Smell Sewer Gas in Your Home? Have You Noticed the Smell of Rotten Eggs or Sewer Gas?
If you smell sewer gas in your home, that unmistakable foul odor could be more than just an unpleasant nuisance—it’s often a sign of a larger problem with your plumbing. Below, we’ll explain what sewer gas is, what might cause you to smell sewer gas indoors, and how to handle it safely.
What is Sewer Gas?
Sewer gas is a byproduct of decomposing human waste, made up of gases like hydrogen sulfide, ammonia, and methane. While it’s not usually harmful at low levels, prolonged exposure or higher concentrations can lead to health issues like hydrogen sulfide poisoning. That’s why you should never ignore it when you smell sewer gas inside.
Is Sewer Gas Harmful?
In small amounts, sewer gas might not cause immediate harm. However, long-term exposure or breathing in high levels can lead to symptoms such as:
- Fatigue
- Headaches
- Nausea or vomiting
- Dizziness or confusion
In rare, extreme cases, exposure can result in more severe symptoms like seizures or even death. If you smell sewer gas persistently, it’s essential to get it checked out quickly.

What Could Be Causing You to Smell Sewer Gas?
There are several potential reasons you could smell sewer gas in your home. Here are the most common ones:
1. Water Leaks
Leaks in your plumbing system, either from poorly placed pipes or vents, can allow sewer gas to enter your home. Nearby septic systems with cracks in the foundation may also leak gas inside.
2. Cracked or Broken Pipes
Your pipes are supposed to keep harmful gases contained. If a pipe is cracked or broken, sewer gas can seep into your home and may even lead to a sewage backup if left unaddressed.
3. Blocked Air Vents
Air vents are designed to push toxic gases out of your home. If these vents become blocked with debris or dirt, sewer gas can build up in your pipes and leak into your living space.
4. Clogged Drains
A clogged drain can cause waste to back up, and if untreated, this can lead to the accumulation of sewer gas, which then escapes into your home. Learn why you should avoid DIY drain cleaning and let a professional handle stubborn clogs safely.
5. Dry Plumbing
When plumbing fixtures like drains or toilets aren’t used often, they can dry out. Water is essential to create a barrier that prevents sewer gas from entering your home. Without that barrier, gas can escape through your pipes.
6. Loose Toilets
A loose toilet that isn’t tightly sealed to the sewer line can leave a gap for gas to escape. Proper routine maintenance and a properly fitted toilet are key to preventing leaks.
What to Do if You Smell Sewer Gas and Suspect Exposure
If you start to smell sewer gas, pay attention to how you feel. Common symptoms of exposure include fatigue, headaches, nausea, and difficulty concentrating.
In rare cases of high-level exposure, you might lose your sense of smell, develop throat or lung irritation, or experience more severe conditions like seizures or a coma. Immediate action is needed if you’re experiencing any of these symptoms in your home.
