5 Warning Signs Your Sewer Line is About to Fail

Sewer line failures rarely happen without warning. Here are the five signs we see most often on Davenport service calls.

1. Multiple slow drains at once

If your kitchen, bath, and basement floor drain are all slow simultaneously, the issue isn't any one branch — it's the main line.

2. Gurgling toilets

A toilet that gurgles when the washing machine drains is venting through the wrong path because the main is partially blocked.

3. Sewer smell in the basement

A dry trap is the easy answer. If the trap has water and the smell persists, the line has a crack or break.

4. Soggy or unusually green lawn patches

Especially over the path from the house to the street. Sewage is fertilizer — the grass tells on the leak.

5. Recurring backups

If you've snaked the main twice in a year, the clog isn't the problem — the pipe is. Time for a camera inspection.
