Safely Clear Blocked Sewers

Blocked sewers are often fixed within the walls of a building. However, there are times when work may be required beyond the outside walls.

It’s possible that natural gas lines could intersect with sewer lines outside your home or business. Unless the natural gas line is damaged, it does not pose an immediate safety risk. However, using motorized or water-jetting equipment to clear the sewer line could damage the natural gas line resulting in a serious safety issue.


Call Before You Clear

Call Ontario One Call at 1-800-400-2255 for a free Natural Gas Sewer Safety Inspection before trying to clear a blocked sewer line.

You don’t need to call if you or your plumber are:

  • Fixing the problem within the walls of the building.
  • Performing a conclusive video inspection to confirm there is no natural gas line in the sewer.
  • Attempting to clear a blockage with non-motorized equipment, such as plungers or push rods.

Damage to Natural Gas Lines

Signs that a natural gas line has been damaged during the clearing of a sewer service line could include:

  • bubbling water
  • a hissing sound
  • natural gas smell (rotten eggs)
  • blowing dirt

Damage to a natural gas line can result in a gas leak, fire or explosion.

If you smell gas or think you have a gas leak, leave the area and call us at 1-866-763-5427.
