What is sewer gas?
Decaying drain waste can create a mixture of unfriendly, poisonous gases. Highly toxic gases can include hydrogen sulfide which smells like rotten eggs, ammonia, methane which can act like deadly carbon monoxide, carbon dioxide and nitrous oxides.
Symptoms for low level exposure can be eye irritation, breathing problems, headache, dizziness, nausea, or drowsiness. Exposure to high concentrations can affect your sense of smell. Extreme levels of hydrogen sulfide or methane can cause death or loss of consciousness.
And don’t forget that sewer gases can be highly explosive and flammable. Avoid creating a spark from a match, lighter or electrical ignition.
I smell sewer gas.
Sewer gas enters a home or business from a drain, a blocked or cracked roof drain vent, even from cracks in the foundation if gases are in the soil.
Try following the odor to locate the source of gas. You can help avoid sewer gas exposure by adding water to unused drains, floor drains and check roof plumbing drain vent blockage from bird or animal nests or leaves. If by chance the problem is behind a wall, you may want to hire a licensed plumber. PDM Plumbing can help remove dangerous sewer gas odors. Call 815-207-4111 for free advice.
