Which plumbing issue can methane from sewer gas create?

Methane from sewer gas can create significant health hazards due to its toxic and flammable nature. When accumulated in enclosed spaces, methane can displace oxygen, leading to asphyxiation risks for individuals in the area. Moreover, sewer gas may contain harmful substances, including ammonia, hydrogen sulfide, and various organic compounds, which can pose serious health risks upon exposure. Long-term exposure to sewer gas can lead to respiratory problems, nausea, headaches, and other health complications.

While methane itself is not typically associated with water pollution directly, the other options, such as structural damage and increased utility costs, are not primarily linked to methane exposure, making health hazards the most relevant concern in this context. Understanding the impact of sewer gas on health is essential for ensuring safety and proper ventilation in plumbing systems.
