Sewage Backing Up Into Toilets or Showers
Wastewater returning through a toilet, shower, or bathtub can indicate a restriction in a shared building drain or sewer lateral.
The situation may become more serious when someone uses another fixture, such as a washing machine, and additional wastewater enters the blocked system.
Avoid repeatedly flushing toilets or running water in an attempt to push the blockage through.
If you want to understand how different blockages cause wastewater to return through fixtures, read our guide to sewer backup problems.
