Multiple Fixtures Backing Up at Once
When your toilet, sink, and shower all drain slowly at the same time, the problem is in the main line, not individual fixtures. This is the most reliable early signal of a main sewer issue.
Gurgling Sounds from Drains or Toilets
Gurgling after a flush or when water drains means air is trapped — usually because of a partial blockage or root intrusion in the main line. Ignore it long enough and a full backup follows.
Sewage Odors Inside or Outside
A persistent sewer smell inside the house or a foul odor near the yard above the sewer line can mean a break or crack in the pipe. This is worth diagnosing with a camera before it worsens.
Unusually Green or Lush Patches in the Yard
A section of lawn that is noticeably greener or lusher than the surrounding area can indicate a slow sewer leak below grade. Tree roots follow that moisture and cause further damage.
Foundation Cracks or Sinkholes Near the Main Line
Long-term sewer leaks can erode soil and affect the foundation. By the time this is visible, a camera inspection is overdue. Early diagnosis is far less expensive than foundation repair.
