If you hear a gurgling noise when you flush, it often means air is trapped in the line due to a blockage. This is a clear sign that the problem is in the main sewer line, not just one fixture.

Another red flag is if sewage backs up into lower drains, such as a basement floor drain or a first-floor shower, when you flush upstairs. This indicates the blockage is preventing proper drainage throughout the system.

What to do if you suspect a main line blockage
