Common Water Issue in BC
Gurgling Drains — Vent or Sewer Line Issue
Drains that gurgle, bubble, or drain slowly may indicate a venting problem, partial sewer line blockage, or in some cases, a leak in the drain system allowing air infiltration.
Possible Causes
- •Blocked or partially collapsed vent pipe on roof
- •Partial sewer or drain line blockage creating air pressure changes
- •Drain pipe leak allowing air to be drawn into the system
- •Clogged main stack or building drain
- •Frozen vent pipe in winter months
Recommended Steps
- 1Check if gurgling occurs in multiple fixtures — indicates main issue vs. single fixture
- 2Listen for gurgling when running water from upper floors — checks vent function
- 3Check roof vent pipes for blockages from leaves, debris, or animal nests
- 4Monitor for slow drainage or backups accompanying gurgling sounds
- 5Call professional drain inspection with CCTV for sewer line assessment
