Cross Bore Information
If You Have a Sewer Line Clog, Check for a Cross Bore Before You Try to Clear It!
What is a Cross Bore?
A cross bore occurs when a utility line is drilled, or bored, into or through another utility’s line (see image below).
Construction crews sometimes perform pipeline installation using trenchless technologies, or boring, in addition to other construction methods.Be Aware of Sewer Backups & Repairs
In the event that a gas line was accidentally installed through a sewer line, the cross bore can create a sewer backup in the home. You do not have to be a natural gas customer to experience a sewer issue due to a cross bore, and not all sewer issues are caused by a cross bore.
If there is a sewer line backup, check for a cross bore before trying to clear it! Before anyone uses a tool to clear the clogged sewer line, we suggest using a camera to check for a cross bore.
Using any type of line clearing tools could damage the gas line, allowing gas to escape. Gas that escapes can migrate, or travel, and enter buildings and homes. If under the right circumstances the gas is ignited, it could cause severe injury or death.
If you smell gas or have any gas emergency, leave the area immediately, then call 911 and us at 888-482-4950. Do not operate any electrical equipment including phones, light switches, garage doors or vehicles until a safe distance away.
