Why Is Water Backing Up in My Drains?

Water backing up through drains, toilets, or manholes is a sign of a serious blockage or failure in your drainage system. When wastewater can't flow away, it has nowhere to go but back up through the lowest access point. This is a health hazard that needs urgent attention.

What to Look For

  • Toilets overflowing or filling when other fixtures are used
  • Water rising in sinks when the washing machine runs
  • Sewage coming up through shower or bath drains
  • Manholes overflowing in the garden
  • Water backing up only during heavy rain
  • Multiple fixtures affected simultaneously

How We Diagnose the Problem
