Common Locations of Drain Blockages
Understanding where a clog forms helps indicate which entry point and line-clearing tool may be required:
- Sink or Tub Traps: Curved U-shaped pipes under sinks or tubs that catch hair, soap residue, or small objects.
- Room Branch Pipes: Smaller individual pipes connecting single fixture drains to the property's main drain pipe.
- Main Sewer Lateral: The main underground pipe taking building wastewater out to the municipal sewer line under the street. Learn about main sewer-line cleaning options.
- Outdoor Cleanout Access: Ground-level caps giving direct opening into main underground sewer lines.
