The most common signs of a main sewer line problem are multiple drains backing up at once, gurgling sounds from toilets when other fixtures drain, sewer odors near floor drains, slow drainage throughout the house, sewage stains in the yard, and unusually green grass directly above the sewer line.
Symptoms to watch for
- Multiple slow drains or backups happening at the same time
- Toilets gurgle when the washer or shower drains
- Sewer odors near drains, basement, or in the yard
- Sewage backing up into the lowest drain in the house
- Patches of unusually green or soggy grass over the sewer line
These signs almost always point to a main-line issue rather than a single drain. Confirm the location and cause with a sewer camera inspection, then we’ll quote drain cleaning, hydro jetting, or sewer repair as needed.
