Why Does My Water Heater Smell Like Rotten Eggs?

If you’ve ever turned on your faucet only to be greeted by the awful scent of sulfur, you might wonder, “Why does my water heater smell like rotten eggs?” There are many reasons why your water heater might start to stink, and it’s important to understand the underlying issue so you know what actions to take. 

In this blog post, the expert plumbers at S & D Plumbing discuss what causes rotten egg odors in water heaters and what you can do to resolve the problem so you can regain safe, reliable functionality for your system. 

Where Does the Rotten Egg Smell Come From? 

One of the most common culprits behind an unpleasant rotten egg odor in your water heater is hydrogen sulfide gas.

This gas can occur naturally in groundwater and is often present in wells or areas with high mineral content in the water. When this hydrogen sulfide mixes with the hot water in your heater, it can create that distinct rotten egg smell that wafts from your faucets and fixtures whenever you run the tap. 

What Causes My Water Heater To Smell? 

Now that you understand where the rotten egg odor comes from, let’s unpack how this process unfolds within your water heater. Essentially, a chemical reaction takes place inside your system involving water, certain types of bacteria, and the sacrificial anode rod within your water heater.

This rod is typically made of either magnesium or aluminum and is designed to attract corrosive elements in the water, protecting the tank from rust and corrosion. 

However, in environments where bacteria thrive, such as those with high sulfur content, these microorganisms can interact with the rod, producing hydrogen sulfide gas. Over time, this gas builds up and becomes noticeable when using hot water, leading to that unpleasant rotten egg odor. 

How To Fix a Smelly Water Heater 

So, how can you fix the sulfuric smell from your water heater? The answer is relatively straightforward. Replacing the sacrificial anode rod in your water heater with an aluminum or zinc alloy rod can effectively eliminate the conditions that foster bacterial growth and hydrogen sulfide production.

It’s essential to consult with a professional plumber to ensure the correct type of rod is selected and installed. At S & D Plumbing, we understand the importance of a smoothly functioning water heater and its impact on daily life.
