If you have ever noticed a rotten egg smell coming from your bathroom, basement, or kitchen, you may have wondered, can sewer gas make you sick? The short answer is yes. Sewer gas exposure inside your home can lead to headaches, dizziness, respiratory irritation, nausea, and other health problems depending on the concentrations and length of exposure.
For homeowners in Washington, sewer gas issues are more common than many people realize. Older plumbing systems, damaged pipes, clogged drains, and hidden sewer leak problems can allow harmful gases to enter your living space. Ignoring the smell sewer gas creates is never a good idea because it may indicate a serious plumbing or sewer system issue that requires professional attention.
At Barney’s Plumbing & Sewer Services, we help homeowners across Washington identify sewer gas leaks, repair damaged plumbing systems, and restore safe indoor air conditions before the problem becomes dangerous.
What Is Sewer Gas and Why Is It Dangerous?
Sewer gas is a mixture of gases produced by waste decomposition inside your sewer system. It can enter your home through damaged pipes, dry drain traps, cracked vents, or hidden plumbing leaks.
Some of the common gases found in sewer gas include:
- Hydrogen sulfide
- Methane
- Ammonia
- Carbon dioxide
- Sulfur dioxide
Hydrogen sulfide gas is the main reason sewer gas smells like rotten eggs. Even at lower concentrations, sulfide gas can create unpleasant odors and health discomfort. At high levels, gas toxicity becomes more dangerous and can affect breathing, nervous system function, and overall health.
In severe cases, sewer gas poisoning may lead to:
- Respiratory irritation
- Severe dizziness
- Eye irritation
- Nausea and vomiting
- Fatigue
- Headaches
- Difficulty breathing
- Can cause unconsciousness in enclosed spaces
- Rarely, prolonged exposure at extreme concentrations may contribute to death
Many homeowners assume a bad odor is harmless, but ongoing gas exposure inside a home should always be taken seriously.
Can Sewer Gas Make You Sick in Washington Homes?
Yes, can sewer gas make you sick is a very real concern, especially in homes with aging plumbing systems or hidden sewer leak issues. Washington properties often experience moisture related plumbing wear due to rainy weather and shifting ground conditions. Over time, this can damage sewer pipes and vent systems.
The risk becomes higher when:
- Plumbing traps dry out
- Sewer pipes crack underground
- Vent stacks become blocked
- Toilets lose proper seals
- Basement drains remain unused
- Sewer backups occur
When sewer gas builds up indoors, the air quality inside your home can decline quickly. Even mild sewer gas exposure may trigger symptoms in children, older adults, and people with respiratory conditions.
If you consistently smell sewer gas inside your home, do not ignore it. The odor itself is a warning sign that your plumbing system needs inspection.
Common Causes of Sewer Gas Leaks
Broken or Cracked Sewer Pipes
Damaged underground pipes are one of the leading causes of sewer gas leaks. Tree roots, corrosion, shifting soil, and aging pipes can all create cracks that allow gas to escape.
A sewer leak may also allow wastewater contamination near your property, increasing both plumbing and public health concerns.
Dry P-Traps
Every sink, shower, and floor drain contains a curved pipe called a P-trap. This trap holds water that blocks sewer gas from entering your home.
If a drain goes unused for a long time, the water evaporates and leaves an open pathway for gas smell problems.
Blocked Plumbing Vent Pipes
Vent pipes regulate air pressure inside your plumbing system. When vents become clogged with debris, leaves, or animal nests, sewer gas may push back into your home through drains.
Loose Toilet Seals
Toilets use wax rings to create airtight seals. If the seal weakens or shifts, sewer gas can leak around the toilet base.
Damaged Drain Lines
Kitchen and bathroom drain pipes can develop small leaks behind walls or under floors. These hidden plumbing problems often create a persistent sewer gas smell before visible water damage appears.
Signs You May Have Sewer Gas Exposure
What are the signs of sewer gas exposure?
Knowing the symptoms early can help protect your health and prevent expensive plumbing damage.
Common warning signs include:
- Rotten egg odor indoors
- Persistent gas smell near drains
- Dizziness or headaches
- Nausea
- Fatigue
- Respiratory irritation
- Burning eyes
- Increased symptoms when indoors
- Bubbling drains or toilets
- Slow drainage
- Gurgling plumbing sounds
If multiple people in your home experience symptoms that improve after leaving the house, sewer gas exposure could be a contributing factor.
Children and pets may react even faster to poor indoor air quality caused by sewer gas leaks.
How Sewer Gas Affects Indoor Air Quality
Many homeowners focus on mold or dust when thinking about indoor air problems, but sewer gas can affect your air quality just as seriously.
Hydrogen sulfide and methane gases may accumulate in enclosed spaces with poor ventilation. Over time, prolonged gas exposure may irritate the respiratory system and create chronic discomfort.
Low concentrations may only produce odor and mild symptoms. Higher concentrations increase health risks and require immediate action.
Indoor sewer gas problems can become worse during winter months when windows stay closed and ventilation decreases.
Why You Should Never Ignore a Sewer Gas Smell
A sewer gas smell is not simply an unpleasant odor. It is often a warning that your plumbing system has failed somewhere.
Ignoring the issue can lead to:
- Structural pipe damage
- Indoor contamination
- Mold growth from hidden leaks
- Higher repair costs
- Increased gas exposure
- Health risks for your family
- Fire hazards from methane buildup in rare cases
The longer a sewer leak remains untreated, the greater the chance of widespread plumbing repair needs.
Professional plumbers can identify whether the problem comes from venting, damaged pipes, blocked drains, or sewer line failure.
Professional Sewer Gas Inspection and Repair Process
At Barney’s Plumbing & Sewer Services, we use modern diagnostic methods to locate sewer gas leaks accurately and efficiently.

Depending on the issue, repairs may include:
