Sewer Line Problems: Warning Signs and Fixes

Signs Your Sewer Line Has a Problem

One slow drain can be local. Several at once points to the main line.

• Multiple drains slow or backing up together.
• Gurgling toilets or drains after flushing.
• Sewage odors indoors or in the yard.
• Wet or unusually green patches over the sewer path.
• Water backing up in a basement floor drain.

What Damages Sewer Lines

Common causes include:

• Tree and shrub roots entering joints.
• Older clay, cast iron or Orangeburg pipe that cracks or collapses.
• Grease and wipes building up into blockages.
• Shifting soil that separates or bellies a pipe.

Camera Inspection and Repair Options

A sewer camera shows the pipe condition, the blockage and its location. From there the options typically include:

• Hydro jetting or cleaning to clear buildup and roots.
• Spot repair for a localized break.
• Trenchless lining or pipe bursting in some cases.
• Full replacement when the pipe has failed along its length.

Frequently Asked Questions

How do I know it is the sewer line and not one drain?

If several fixtures back up together or a basement drain overflows, the main line is the likely cause.

Can tree roots really get into a sewer pipe?

Yes. Roots find small joint gaps and grow inside the pipe.

What does a sewer camera inspection show?

The pipe condition, any breaks or roots and the exact location of problems.

Should I keep using water during a backup?

Limit water use until the line is cleared to avoid more overflow.
