plumbers.
- If this is not done, your water heater may be forced to be replaced sooner rather than later.
- When it comes to replacing a water heater anode rod, what should you expect to pay?
- In the case of a tank that lasts 10 years and costs $800 to build, the annual cost is $80.
Typically, one anode is included with each tank; this will last four years in typical water conditions before it has to be replaced.Let’s say you charge $100 to replace the rod in question.

- Consider this: your water heater has just one basic duty, and that is to heat the water that is being used.
- This is accomplished mostly successfully by carrying heat through metal and warming up liters of water, which is then circulated around your home when you turn on the faucet.
- However, this goes against everything you’ve ever been taught — after all, water corrodes metal, right?
- Or were your mother’s warnings that keeping your bike out in the weather would cause it to rust just a bunch of nonsense?
- No, this is not a fabrication.
- If you didn’t have a short rod placed into the top of the water heater, your water heater would be a collapsing pile of rubble if you didn’t have a rod.
- Known as an anode rod (or sacrificial anode rod in certain cases), this rod is the sole reason your water heater hasn’t left you swimming in rusty water after a short period of time.
- Rust, often known as corrosion of metal, occurs when three elements come together: iron (or steel), oxygen, and water.
- All of these things may be found in abundance in a water heater tank.
- However, even though contemporary water heaters have a thin coating of glass covering the tank, water may still seep into the fractures and corrode the tank of the water heater itself.
Because of this, water heater manufacturers incorporate anode rods into their products.Anode rods are composed of magnesium or aluminum, depending on the application.Magnesium and aluminum are both less-noble metals, which means that they corrode (rust) more quickly when exposed to water.
Please don your lab coats and join us as we study this topic further in depth.The chemical mechanism that leads to rusting begins with oxidation, which occurs when iron loses two of its electrons to the oxygen present in the tank throughout the storage process.The same thing happens when you submerge a magnesium or aluminum rod in water; however, it happens much more quickly.
- The links between the molecules of magnesium and aluminum lose electrons at a greater rate than the bonds between the molecules of steel or iron.
- Because the oxygen in the equation gives up electrons more quickly than the iron or steel in the tank, when you insert an aluminum or magnesium anode rod in an iron or steel tank of water, the oxygen in the equation gets the two electrons from the anode rod instead of the tank.
- The anode rod will corrode as a result of this, but not the tank itself.
- Essentially, the anode rod rusts more quickly than either the iron or steel of a tank, which results in the tank being corrosion-free until the metal of the anode rod has fully rusted away.
- The term ″sacrificial anode rod″ refers to the fact that the rod is intended to be used just once.
- It is willing to give up its life in order to save the tank’s liner.
It will eventually rust away to the point that all of the magnesium or aluminum in the rod will have rusted away, and it will have run out of electrons to give up to spare the electrons in the tank from the rusting process.When the anode rod has corroded away, the tank of the water heater may begin to rust, which will cause the water heater to fail – and you’ll be forced to spend hundreds of dollars on a fresh new water heater to remedy the situation.Because of this, replacing or at the very least inspecting your anode rod every three years is critical.
Check the manufacturer’s guidelines to determine when an anode rod replacement is required for your specific water heater.Do you have any idea how old your water heater is?Take a look at this article.
Even if you have a house warranty that covers your water heater in addition to other systems and appliances in your home, it’s vital to remember that a home warranty will not cover the cost of repairing or replacing a rusty water heater if the anode rod has not been maintained correctly.If, on the other hand, the water heater breaks due to regular wear and tear, a home appliance warranty will cover the cost of repairs or replacement – all you will be responsible for is a service call charge.More information on house warranties, including how they may cover your plumbing and water heater, can be found by browsing through our home warranty programs.If you’re interested in learning more about your water heater and plumbing, our plumbing resources can help you locate more of what you’re searching for.
The sacrificial anode: what is it? When should you replace it?
Which product would you like to receive a quotation for? For more than one product, you must submit a separate request for each product you wish to receive a quotation on. Tips and hints for closing
The sacrificial anode is an essential component of your water heater. It’s a long metal rod, made of magnesium or aluminum, which extends through the tank’s interior.
- This is accomplished by an electrochemical process in which it attracts particles of iron, limestone, or other minerals present in the water and corrodes them in place of the tank.
- For want of a better expression, it ″sacrifices″ itself in order to extend the life of the water heater.
- Most water heater manufacturers would recommend that you evaluate the status of the sacrificial anode every one (1) to three (3) years and replace it when it has been consumed by more than 50% of its original capacity.
- Those who have hard water or who use a water softener should be extremely cautious.
- But proceed with caution!
- The replacement of your water heater’s anode rod on your own may violate the appliance’s warranty in some circumstances.
- Before doing this procedure, make sure you understand the conditions of your warranty or speak with your supplier.
Where can you find a new anode for your water heater?
- Replacement anode rods for typical water heater types are readily available at most hardware stores and supermarkets.
- Aluminum anode rods are the most prevalent form, and their average price ranges from $20 to $40 per pound of aluminum.
- Before purchasing the anode rod, make a note of the model number of your water heater as well as the tank capacity (in gallons).
- Compact water heaters and water heaters that hold more than 60 gallons will almost certainly require a special order.
How do you check the condition of the sacrificial anode?
- This is necessary because the sacrificial anode is immersed in the tank and must be drained before the water heater can be inspected
- Depending on the type, you’ll either have to drain the water heater partially or fully, depending on the situation. Before you begin, double-check that you understand how to carry out the draining procedure. Then take the following steps:
- To begin, switch off the electricity to your water heater.
- To determine where the anode rod is located, go to the manufacturer’s handbook. The position of your water heater is determined by the model of your water heater. The majority of them are accessible from the top of the appliance, where they are concealed behind a plastic cap. It is possible that you will have to remove insulating material in order to get to it.
- Drain the tank, at least half, at this point.
- With a 1 1/16-inch socket wrench, remove the corroded anode rod from the circuit. Because the rod may be quite hot, it is suggested that you wear work gloves for this step. You might expect some resistance at first until the worn-out anode is released
- this is normal.
- Install the replacement anode and restart your water heater when you have completed the draining procedure, as follows:

What Does the Anode Rod in My Water Heater Do?
- Water heaters are an absolute need in today’s world. However, most of us are only vaguely aware of how they function beyond the most fundamental concepts. Although we are aware that water is drawn into the cylinder from the mains, that it is heated, and that the temperature is maintained by adequate insulation surrounding the cylinder, we know very little more about them. The majority of the other components remain a mystery to us. For example, what exactly is an anode rod and what exactly does it do? What Is the Function of an Anode Rod? The term ″anode rod″ or ″sacrificial anode rod″ may be used to refer to the same object, but they are not synonymous. In this case, it is a metal rod that has been extended into the water heater’s cylinder. It is designed to serve a single purpose: to attract corrosive materials and keep them from causing harm to the inside of the cylinder. A current of electricity passes through the rod, charging it and attracting particles that have the opposite charge to the current. As the particles accumulate, the rode begins to corrode, finally succumbing to the damage and necessitating its replacement. What is the composition of an anode rod? Anode rods are often composed of metal, however they can be formed of a variety of metals. Magnesium, aluminum, and zinc are the most common metals used in their construction. Each metal has a distinct characteristic that distinguishes it. When it comes to anode rod fabrication, magnesium is the best-performing metal available, but it is also the least robust. It creates around 1.6 volts in the cylinder, although it may need to be replaced once a year if your water is extremely hard or soft, as is the case with certain people. Aluminium — When it comes to anode construction, aluminum creates 1.1 volts and occupies a middle-of-the-road position. The unit will require yearly inspection, but it will often only need to be replaced every five years or so, depending on how well it has held up. Zinc is the least efficient of the materials, producing only 1.05 volts when exposed to sunlight. It has a lifetime that is about equivalent to that of aluminum. What Happens if an Anode Rod Fails in a Battery? In other words, what happens when your anode rod inevitably reaches the end of its useful life? Is your water heater not operating properly? No, but the process of failure is speeded up as a result. The anode rod protects the cylinder walls against corrosive chemicals by preventing them from being attacked. Because of this, those corrosive substances get to work eating away at the interior of your cylinder, gradually leading to major issues and, finally, failure. Anode Rod Failure Warning Signs and Symptoms How can you determine if your anode rod has failed and needs replacing? Once a year, you should have a water heater maintenance provider come in and check things out for you. This is the only way to ensure that you will be able to repair the rod before it totally breaks, therefore extending the lifespan of your water heater and saving you money. However, there are certain telltale symptoms that your rod may have already failed that you may look out for. It’s possible that it’s too late to preserve the cylinder at this point. Water heaters making popping sounds while in operation
- clogged faucet aerators
- slimy gel on faucet aerators
- water is warm but not as hot as it used to be
- and water is not as hot as it used to be are just a few of the symptoms.
