When sewer bubbles appear, they typically indicate a sewer line issue such as a blockage or leak. Immediate steps include checking for visible signs like soggy ground, foul odors, or water backups. Avoid using harsh chemicals, as they may worsen the problem. Contact a licensed plumber or sewer inspection company to diagnose the issue. If the problem persists, consider scheduling a video pipe inspection to identify hidden cracks, roots, or debris.

Sewer bubbles often result from root intrusion, grease buildup, or pipe corrosion. Tree roots, particularly from oak or maple species, account for 30% of sewer blockages in the U.S., according to the Environmental Protection Agency (EPA). Grease from food waste forms a sticky coating that traps debris, contributing to 25% of household sewer backups, as reported by the American Water Works Association. Corroded pipes, common in older infrastructure, can develop leaks, with 15% of U.S. water utilities citing aging pipes as a primary cause of sewer issues. The CDC notes that sewage leaks can contaminate groundwater, increasing risks of waterborne diseases by 20% in affected areas. Proactive measures, such as using enzyme-based cleaners and avoiding excessive tree growth near sewer lines, can reduce recurrence. A professional inspection using high-tech cameras and hydro jetting ensures thorough diagnosis and repair, preventing costly property damage. Data from the National Association of Home Inspectors shows that timely sewer line maintenance can save homeowners up to $4,000 in emergency repairs.
