The unmistakable stench of sewer gas can be a cause for concern in any home. The pungent odor is not only unpleasant but may also indicate serious plumbing issues. Sewer gas is a health risk, so if you smell this rather nauseating odor, contact a professional as soon as possible. We have created an extensive guide to help you learn more about what sewer gas is, how to recognize its distinct smell, and what can cause it to enter your home.

What Is Sewage Gas?

Sewage gas is a mixture of gasses produced by decomposing organic matter in wastewater. This gas contains various compounds, including methane, ammonia, hydrogen sulfide, and carbon dioxide.

While it’s natural for sewer systems to produce these gasses, they should be contained within your plumbing system since they can be dangerous. However, sewage gas has a distinct smell that can’t be missed.

What Does Sewer Gas Smell Like?

The smell of sewer gas is often described as a noxious, rotten-egg-like odor. Its sulfuric, foul smell will permeate your entire home if left unaddressed, leading to major health issues down the line. Small amounts of sewer gas usually won’t cause any immediate danger—but large amounts certainly will.

Sewer Gas and Your Health

Sewer gas smells gross, no doubt. Although this gas can also pose health risks. Prolonged exposure to sewer gas can cause symptoms like headaches, nausea, dizziness, and irritation of the eyes and respiratory tract. Below are three types of gasses found in sewer gas along with how they can compromise your health:

Hydrogen Sulfide

This is the main type of gas found in sewer gas. It can be extremely toxic to humans and animals in large amounts, posing the risk of organ damage or even death.

Ammonia

High amounts of ammonia exposure can burn a person’s eyes, nose, throat, and even respiratory system. This type of exposure can lead to lung damage and can even be fatal.

Top 5 Causes of Sewer Gas Smells

Now that you know what sewer gas is, let’s look at what causes sewer gas to enter your home.

1. Water Traps

Water traps, also known as P-traps, are U-shaped piping sections designed to hold water and create a barrier between your living space and the sewer system.

Their unique shape is what helps block sewer gas from entering your home. If these traps dry out or become damaged, they no longer serve as an effective barrier and can allow sewer gas to enter your home through the drain.

2. Clean-Out Caps or Plugs Have Disappeared

Clean-out caps or plugs are an important part of your plumbing system. These caps provide access to your plumbing lines. So if these caps or plugs are missing or loose, sewer gas can escape and cause sewer gas to enter your property.

3. Ineffective Toilet Wax Ring

The wax ring beneath your toilet acts as a seal, preventing sewer gas from seeping into your bathroom. If this ring is damaged or improperly fastened, it can compromise the seal and allow odors to enter your living space. If this is the case, simply replace the seal yourself or call an expert to do it for you.

4. Sewer Line Leaks

A sewer line leak is a serious issue. Cracks or breaks in your sewer line can lead to leaks, allowing sewer gas to permeate the surrounding area. The gas can even enter the soil around your home. If your toilet is making strange sounds in addition to the presence of foul smells, you likely have a sewer line leak.

5. Loose Plumbing Connections

Over time, plumbing connections can loosen due to natural wear and tear. If these connections become too loose, they could create a gap, allowing the smell of sewer gas to enter your living space. Regular inspections and maintenance can help prevent this, so be sure to contact a professional to receive support.

Ways to Eliminate Sewer Gas Odors in Your Home

You have just discovered sewer gas in your home. Now what? Whatever you do, don’t panic. The first step you should take is to call an expert plumber. There are also a few steps you can take to prevent sewer gas from creeping back into your space.

Make Sure Your Plumbing Traps Are Filled With Water

There should always be a little water in your traps. If you notice a methane gas smell on your property, check the P-trap to ensure it has water in it. This is a small but effective step in preventing sewer gas issues.

Clean Your Drains

The buildup of debris in your drains can contribute to unpleasant odors. Clean your drains regularly with a mixture of baking soda and vinegar followed by hot (not boiling) water to break down and flush away any accumulated grime.

Keep the Vent Stack Clear

Yes, your roof plays a part in your plumbing system too. The vent stack on your roof allows any gasses to vent away from your home. Make sure this stack is free from obstructions, such as leaves and other debris.
