Understanding Sewer Gas in Your Home

Sewer gas is a mixture of toxic and non-toxic gases produced by decomposing organic matter in your sewage system. The distinctive rotten egg smell is caused by hydrogen sulfide, but sewer gas can also contain ammonia and methane—both of which can be harmful to your health and even flammable.

The P-trap is a U-shaped pipe under your sink that holds water to create a barrier against sewer gases. If a sink, shower, or floor drain isn't used for a while, the water evaporates, allowing sewer gas to enter your home.

Vent pipes allow air into your plumbing system to maintain proper pressure. When blocked by debris, leaves, or bird nests, sewer gas can be forced back into your home through drains.

Over time, seals around drainpipes, toilets, and connections can deteriorate or loosen, creating gaps where sewer gas can escape into your living spaces.

Cracks, breaks, or deterioration in your sewer line can allow sewer gas to seep into your basement or crawl space, creating persistent odor problems.

The wax ring seal at the base of your toilet can dry out or become damaged, allowing sewer gas to escape around the toilet base—a common source of bathroom odors.

The overflow hole in bathroom sinks can harbor bacteria and debris, producing foul odors. This small opening is often overlooked but can be a significant source of smell.

Health Risks of Sewer Gas Exposure

Sewer gas exposure isn't just unpleasant—it can pose serious health risks to you and your family:

  • Respiratory Problems: Prolonged exposure to sewer gas can cause breathing difficulties, coughing, and throat irritation. People with asthma or respiratory conditions are especially vulnerable.
  • Nausea and Dizziness: High levels of hydrogen sulfide can cause headaches, nausea, dizziness, and fatigue. These symptoms often worsen with continued exposure.
  • Fire Hazard: Methane, a component of sewer gas, is highly flammable. In enclosed spaces with poor ventilation, methane can accumulate and create an explosion risk.
  • Severe Neurological Effects: In extreme cases, prolonged exposure to high concentrations can lead to memory loss, loss of coordination, and even asphyxiation.
  • Eye Irritation: Sewer gas can cause redness, watering, and burning sensations in the eyes, particularly in poorly ventilated areas.

Prevention: How to Keep Sewer Smells Away

Once we've solved your sewer smell problem, follow these tips to prevent future issues:

  • Run Water Regularly: If you have seldom-used sinks, showers, or floor drains, run water for 2-3 minutes every few weeks to keep P-traps filled.
  • Schedule Annual Inspections: Have your plumbing system professionally inspected once a year to catch small problems before they become major issues.
  • Clean Drains Monthly: Use enzyme-based drain cleaners monthly to prevent buildup and keep drains flowing smoothly. Avoid harsh chemical cleaners that can damage pipes.
  • Check Vent Pipes: Have your roof vent pipes inspected regularly to ensure they're not blocked by debris, leaves, or animal nests.
  • Maintain Toilet Seals: Check around toilet bases for water or looseness. Replace wax rings every 5-7 years or when you notice problems.
  • Install P-trap Primers: For floor drains that dry out frequently, consider installing automatic P-trap primers that add water periodically.

Frequently Asked Questions About Sewer Smells

Sewer gas has a distinctive rotten egg smell caused by hydrogen sulfide. It can also have an ammonia-like odor or smell musty and unpleasant. The smell is usually strongest near drains, toilets, or in basements.

Yes, sewer gas can be harmful, especially with prolonged exposure. It can cause respiratory problems, headaches, nausea, and dizziness. High concentrations can be toxic. Additionally, methane in sewer gas is flammable and poses an explosion risk in enclosed spaces.

Rain can overwhelm your sewer system and force gases back through floor drains or compromised seals. It can also indicate a problem with your roof vent pipe, which may be partially blocked and allowing pressure changes during storms.

Simply run water in the affected drain for 2-3 minutes to refill the P-trap. For seldom-used drains, pour a cup of cooking oil down the drain after running water—the oil floats on top and slows evaporation.

Absolutely. Vent pipes allow air circulation in your plumbing system. When blocked, negative pressure can suck water out of P-traps or force sewer gas back through drains. You may also hear gurgling sounds when water drains.

Kitchen sink odors usually come from food particles trapped in the drain, garbage disposal, or a dry P-trap. Bacteria decompose the organic matter, producing hydrogen sulfide gas. Clean your disposal regularly and run water to keep the P-trap filled.

Costs vary depending on the cause. Simple fixes like refilling P-traps or replacing wax rings are inexpensive. More complex repairs like sewer line repairs or vent pipe clearing may cost more. We provide free estimates and transparent pricing.
