Bathroom warning signs of a sewer line issue include slow-draining tub or shower, gurgling toilet when the sink or washer drains, sewer odor near floor drains, water backing up into the tub when the toilet flushes, and dampness or mold appearing on bathroom walls without obvious cause.

Bathroom red flags

  • Slow tub or shower drain
  • Toilet gurgles when other fixtures drain
  • Sewer odor near the floor drain
  • Water in the tub when toilet flushes
  • Multiple drains slow at the same time
  • Damp or moldy bathroom walls

Confirm with a sewer camera inspection, then quote drain cleaning, hydro jetting, or trenchless repair.
