ANSWER FIRST
What does sewer line leak detection involve?
Sewer leak detection starts with the symptoms and the plumbing layout, then narrows the problem to a likely section of pipe. A provider may review recurring backups, slow drains, unusual odors, wet areas, unexplained landscape changes, or other signs before deciding which inspection method makes sense.
Because sewer piping can run below yards, driveways, floors, or other structures, guessing at the location can lead to unnecessary digging. A camera inspection may show the inside of the line, while other diagnostic methods can help determine where a leak or break is located when the internal view is not enough by itself.
Warning: Repeated sewage backup, wastewater entering the home, or suspected contamination should be treated promptly. Avoid direct contact with sewage and keep people and pets away from affected areas.
