How to Add Hydrogen Peroxide to a Water Heater
Whenever a circuit breaker trips and needs to be reset, the water heater is prevented from receiving energy and from operating correctly. if your water heater continues tripping the circuit breaker, you should call a professional to inspect the water heater and the circuit breakers itself to ensure that there are no other electrical appliances using the same circuit breaker.
What Causes Rotten Eggs Smell in the Water Heater?
Biological sulfate-reducing bacteria in the water are responsible for the rotten egg smell. Soft water is often treated in order to eliminate residues of potentially dangerous metal ions such as magnesium and calcium from the water. Water heaters are equipped with anodes (also known as sacrificial anodes) that attract these hazardous metals. The anode degrades over time as a result of its interaction with the hazardous metals. The bare anode rod combines with the natural sulfur present in the water to produce an electrochemical reaction.
When bacteria proliferate in water, hydrogen sulfide is released into the atmosphere.
What long-term Options Do I Have to Remove Sulfur smell in the Water Heater?
Longer-lasting benefits on lowering the sulfur odor in your water heater can be obtained by replacing the sacrificial magnesium anode rod with an aluminum-zinc alloy anode rod or with a zinc anode rod. Powered anodes degrade at a slower pace than sacrificial anodes as well. Metals such as aluminum and zinc have lower reactivity than magnesium. Due to the fact that it corrodes less, you will have:
- Less smelly water in the environment
- Lower maintenance expenses
If everything else fails, you may always try to deal with the problem at its root cause. Installing a water filtration system will help to lower the amount of bacteria in the drinking water. As a result, the water in the heater can remain bacteria-free for extended periods of time or take longer to begin creating hydrogen sulfide. The use of chlorine in water treatment lowers the amount of sulfur-reducing bacteria present. In water, chlorine interacts with the ferrous metals and causes them to oxidize.
If your water originates from a ground source, such as a well, this approach is advantageous.
Does Hydrogen Peroxide Treatment Work with Hard Water in a Water Heater?
If you have an odor in your water heater, hydrogen peroxide can help you get rid of it. If you have hard water, on the other hand, you will have greater anode damage. Hard water is simply water that has a greater concentration of calcium deposits. If your water comes from a groundwater source, such as a well, you may have hard water on your hands. Hard water will not only accelerate the deterioration of your anodes, but it will also have an adverse effect on your valves and faucets. In most families, the smell of rotten eggs is a regular concern.
Additionally, it ensures that the treated water is suitable for domestic use.

How to Eliminate Water Heater Odors
The presence of sulfur or “rotten-egg” aromas in water heaters and corrosion-prone iron pipework can occur even when the water is chlorinated municipal water. This is most often the case when the water has a low chlorine residual, high sulfate levels, and/or has been sitting dormant for several days or several weeks.
Odors Are Often Caused by Bacteria
When there is an accumulation of sulfates and bacteria in water lines, this might result in rotten egg odor or black water in the pipes. This can also result in odours coming from the hot water tank or water heater. If you are trying to figure out where the scent is coming from, it is crucial to examine if the stench is coming from the cold water or only the hot water. Run the hot water for a few minutes to detect the odor. Then go to a different faucet and turn on the cold water. An odor in cold water indicates that it is coming from somewhere in the cold water.
- In this circumstance, a water heater odor remover would come in handy.
- Although it is possible that the chlorine residual will be quite low in some situations, this is especially true if your home is located at the end of the distribution system and far away from the point at which the chlorine is initially injected at the water treatment facility.
- In spite of the fact that certain municipal water treatment plants may produce odor-free water, water entering a pipeline from one of these plants may develop smells once it enters a distribution line.
- Increased bacterial growth depletes both the oxygen and the chlorine residual in the pipe as a result of the increased bacterial growth.
- Even in cold water pipe in the home, particularly in galvanized iron piping, odors can develop and become offensive.
- The best course of action in the case of an odor in the cold water when the source is chlorinated municipal water is to trace the pipe and determine if it is iron piping, and then replace it with copper.
Depending on whether the foul-smelling water returns, it may be required to replace the old galvanized iron pipe with copper piping. (If you’re interested in learning more about water heater odors, check out this post)
Water Heater Odors
The majority of scents noticed in city water are due to the smell of a water heater. It’s possible that the sulfur or “rotten egg” smell in your hot water is being created directly in the water heater. To get rid of the sulfur smell from the water tank or if your hot water heater has a sulfur smell, you should consider disinfecting the tank with hydrogen peroxide. Cathode-anode reactions, which occur in almost all water heaters, create surplus ions that wear away the anode rod and attach to the interior glass lining of the heater, preventing corrosion from occurring.
If the cold water does not have any scents, but the hot water does, a thorough sanitization of the water heater tank using 1 to 2 pints of store-bought hydrogen peroxide can remove the odors and aromas from the water heater and restore its functionality.
Please do not do this yourself if you are not familiar with the capabilities of your water heater.
No warranty or guarantee is stated or implied in the provision of this material, which is only for informative and educational purposes.
Procedure for Sanitizing of Hot Water Heater: How to put Hydrogen Peroxide into Water Heater
Start by turning off the manual switch if your water heater is powered by electricity. When using a gas heater, set the control to Pilot. When you are finished with the operation, make sure the pilot light is still burning so that you may turn on the water heater. Secondly, turn off the cold water supply valve at the water heater. 3. Open a nearby hot water faucet as well as the T P (temperature and pressure valve, which is situated on the top of the water heater) valve to release pressure from the water heater’s tank.
- If there is no open drain near to the water heater, a hose linked to the drain valve should be used.
- Some drain valves will leak after the process has been finished, and in these circumstances, a hose bib cover can be put on to the end of the drain valve to prevent the need for a new drain valve installation.
- The following is an alternative simple method: Use the Water Heater Odor Killer Kit.
- Inspect the anode rod to provide the best possible outcomes and to prolong the life of your heater.
- Figure 3: Cut-away view of a typical gas water heater, showing the anode rod and cold water dip tube 7.
Re-plumb the water heater and turn off the temperature control valve.
Fill the water tank with cold water by opening the cold-water input at the heater.
When the tank is completely full, close the inflow valve.
Allow 1 to 3 hours for the peroxide mixture to sit in the heater.
After a few hours, reopen the cold water valve and all of the hot water taps to allow the peroxide mixture to thoroughly clean the hot water supply pipes.
Allow 15 minutes for the water to settle in the tank.
Close the drain valve if it is open.
Make certain that all air has been removed from the hot water pipes from the open hot water faucets.
15. Re-engage the manual electrical switch or return the gas control knob to the “On” position, and check to see that the heater burners have re-ignited and are operational. 16. Inspect the heater to ensure that it is operating normally.
If the Odor Returns to the Hot Water
This process will nearly always be successful in getting rid of the stench when it is done. The sanitizing technique might be repeated, if the problem recurs within a few weeks of the initial treatment. Although the cold water will often have less odor concerns than the hot water, this is often owing to the continuous presence of sulfate bacteria and low chlorine residuals in the water. Some more solutions for dealing with sulfury scents in the water heater are as follows: 1. If you haven’t already done so, remove the conventional magnesium anode rod and replace it with an aluminum or zinc anode rod if necessary.
Switch to a water heater with a plastic liner, an instantaneous water heater, or a commercial stainless steel water heater in lieu of the existing one (none of which have anode rods).

How/where to put hydrogen peroxide in water heater
10k people have asked and seen this question. I’ve recently moved into a house with two water heaters, which is great. The second one was used either sometimes or never at all by the previous owner, and all of the hot water that comes out of it is foul-smelling. This was discovered during the inspections, however the inspector said that it was due to the drain traps drying up, which resulted in the stench of sewage gases. That was a lot of sewage gas, but I’m getting ahead of myself. Moreover, it is worth noting that the hot water heater in issue is quite recent, having been installed as part of an extension that was completed no more than ten years ago.
- The house does not have a well; instead, it relies on city water.
- To go back to the subject, I’ve read in a few places that replacing the anode, as well as adding hydrogen peroxide to the hot water heater tank, are both recommended.
- Unfortunately, I have not been able to locate any information on how to get the hydrogen peroxide into the hot water tank.

- a total of eight silver badges 19 bronze medals were awarded.
- Following that, you have two options: Pulling the anode is perhaps the best option because it is possible that it has disintegrated.
- I’ve never had a problem like this before that flushing and changing the anode did not resolve.
- Only one thing to keep in mind: If you turn on a tap in the home that has both hot and cold water running while the system is open, water may come out when the cold pressure returns via the hot line.
- answered 16th of April, 2016 at 14:53 Ed Gold badges awarded to BealEd Beal93.1k4.
I don’t have a filter in it, but all I have to do is shut off the water to the hot water tank (before the filter), open the hot water faucet to relieve pressure, unscrew the bottom of the filter, dump out the water and add a bottle of hydrogen peroxide, and screw the bottom of the filter back onto the filter.
Allow for 1 – 2 hours of resting time. Walla! Once a month should be plenty to keep everything under control. answered Posted on September 28, 2018 at 22:07 ShawnShawn211 bronze badge1 is a personal achievement.

How to Add Hydrogen Peroxide to a Water Heater1070Views8 (Easy Steps) on How to Add Hydrogen Peroxide to a Water Heater As a result of the bathing experience, we can detect the slight odor of sewage water in our bathroom. We begin to believe that the water is interacting with our floor tiles, but this is not the case. Then, one exhausted evening, we decide to take a bath to help ourselves relax, only to find that the water in the tub has a strong odor of unclean water in it, which we immediately discard.
- It is important to understand how to add hydrogen peroxide to water heaters since this information may assist us in keeping contaminants out of our hot water and preventing them from forming.
- However, if this begins to happen to our heated water, it is likely that a reaction is taking place within our water heating system as a result.
- Normally, softened water collects hydrogen sulfide gas, which gives out the odor associated with filthy water.
- A form of water that has been treated to eliminate calcium, magnesium, and some metal cations found in hard water, is referred to as soft water.
- In our water heater system, the anode rod is a component that attracts corrosive elements present in the water.
- The anode rod’s function is to act as a sacrificial element, absorbing or attracting corrosive elements present in the water.
- When it has nothing more to give, it will begin to exude a fragrance that will go to our warm water.
- Aluminum anode rods are the most popular type of anode rods that are included with our water heater.
- The fact that metal is packed with our new water heater is due to the fact that aluminum is quite inexpensive.
- The usage of hydrogen peroxide, on the other hand, is intended to attack sulfur bacteria.
- When it comes into touch with our water heater, it has the potential to turn it into a breeding ground, boosting the production of hydrogen sulfide fumes.
Add hydrogen peroxide to the tank cleaning solution in order to get rid of the odor generated by bacteria in the tank. Here are eight simple procedures to follow in order to add hydrogen peroxide to our water heater:
- It has to be turned off. It is not safe to work on electrical repairs without first turning off the power. The same may be said with gas water heaters. We may switch off the electric water heater by using the circuit breakers, or if it is a plug-in kind that can be easily unplugged from electrical sockets, we can unhook it. We must make certain that the gas is turned off from the pilot
- Drain the water heater tank fully and then close the valve when we have finished draining. Make certain that the water has cooled down before draining it away to avoid third-degree burns. Make use of hydrogen peroxide at a concentration of 3 percent. Following this, a precise measurement of 2 quarts per 40 gallons should be used. Regardless, the size of our water heater tank will be a consideration. Add it to our holding tank. Fill the tank with cold water by turning on the cold water supply. Allow the water to soak into the hydrogen peroxide solution. Do not turn on the heating until you are ready. This is done in order to allow the hydrogen peroxide to take care of the foul odor. Allow it to sit for around 2-3 hours to have its maximum impact. Empty the tank with water. After waiting 2 hours, turn on our hot water faucet as well as our cold water valve to flush out the tank and allow it to drain completely. This will not only clean the tank, but it will also clean our pipes. Fill the tank with gasoline. When we no longer detect the odor of filthy water, we may refill the tank and put it back into use. Examine the aroma emanating from the hot water faucet. If the odor is still there, keep draining the water heater tank until it is completely empty
- Then turn on the electricity. When you’re finished, reconnect the power supply to our water heater and turn it back on. Keep an eye out for signs that the odor has been gone from the hot water.
Heated environments, contrary to popular assumption, do not always destroy microorganisms. In this instance, sulfur bacteria flourish in heated water tanks, where they colonize and produce hydrogen sulfide gas over time. Having a better understanding of how to use hydrogen peroxide in our water heater will make our lives easier when it comes to cleaning out our water heater tank. At least once a year, it is recommended that we maintain our water heater by executing a routine clean-up in its tank.

Why and when to flush a hot water heater
One of the most common causes for flushing is that your hot water has turned rusty or brown in color. Typically, the brown hue indicates a buildup of material inside the tank, which can be caused by rust particles from piping, water softener resin, sand and clay sediments, and other earth-based elements. As a result of the house plumbing being connected to the water mains, which are often made of steel or cast iron pipes, there will be an excessive amount of rust deposited in the tank. Because of the rotten egg smell, flushing should be performed.
The only method to manage the odor of the water is to eliminate the bacteria that causes it to smell.
Using a delimer solution in conjunction with tank cleaning can help to reduce the amount of lime and sediment build-up in your water heating system.
Flushing your water heater also extends the life of the appliance.
When is the best time to flush
In order to answer the question of how often to flush a hot water heater, simply follow the manufacturer’s recommendations, which are typically once every six months to one year.
The flushing schedule is also determined by the water quality in the area. If the water is hard and includes a high concentration of minerals, you may need to flush more frequently. Draining 1 to 2 gallons from the drain valve on a monthly basis is the very minimum needed.
Required tools for the DIY project
- Screwdriver, hammer, Teflon tape, garden hose, shop-vac, ball valve, and fittings are among the tools you’ll need.
Flushing electric and gas water heater – Step by step guide
- If you’re using a gas water heater, make sure the gas control valve is in the “OFF” position. You may also turn off the gas supply to the heater by turning off the valve on the gas line. If you’re using an electric heater, make sure the electricity is turned off at the circuit breaker (breaker box) first. Turn off the cold water supply to the heater at the main shut-off valve to prevent the heater from overheating (usually installed near the cold water inlet). It can be distinguished as a valve with a lever (ball valve) or as a valve with a wheel (gate valve) on it. To avoid a vacuum from building in the heater while it is being drained, turn on the hot water faucet. Drain the heater by attaching one end of a garden hose to the drain valve and the other end to a floor drain or the exterior of the house. The process can be accelerated if you open the TPR valve, which is located in the upper portion of the device, and place a bucket underneath it to capture the water. The water should be flowing from the relief valve, and if it is not (because it is clogged), it should be replaced with a new one that meets the same specifications. Drain them until the water flows clear and free of particles if you want to eliminate sediments from the system. If the situation becomes worse than you anticipated, you may be forced to drain the tank altogether. Bring the cold water into the heater back up to temperature. Make sure there is enough water flowing through the heater and out of the drain valve. For five or ten minutes, flush the heater with water. While refilling the tank heater, close the drain valve and leave the tap open. Once the tank is completely filled with water, open the pressure relief valve to bleed the air out of the tank.
Following that, follow the directions on the device’s label to relight the pilot or restore power to the unit. If you have an electric model, it is absolutely necessary to maintain a full tank of water since if the heating element is exposed to air, it will quickly become inoperable. Alternatively, you may go to this video instruction for assistance.
Flushing with chlorine
Flushing a water heater with the proper dissolver, such as chlorine, through the drain valve supplied at the bottom of the heater is one method of controlling and eliminating germs from the heating system. The following is the right technique for chlorinating a heater, as advised by the Bradford White company:
- Turn off the water, electricity, and/or gas supplies to the heater
- And Drain several litres of water through the drain valve, which is situated at the bottom of your heater. Remove the anode rod from the circuit. Pour 1/2 to 1 gallon of bleach into the water heater through the hot water outflow port
- Let stand for 5 minutes. Install the replacement anode rod or, if the old one is still in good working order, bring it back
- Reconnect the hot water supply line to the heater’s outlet once it has been disconnected. To check for chlorine smell, turn on the water supply and draw water from every hot water fixture in your home until the scent is noticed. Keep in mind that the treatment must be applied to all of the plumbing lines. Once the chlorine odor is detected, turn off the taps and let the bleach to rest in the heater and plumbing lines for at least 3 hours, preferably for an entire day
- Make a thorough flushing of your home’s pipework by turning on and drawing water from each tap to remove any chlorine from the system until the stench is no longer there. Turn on the electricity and/or gas supply to the heater
Softeners, prolonged periods of little water flow, and the usage of a well supply are all possible sources of the bacteria’s existence. As a result, shock chlorination of the heating system is highly suggested in this situation. If you have a badly diseased system, you should combine the steps above and cleanse the hot water heater on a regular basis. Flushing also provides an opportunity to inspect some of the components, such as the anode rod and drain valve. If the anode rod has been consumed and it is no longer performing as it should, it should be replaced.
How to flush a water heater with the hydrogen peroxide
- Electric water heaters should be turned off by turning the breaker box to the OFF position
- Gas water heaters should be turned off by simply turning the gas control valve pilot position
- And solar water heaters should be turned off by turning the breaker box to OFF position. Open the hot water tap and the TPR valve in the vicinity
- Drain enough water to make room for hydrogen peroxide or to bring the level of the TPR valve below the TPR valve. In case the water heater has a capacity of 40 gallons, add 1-2 pints of hydrogen peroxide (3 percent concentration). If the item is of a different size, adjust the amount to reflect this. Peroxide should be poured through the TPR valve, anode rod, or water exit if at all practical. Fill the tank with cold water by opening and closing the cold water inflow valve
- Allow the hydrogen peroxide to sit in the tank’s water for a few hours
- And Close the cold water valve and turn on the hot water faucet again to allow the hydrogen peroxide to flush through the supply lines. Pour out the whole contents of the tank (including any debris) and refill it with water. Drain the water by closing the drain valve. Fill the tank with water until it is completely full
- In order to remove any remaining stinky water or to ensure that the water is clean, repeat the flushing process via the pipes and drain it again if required. The tank should be filled with water (the drain valve is closed). With the hot water faucets open, remove any remaining air from the tank. In addition, utilize the pressure relief valve to drain the air from the system. Resuming the operation of the electrical and heating systems
Please keep in mind that vinegar (including apple cider vinegar) can also be used for flashing in quantities of one gallon or less. Because most water heaters come with the plastic drain valve pre-installed, dirt can block the valve and cause it to leak as a result of poor seating when the device is flushed during the cleaning process. It should be replaced with a ball valve. Get Quotes from Highly Qualified Water Heater Professionals! Get Free Estimates on Your Project!

Maintaining Your Tank Water Heater
Tank water heaters are not quite the simple tub of hot water that they appear to be on the surface of the picture. There is a lot of chemistry going on inside the shell, which makes sense. Leaving it unattended might result in your water heater failing before its time. However, by following a few easy maintenance guidelines, you should be able to keep your cabin flush with hot water for many years. Drain the tank with high-pressure water. Due to the fact that tank water heaters may operate as a storage facility for sediments, cleaning the tank on a regular basis can be quite beneficial in keeping the rust from corroding the tank from the inside out.
- Turn off the breaker for any electric heaters you have
- If you have a gas heater, turn it to the pilot setting. To turn off the water heater’s inlet valve, follow these steps: Open the bottom-of-the-tank drain, then open the pressure vent, and then allow gravity to drain the water through a hose to a convenient drainage point. This may take some time, and you may find that the water you drain is generally clear of silt after a while. That does not necessarily imply that there is no sediment on the bottom of the tank
- Sediment may have settled into a layer that is slightly compacted on the tank’s bottom as a result of the compacting. When using a gravity drain, it is typically difficult to remove this layer. In order to completely flush out the sediment from your tank, you must add a shock of fresh water to the largely empty tank after running the gravity drain described above. Leave the vent valve open, and then open the intake valve to let the air in. It is anticipated that cold water will flow into the empty tank, disturbing the sediment layer. Turn the inlet back on and re-drain the system as many times as necessary.
As needed, the sacrificial anode should be replaced. An ordinary tank water heater is nothing more or less than a metal tub that has been filled with water. When metal is exposed to water, we all know that it rusts. So how is it that we can purchase water heaters with 12-year warranties? After all, shouldn’t they have rusted out long before then? The answer is a special component in your heater called a “sacrificial anode,” which is described below. It is commonly composed of aluminum or magnesium and is screwed onto the top of your water heater (see your handbook for specific installation instructions).
- Sacrificial anodes corrode at varying speeds, depending on the chemistry of the water, the temperature of the tank, and other factors.
- Rather than aluminum, magnesium anodes are recommended by the majority of plumbers because magnesium is more effective and because these anodes are generally easier to replace.
- Sacrificial anodes are critical in keeping tanks from rusting, but they might have an unintended consequence: they can cause corrosion in the surrounding environment.
- If your hot water smells like rotten eggs, but your cold water is devoid of odors, it’s a strong probability that your water tank is inhabited by sulfate-reducing bacteria, which are generally considered to be innocuous.
- One of the most effective ways to get rid of germs is to add a pint of hydrogen peroxide for every 40 gallons of hot water in the system.
- The majority of tanks are odor-free within an hour of introducing the peroxide solution.
Considering replacing the sacrifice anode with a motorized anode when dealing with corrosive water. It is more costly, but it does not corrode, and it starves germs, so it does not produce a stinky odor when used. Thinkstock.com

Water Heater Cleaning Chemicals
There are a variety of difficulties that can arise with different types of accumulation inside the tank, regardless of the type of water heater you have. Mineral buildup caused by hard water is one issue, but bacteria may also grow on the interior of a water heater, causing it to malfunction. It is important to clean your tank on a regular basis to keep it in excellent condition, and different chemicals may be used to prevent both mineral accumulation and germs. The tank must first be turned off and drained, either completely or partially, before the chemicals can be added.
- There are a variety of difficulties that can arise with different types of accumulation within a water heater tank, regardless of the brand or model. Water heaters can acquire germs growing on the interior due to mineral buildup caused by hard water, which is one of the problems. Cleaning your tank regularly keeps it in excellent condition, and different chemicals may be used to battle both the issues of mineral accumulation and the problems caused by bacteria. The tank must first be turned off and drained, either completely or partially, before the chemicals can be added. After cleaning, the tank must be flushed to eliminate the chemicals.
- Vinegar is a mild acid that is safe to drink in small amounts. However, it is powerful enough to help your water heater by dissolving the mineral deposit that has accumulated inside. Drain the tank and then fill it with about one gallon of vinegar. Allow it to rest for approximately six hours before draining the vinegar and refilling the water tank. For a tankless water heater, you may apply a similar procedure, but instead of connecting the heater to the water supply, you will fill it with vinegar. Carrying out this maintenance procedure on a yearly basis is an excellent preventative precaution for your equipment, however you may need to repeat the procedure numerous times if you have a visible hard water problem.
- Most of the time, the stench of rotting eggs will alert you that bacteria has taken up residence in your aquarium. Fortunately, a common home chemical, hydrogen peroxide, may be used to eliminate harmful germs from the environment. An appropriate solution is to use regular diluted peroxide, which can be obtained at any drugstore. Drain some of the water from the heater to create place for a few pints of hydrogen peroxide, and then pour the peroxide into the heater to activate it. Peroxide is toxic to bacteria, which is why it is widely used to clean wounds. Peroxide is also effective against viruses. If you just use a few quarts at a time, you won’t have to flush the tank using this strategy, which saves you time. As a result, the peroxide will be dilute to the point where it is no longer toxic to consume
- Instead of using additional “home” chemicals, you can alternatively use a delimer, which is a product that is particularly created for cleaning water heaters and other similar appliances. These chemicals are often extremely acidic and potentially toxic, yet they are excellent in removing mineral buildup from the tank’s bottom. The procedure is the same as with the other methods: you drain the tank first, then add a gallon or two of the deliming chemical. While it is always a good idea to review the owner’s handbook for your heater when using any technique, it is especially critical while using this one. There may be a specific chemical or procedure that the manufacturer suggests for the best combination of safety and effectiveness. Additional considerations include the fact that some heaters include an anode at the bottom of the tank that should not be in touch with a deliming chemical.
Why does my hot water smell like rotten eggs? (Part 2 of 2)
In Part 1 of this piece, we discussed some of the factors that contribute to the rotten egg smell in your hot water. The topic of today’s discussion will be some of the remedies for this rotten predicament.
How do I get rid of a sulfur smell in my hot water?
It is technically possible to get rid of a sulfur smell from your hot water by either stopping the formation of hydrogen sulfide gas (H2S, which is the source of the smell, as you may recall from Part 1) or killing the bacteria that is causing it. However, this is not something you should do.Removing your anode rod is not a good idea. Removal of your anode rod will not only increase the pace of tank corrosion (which might result in a tank failure), but it will also void the warranty on your water heater!
Fixing a stinky hot water problem: Three solutions
Solution 1: Use hydrogen peroxide to eliminate the microorganisms. If you are familiar with the operation of a water heater, you might attempt this repair on your own. If you don’t know how to do it, call the water heater professionals at P. GagnonSon, and we’ll take care of everything for you.
- Close off the cold water inlet valve on your water heater
- And Discard around ten percent of the water stored in your hot water storage tank. Remove the metal line that connects to the cold water side of your water heater and set it aside. Pour in one cup (8 oz) of hydrogen peroxide for every 10 gallons of water your tank contains (four cups for a 40 gallon tank, for example), using 3 percent hydrogen peroxide (H2O2 — the stuff you can get at your local drug store for a $1)
- Reconnect the hose, turn on the cold water valve to refill your tank, and then let it sit for a couple of hours to let the water settle. The hydrogen peroxide will destroy the germs and, as a result, the odor will be eliminated.
Replace your anode rod with a zinc and aluminum type as a second option. Removal of the magnesium or aluminum anode from your water heater and replacement with a zinc and aluminum anode is another option for perhaps eliminating the rotten egg smell in your water heater – just make sure you obtain one that’s the same kind and size as your existing anode. You should be able to tell a change within a few days. Solution 3: Install a tankless propane water heater in lieu of your existing storage-type water heater.
Your water heater will provide you with infinite hot water while also saving you 30% or more on your water heating expenditures.

Thiscommon problemis a symptom of a more serious condition, which is fortunately straightforward to recognize and resolve. So, where does the rotten egg odor come from, and how can you get rid of it once and for all?
Why does my hot water have a sulfur smell?
Softened water can occasionally build hydrogen sulfide gas, which when released emits the odor associated with “rotten eggs.” A variety of factors might cause this odor to develop in cold water; however, when it occurs only in hot water, your hot water heater is the most likely source of the problem.
This component of your water heater is responsible for drawing corrosive substances from the water. Because of the corrosive action of the anode over time, the heater is mostly corrosion-free during this process. This can sometimes result in a reaction between the rod and the sulfate in the water, with the heated water becoming odoriferous as a result. Some heaters include more than one anode rod, and it is vital to inspect and replace them on a regular basis in order to maximize the tank’s longevity.
A naturally occurring bacterium in the water supply can thrive in your heater, resulting in an increase in the production of hydrogen sulfide fumes in the environment. The bacteria present in this situation must be eliminated in order to eliminate the odors emanating from the water heater in this situation.
How do I fix it?
With a few simple measures, you can get rid of the rotten egg odor completely. In the instance of a faulty anode rod, you will need to locate the damaged rod and replace it as quickly as possible. When it comes to germs, hydrogen peroxide is quite effective in cleaning the tank and preventing the bacteria from reproducing.
Diagnosing Your Anode Rod
As previously stated, the anode rod serves as a “sacrificial” component, attracting corrosive materials to the system. As a result, the guarantee period for most water heaters is directly proportional to the number of anodes present, with one rod providing up to 6 years of service (12 years for 2). Typically, a rod will be totally consumed within 4-5 years, while it may survive as long as 10 years or dissolve in as little as a couple of years, depending on the quality and consumption of the water in your home.
Your anode rod will require the use of the following instruments in order to be examined (and, if necessary, replaced).
- As previously stated, the anode rod serves as a “sacrificial” component, attracting corrosive substances to the electrode. Because of this, the guarantee on most water heaters is directly proportional to the amount of anodes present, with one rod providing up to 6 years of protection on average (12 years for 2). Typically, a rod will be totally consumed within 4-5 years, while it may survive as long as 10 years or dissolve in as little as a couple of years, depending on the quality and consumption of the water in your system. It’s important to know how old your water heater is if you’ve never changed the anode rod in it before. Having the following tools on hand will help you evaluate (and, if necessary, replace) your anode rod.
Make careful to switch off the electricity to your heater before beginning any work. This is the circuit breaker in your fuse box that is responsible for servicing the heater in the case of an electric heater. Instead of shutting off the gas altogether, you may merely turn the gas control valve down to the “vacation” level or the lowest setting instead of totally turning it off. The reason for this is because if a heating element comes into touch with air while in operation, it may be destroyed.
- While you may empty it into a bucket or down a drain, you should exercise caution while handling the hose since it will get quite hot throughout the draining process.
- It is often in the shape of a hexagonal plug and is usually located at the top of the tank, however it may occasionally be placed to the side of the tank.
- Turn off the drain valve after the water level has dropped to a safe level.
- A hot water faucet near the tank will be required to be turned on since there is now a vacuum in the tank.
- Use your socket wrench for this, and you may have to work the head a little bit to get it to loosen up enough.
It is possible that a healthy rod is too thick to be removed. Looking at the rod, you will be able to see how much corrosion has occurred, and a faulty anode will have been partially or completely eaten away.
Replacing an Anode Rod
You may want to explore replacing a defective anode rod with a different kind or substance of anode rod before replacing the entire anode rod assembly.
Non-Traditional Anode Rod Types
Flexible anodes are identical to standard anode rods, with the exception that they are capable of being bent. This makes it easy to change them when working in confined areas. Newer solutions, such as powered anode rods, generate electrical pulses that increase the efficiency of the rod’s anti-corrosive properties. Hot water outlet rods can also be purchased to increase the efficiency of an existing hot water outlet rod.
Anode Rod Metals
There are three primary metals that are utilized to make rods, and you may want to select the one that best meets your requirements from among them. Using Zincis, which is naturally anti-fungal, will assist to reduce the quantity of bacterial development in the aquarium. The best option if your water is often foul-smelling is to install a water filter. The most often used zinc rods are really a mixture of aluminum, tin, and zinc alloyed together. Rods made of magnesium are the most prevalent kind.
As an added bonus, the dissolved magnesium has a number of beneficial effects on the body.
Aluminum anode rods corrode at the slowest rate and are the most affordable.
Given their lower efficacy compared to magnesium rods, they are best employed when the rotten egg smell looks to be the product of a spent rod or when you intend to flush with hydrogen peroxide on a regular basis.
How to Add Hydrogen Peroxide to Your Water Heater
It is possible to eliminate anaerobic bacteria by doing a flush with 3 percent hydrogen peroxide.
- As previously said, turn off the electricity. Close the main shut-off valve and turn off the water. Start by turning on a nearby hot water faucet and the temperature and pressure relief (TPR) valve. Pour water into the tank until the water level is below the TPR valve, then turn off both valves. Toss in some 3 percent hydrogen peroxide (about 1-2 quarts per 40 gallons, depending on the size of your tank)
- And mix well. Continue to open the cold water input valve until the tank is completely full. Go ahead and turn off the valve and watch a movie
- Once the tank has been flushed, re-open the cold water valve and switch on the hot water tap (this will also treat your pipes). As you would typically do after flushing the toilet, let the tank to refill. If the water is hazy or stinks, repeat the flushing process. Restore electricity to your hot water tank after the hot water faucets are operating regularly.
