Signs Your Sewer Line May Be Collapsed or Bellied

A collapsed or “bellied” sewer line (a section that has sagged and can hold wastewater) can cause persistent blockages, backups, and unpleasant odors. Because the damage can worsen over time, recognizing the early warning signs is key to protecting your home and avoiding expensive repairs.

Common signs of a collapsed sewer line and a bellied line often overlap, but some symptoms are especially suggestive.
