Four Reasons Why Your Water Heater Smells Like Rotten Eggs in Bloomfield, IN

Having odd odors in your home can be frustrating, especially if you can’t track down the cause. When your water heater smells like rotten eggs, a few different issues could be to blame. 

You can trust our experts for water heater and heating repair in Bloomfield, IN, to fix the problem quickly. Learn more about the source of this odor and some steps we can take to alleviate it.

1. Bacteria Are Collecting in the Tank

When sulfate bacteria are in the tank, they feed on sulfates in the water. Through this process, the bacteria create hydrogen sulfide gas, which leads to the rotten egg smell. 

These bacteria thrive in areas that don’t have easy access to oxygen, like a full water heater tank or a plumbing system. 

2. Your Magnesium Anode Rod Is Failing

A traditional water heater has an anode rod inside that protects the tank from rust. Rust particles in the water are drawn to the anode rod, which may consist of magnesium.

If you use a water softener, you could experience a sulfur odor. The salt from the softener may interact with the magnesium in the anode rod, creating sulfate gas. 

When your water heater smells like rotten eggs, you’ll notice the odor when opening faucets and using warm water. If you have an anode rod problem, you might also have air escaping out of the faucet along with the water.

3. Reduced or No Usage of Hot Water

When you have stagnant water in the appliance because you’re on an extended vacation, bacteria have a chance to build. If these bacteria start feeding on the sulfates, you could end up with a rotten egg odor.

4. Poor Quality of Water Supply

A water heater that smells like rotten eggs might be due to the quality of your water supply. Failing to filter for sulfates can lead to high levels in the tank, giving the bacteria a chance to thrive.

Ways to Fix It When a Water Heater Smells Like Rotten Eggs in Bloomfield, IN

You can take several steps to try to alleviate the sulfur odor you’re receiving from the tank, but certain tasks will require the help of our plumbers. 

Treat the Water

If you have high levels of sulfates in your supply, you can have our plumbers install a filtration system that removes these contaminants. To install the correct type of filtering system, our plumbers will test the water supply and determine what exactly you need to solve the odor issue.

Our team can also use a shock chlorination treatment that disinfects the tank and removes any buildup of bacteria. Without the bacteria creating sulfur gas, you should notice reduced odors.

Replace the Anode Rod

When a water heater smells like rotten eggs, we can often fix it by replacing the magnesium anode rod inside the tank. Rather than using a magnesium rod, we might switch to an aluminum or zinc rod that won’t interact with the salt from the softener.

Increase the Temperature Setting

If you want to make it more difficult for bacteria to form inside the tank, consider increasing the temperature, as bacteria like warm conditions better than hot ones. Use a temperature setting between 125 and 130 degrees for the greatest level of effectiveness while reducing the risk of scalding.

Turn Off the Appliance During Vacations

If you are leaving the house for a few weeks and no one will be using hot water, you might want to shut off the appliance. Bacteria enjoy warm conditions inside the tank, but if the appliance is not generating any heat and the temperature is cold inside the tank, bacteria will not thrive.

Install a New Appliance

You might want to try a tankless model that prevents stagnant water from becoming a problem. Our technicians can provide advice on selecting new water heaters.
