Multiple Drains Backing Up in Stevens Point, WI

Understand the symptom

What can multiple drains backing up mean?

One backed-up sink or tub can be caused by a clog in that fixture's branch drain. When toilets, showers, sinks, or floor drains react together, the problem is more likely to be downstream where those drain lines join the home's main sewer lateral.

Backups may begin intermittently and become more frequent as a restriction worsens. Running a washing machine, draining a bathtub, or flushing an upstairs toilet can force wastewater out through a lower shower or basement floor drain because the flow has nowhere else to go.

Possible sources

Common causes to consider

Protect the property

What should you do now?

• Stop flushing toilets and pause showers, laundry, dishwashing, and other water use.
• Keep children and pets away from any wastewater and avoid contact with contaminated surfaces.
• Do not add chemical drain cleaner; it may not reach a main-line obstruction and can create another hazard.
• Request main sewer line clearing and an inspection if the backup is severe, recurring, or affects several fixtures.

Find the cause

How the problem is typically diagnosed

1. 1

   Compare affected fixtures

   The location and order of backups help distinguish a branch-drain clog from a main-line problem.

2. 2

   Check the cleanout

   A suitable cleanout may provide evidence of a full line and a safer access point for clearing equipment.

3. 3

   Restore flow

   Mechanical clearing or hydro jetting may be used when appropriate to open the line.

4. 4

   Inspect the pipe

   A camera can look for roots, offsets, buildup, bellies, or structural damage after the line can be viewed.
