Blocked sewer line? It could be a cross bore
If your sewer line is backed up, clearing it without checking for underground utilities can be dangerous. Learn how to identify risks and take the right safety steps before you begin.
A hidden hazard
A cross bore happens when one underground utility line accidentally goes through another — often when new lines are installed without digging a trench. In rare cases, a natural gas line may be drilled through a sewer pipe. A common warning sign of this problem is a sewer blockage that causes wastewater to back up into your home or yard.
If your sewer backs up, you or a plumber may try to clear the line using mechanical tools. But this can be dangerous if a gas line or other utility is accidentally struck. That’s why LG&E strongly recommends having the sewer line inspected with a camera before using any equipment that cuts or drills.
