Call 811 before inspecting or clearing sewer lines

If you encounter a blockage in a sewer lateral, it could be caused by a natural gas line that was inadvertently drilled or bored through the sewer line in what is known as a “cross bore.” Cutting into a cross-bored natural gas line can result in a fire or explosion. Before clearing any blocked sewer lateral, take precautions to determine whether a cross bore exists and use the least invasive equipment possible.

All gas piping downstream of the gas meter to gas-fired appliances or other structures on the property is the responsibility of the home/property owner or current occupant.

NorthWestern Energy is required to inform customers with privately owned natural gas or propane service lines of their responsibility to inspect and maintain their piping (Code of Federal Regulations 49 CFR 192.16). Customers should have the pipes periodically inspected for leaks, and metallic pipes should also be inspected for corrosion by qualified professionals, such as your local plumber.

Any unsafe conditions should be repaired immediately, or the flow of gas should be shut off.

Carbon monoxide safety tip:

Make sure you have a working carbon monoxide alarm installed on every level of your home, especially around sleeping areas, and test your alarms every month.
