Sulfur Smell In Your Hot Water? Here’s 4 Amazing Ways To Fix It.

Sulfur Smell Within Water Heaters is a Widespread Issue

Sulfur smell in hot water

Plumbing and water treatment companies are often faced with complaints pertaining to bad odors emanating from the water heaters. These unpleasant smells are commonly compared to that of rotten eggs. The odor issues can cause numerous problems for the inhabitants, and often becomes a topic of conversation when guests are around. Today, we present the optimal, most efficient, method to get rid of this Sulfur smell.

What Are The Causes of This Sulfur Smell?

First and foremost, it is worth noting that the sulfur smell in water can be caused by a number of different “reactions”.

If the odor is present in both cold water and hot water, the problem usually stems from the presence of sulphate-reducing bacteria in your water. It can also be a sign of the presence of hydrogen sulphide gas in the water underground. To determine the cause of these odors, just let the water run for a longer period. If the odor is less pungent after a few minutes, it is usually indicative of a sulphate-reducing bacterium.

Finally, if the odor is present only in your hot water, it is usually created by a chemical reaction in your hot water tank. Now that you know the causes of these nauseating smells, let’s solve the problem!

Here Are The Best Ways to Stop The Sulfur Smell

Preventing the Development of Sulphate-Reducing Bacterium 

Temporary Solution: Concentrated Chlorination Treatment 

Generally seen living in a low-oxygen environment such as water heaters, deep wells, as well as in the plumbing network, these bacteria take their energy from sulfur. Since they usually proliferate in hot water, it is standard for the rotten egg smell to amplify when faced with these environments.

A temporary solution would be to do a concentrated chlorination treatment, which involves adding a predetermined amount of chlorine to your well and circulating the water through all your ducts. Once the smell of chlorine is noticeable throughout your home, simply let the water run until the smell disappears. However, it is not recommended to use or consume this water for 24 hours after treatment, which makes this solution much less convenient. In addition, since this is a temporary solution, keep in mind that odors will be back in 2 or 3 months.

Permanent Solution: Imposed Current Anode

If you desire a more permanent solution, the current anodes limit the proliferation of bacteria in your hot water tank, which has the effect of eliminating odors. By lowering the pH of the water in your tank, the imposed current anodes make the environment less optimal for the survival of the bacteria. In addition to only requiring a few minutes to install, CORRO-PROTEC anodes are guaranteed for 20 years and we even offer a 90-day satisfaction guarantee.

Rectifying This Reaction Within Your Water Heater 

Each water heater is equipped with a magnesium anode rod in order to temporarily limit corrosion within the tank. In most cases, the smell of sulfur will be caused by high magnesium content water that comes into contact with the original anode already present within the water heater. If the odor issue comes from the reaction between the magnesium anode and your water, several options are available to you. However, it is important to know that these options are not all good in the long run.

Remove Magnesium Anode (NOT RECOMMENDED) 

It would be possible to eliminate these odors by completely removing the magnesium anode from the tank. However, doing so is very dangerous for the water heater because it will then be without its protection against rust. The weakest and most exposed places will then rust faster forcing you to change your tank after only a few years.

Replace the Magnesium Anode With an Aluminum Anode 

It is also possible to replace the magnesium with an aluminum anode. Water will no longer have a poor chemical reaction while supported by the new anode, and odors should completely disappear. However, even though aluminum anodes are cheaper than magnesium anodes and last longer, the main issue is that as the anode dissolves, debris tends to harden and sink to the bottom of the reservoir. This can potentially end up in your faucets and cause breakage. In addition, some scientific research raises concern regarding aluminum residues found in water which could have adverse effects on people’s health.

Install an Imposed Current Anode 

In conclusion, an imposed current anode is the ideal solution to these problems, because in addition to eliminating this rotten egg smell in a few hours, these anodes are made from insoluble titanium, which limits their debris. In addition, this technology requires no maintenance and is good for several years. CORRO-PROTEC anodes are easy to install in your existing tank and will fix the problem, no matter what the cause of the odors, in just a few hours. You are skeptical? We offer a 90-day money back guarantee if you are not satisfied with the product’s performance. 

Our house was having the “rotten egg” smell in our hot water for some time after putting in a new hot water heater 9 months prior. After several attempts to shock our water and asking around for suggestions, we took to the internet and found this Corro-Protec Anode on a YouTube demonstration. Best $100.00 we have ever spent. Anode rod was easy to install and smell was 90% gone immediately. Was completely gone by my morning shower so I was happy!!!

    Couldn’t believe it but this product took care of our sulfur smell in hot water couple minutes after installation!!! Thank you sooooo much !

  2. Sandy on February 7, 2020 at 9:52 pm

    Can you help me locate the anode rod on the Rheem XE50T10HD50U1?

  3. Nikki on February 4, 2020 at 10:32 pm

    Does this work if you have a salt water softening system?

    • Corro-Protec on February 5, 2020 at 11:17 am

      Hello Nikki,

      Yes, it’s working with a salt water softener!

      Regards,
      Vincent

    • Pat on February 25, 2020 at 10:44 pm

      We have a water softener and it took care of the smelly water immediately

  4. Drew on January 29, 2020 at 5:14 pm

    I have a 38 gallon water heater is there a certain size anode I need to buy?

  5. Stephanie Warner on January 27, 2020 at 8:01 pm

    Hi
    We have a bad smell in our laundry which has the hot water cylinder in it. The smell varies in strength but seems worse in the mornings when we are using the hot water most often. There doesn’t appear to be any smell coming from the water out of the taps though. Any ideas?

    • Corro-Protec on January 30, 2020 at 9:13 am

      Hello,

      If you have smell coming from only one specific place, the cause of the smell is somewhere in the fixtures or pipes supplying this specific faucet.

      Regards,
      Vincent

    Just installed mine a wk ago was pretty sceptical of it working but so far it has worked exactly as promised!! Worth the money!!

  7. Tare Delaney on November 10, 2019 at 9:54 am

    when you bath in that water when it has a bad smell odor real loud would it harm your body or your lungs or make you sick smelling it

    • Corro-Protec on November 11, 2019 at 8:14 am

      Hello Tare,

      We are specialized in cathodic protection and unfortunately we can not answer medical questions. The different scents in hot water can come from various sources, if in doubt, you should have your water analyzed by experts in water treatment.

      Thanks,

      Vincent

    I don’t have any odor in my cold water. I still have sulphur odor in my hot water after removing the anode. Will this product still remove the smell?

    • Corro-Protec on November 5, 2019 at 2:24 pm

      Hello Tom,

      Yes, our Corro-Protec powered anode rod will take care of that sulfur smell in your hot water!

    I dont have an anode rod in my electric water heater, how can i install this rod?

  10. Mike wallace on October 6, 2019 at 8:27 am

    How long is the rod, have limited space above water heater.

    • Corro-Protec on October 7, 2019 at 2:02 pm

      Our Corro-Protec Anode is 12 inches long!

  11. Matt B on September 14, 2019 at 2:22 pm

    We have a tankless water heater and seem to be having smell issue with our hot water. Our old heater had a tank and had the same odor problem. Is this recurring smell caused by the same problem?

    • Corro-Protec on September 16, 2019 at 8:05 am

      It is very rare to have this smell with a tankless water heater, we would like to know more about it, we sent you an email from info@corroprotec.com

      • John on November 25, 2019 at 9:46 pm

        I have this same issue…tankless water heater, but we get a few seconds of rotten egg smell when using the hot water.

  12. Steven on June 4, 2019 at 9:03 pm

    We live in a motor home park. Other people here have the same thing. We all live in the northern Salem and the water come from the river.

  13. Jason on May 29, 2019 at 10:54 pm

    I have a unit on our 55 gallon tank and love it. Fixed our rotten egg smell quickly. I am curious how the power supply works. Is it a current-limiting supply, or is the current a result of the 24V applied potential and some internal resistance in the anode rod? I ask because our supply went out and wondered if I could use a non-current limited higher wattage 24V supply as a replacement.

    • Corro-Protec on May 31, 2019 at 5:37 pm

      Hello Jason, you can’t use non-current limited power supply for your Corro-Protec Anode. To ensure you have optimal protection, you need to use our Corro-Protec Rectifier. Please contact-us if you have any problems at info@corroprotec.com

      Thank you,

    I had fixed my odor problem with an aluminum rod a few years ago, but I have hard water issues, and its led me to replace the anode too often. We are happy to have found a long term solution

    • Anna Beard on May 16, 2019 at 5:41 pm

      Exactly how did you fix the odors with an aluminium rod?

      • Corro-Protec on May 16, 2019 at 5:48 pm

        The aluminum anode does not really eliminate odors.

        By removing the magnesium anode already present in your tank, the chemical reaction between the magnesium anode and your hot water will no longer continue and the odors should stop. We tell customer to replace the magnesium anode with a aluminium or a titanium anode because It is very important to have protection against corrosion in your water heater! Take note that the magnesium anode is not the only factor that can create odors. Powered titanium anode is the ultimate solution to cancel all rotten egg smell in hot water.

  16. Arnold on February 20, 2019 at 10:21 am

    We also have odor problems, but they are present in cold water and in hot water. However, it looks like it’s amplified in hot water.
    Could an anode like yours solve this problem?

    • Corro-Protec on February 27, 2019 at 1:31 pm

      Yes, the smell in your hot water will no longer be amplified.

      • Phil Miller on February 2, 2020 at 10:05 am

        What about the cold water smell?

        • Corro-Protec on February 4, 2020 at 7:49 am

          Our Powered Anode only stop the smell in hot water!

  17. Mark on February 9, 2019 at 11:49 pm

    Interesting! My neighbor advised me to simply remove the magnesium anode… I will continue my research because it doesn’t seem to be a very good advice from him. Does your product work every time for water odors?

    • Corro-Protec on February 11, 2019 at 9:10 am

      Yes it will! If not, we have a 90 Day Money Back Guarantee!

    • Bonnie Casto on September 20, 2019 at 5:06 pm

      We have stinky bad rotten egg smell in our got water, we installed a new hot water tank 2 weeks ago , how can we fix please any info will help me ??????

  18. John Rickwood on February 2, 2019 at 11:22 am

    Thanks! No more smell in our hot water few hours after the installation.

    • Kim & Steve on January 20, 2020 at 11:27 am

      Hello. We are having an issue with smelly water from a hot water faucet. However it’s only from one water source in our home, in our bathroom sink. The tub kitchen and other sources I’m our home have no issues with odour. Can someone advise.

      • Corro-Protec on January 20, 2020 at 12:25 pm

        Hello,

        If you have smell coming from only one specific faucet, the cause of the smell is somewhere in the fixtures or pipes supplying this specific faucet.

        Regards,
        Vincent

        • Scott R. on January 31, 2020 at 11:52 pm

          OK, I get that the smell is coming from the fixture or the pipes serving that fixture, but what could be the cause when you have an isolated condition like this?

          • Corro-Protec on February 6, 2020 at 11:10 am

            It could be caused by bacteria that have grown in a pipe, part of a pipe or vent that is blocked, or due to a leak. We recommend that you do business with a plumber to find a permanent solution to this problem.
