Blocked Sewer Line

Blocked sewer? Make this your first call

If you have a blocked sewer, you want it fixed as quickly as possible. But that could be dangerous if you don't get a sewer safety inspection done first.

The natural gas line underground may intersect with the sewer pipe outside your home. This is known as a cross bore. It can often sit without incident unless the gas line is damaged by water jetting or motorized equipment used to clear the sewer line. You or your plumber must call Ontario One Call for a sewer safety inspection before working on a blocked sewer.
