Sewer Line Repair & Replacement in St. Francis Heights, Daly City, CA
Graded lots settle, and settlement is the leading cause of bellies in hillside laterals. A belly produces blockages in the same location every time, and no amount of clearing changes the fact that a section of pipe now holds water instead of draining it.
What causes a belly in a hillside sewer line?
Ground settlement on graded or filled lots. The pipe sags where the ground moved, water pools there, and solids collect. It is a structural repair, not a cleaning problem.
