Why Your Water Smells Like Rotten Eggs and How to Fix It
Home /
If you’ve ever turned on your faucet and noticed a strong sulfur odor, you may have asked yourself why your water smells like rotten eggs. This unpleasant smell is usually a sign of sulfur bacteria or hydrogen sulfide gas in your plumbing system or water supply. At Clog Heroes, we help homeowners in Fredericksburg, VA tackle this issue so their homes can stay safe, healthy, and odor-free. Understanding the cause is the first step toward fixing the problem.
What Causes Water to Smell Like Rotten Eggs?
When water smells like rotten eggs, the most common culprit is hydrogen sulfide gas. This gas is produced when sulfur bacteria break down organic matter in your plumbing or water source. Even a small amount can create a strong odor, making it hard to ignore. The smell might be noticeable from both hot and cold taps, or sometimes only when using hot water, which helps pinpoint the source of the issue.
Is Water That Smells Like Rotten Eggs Dangerous?
The smell itself is unpleasant, but it doesn’t always mean your water is unsafe. In low concentrations, hydrogen sulfide is generally not harmful, though it can affect taste and make water less desirable for drinking or cooking. However, in higher concentrations, hydrogen sulfide can corrode pipes and fixtures, damage appliances, and sometimes pose health risks. If your water smells like rotten eggs, it’s important to get it tested to know exactly what you’re dealing with.
Common Reasons Water Smells Like Rotten Eggs
Several factors can cause sulfur odors in your water:
Bacteria in the Water Heater – Warm environments like water heaters provide the perfect conditions for sulfur bacteria to grow, releasing the rotten egg smell when hot water is used.
Groundwater Contamination – Wells in Fredericksburg and surrounding areas may naturally contain sulfur due to organic matter underground.
Plumbing System Issues – If the odor only appears in certain faucets, the problem may be isolated to those pipes or fixtures.
Corroded Anode Rods – Many water heaters contain a magnesium anode rod that reacts with bacteria and produces hydrogen sulfide gas.
Why Hot Water Often Smells Worse
If your water smells like rotten eggs only when you run hot water, your water heater is likely the problem. The heater’s anode rod can react with bacteria, intensifying the odor. Flushing the heater or replacing the anode rod often helps. In some cases, installing an aluminum/zinc rod instead of magnesium can eliminate the reaction that causes the smell.
How to Fix Water That Smells Like Rotten Eggs
Thankfully, there are several ways to eliminate the odor, depending on the source:
Flush and Disinfect the Water Heater – Draining the tank and cleaning it with a disinfecting solution can kill bacteria and remove odor.
Replace the Anode Rod – Switching to a different type of rod often reduces sulfur reactions.
Shock Chlorination for Wells – If the problem originates in well water, treating the system with chlorine can kill sulfur bacteria.
Install Water Treatment Systems – Carbon filters, aeration systems, or oxidizing filters can remove hydrogen sulfide and improve overall water quality.
Professional Plumbing Inspection – Sometimes the smell is linked to decaying organic material or buildup in your pipes, requiring professional cleaning.
Do-It-Yourself vs. Professional Solutions
Some fixes, like flushing a water heater, can be attempted by handy homeowners. However, sulfur odors often point to underlying problems that require professional tools and testing. If your water smells like rotten eggs throughout the whole house or comes from both hot and cold taps, it’s best to contact a plumber. At Clog Heroes, we use professional testing to identify the exact cause and provide long-term solutions instead of temporary fixes.
Preventing Water From Smelling Like Rotten Eggs
Once the odor is removed, you’ll want to prevent it from coming back. Regular water heater maintenance, annual well inspections, and routine plumbing checkups are effective ways to keep sulfur bacteria under control. For Fredericksburg homes with well water, installing a treatment system designed for hydrogen sulfide is one of the best preventative measures.
