What are the common causes of a sewer line backup?

Common causes of a sewer line backup include tree‑root intrusion, grease and scale buildup, and structural problems such as cracks, offsets, bellies, or collapsed sections. Most backups start when roots enter a joint or when grease hardens inside the pipe, which then traps debris and slows flow to a stop. A video camera inspection quickly shows whether it’s a soft blockage that can be cleared (auger, hydro‑jet) or a damaged pipe that needs trenchless lining or pipe bursting. Our team handles these issues for homeowners throughout Provo and nearby Utah County. Members of our Plumbing Wellness Program receive an annual sewer camera inspection to catch problems early. If sewage is backing up or the main line won’t drain, stop water use and schedule a camera inspection promptly.
