Greenwich's sewer system includes clay and cast iron laterals installed decades ago, especially in neighborhoods like Belle Haven, Byram, and Glenville. These materials degrade over time, developing cracks and joint separations that allow tree roots to enter. When roots infiltrate your lateral, they create partial blockages that trap air and cause toilet bubbling. Combined sewer systems in older parts of town also experience backflow pressure during heavy rain, pushing air back through your drain system. If your home was built before 1970, your sewer lateral likely needs inspection.
