Quick Answer
How do you find a sewer line leak or problem?
A small waterproof camera is fed through a cleanout into the sewer line, showing cracks, offset joints, roots, sagging sections and blockages on a monitor. A locator on the surface marks where problems are so repairs can be planned precisely.
What Sewer and Drain Leak Detection Includes
A camera inspection records what is actually happening in the line.
Location marking
A surface locator marks the depth and position of problem areas.
Drain testing
Fixtures and floor drains are checked for slow drainage and odors.
Report
You receive a description and, where possible, video of the findings.
House Sewers and Drains in Oak Park
The Village of Oak Park explains that nearly all homes use gravity sewer systems with house sewer lines about 4 to 6 inches in diameter, and that many homes route toilets, sinks and downspouts into the same house sewer. In many older parts of the village the underlying lines are clay tile or cast iron, both of which crack and shift with age and tree roots.
Responsibility generally divides at the street. The Village maintains public sanitary and storm sewers, which connect to Metropolitan Water Reclamation District interceptors. Private house sewers, from the building out to the public main, are usually the property owner's responsibility. Ask the Village if you are unsure where yours ends.
Signs of trouble include gurgling drains, slow drainage in multiple fixtures, sewage odors, wet spots over the line and repeated clogs. For backups tied to storms, read flood detection and prevention and our article understanding the signs of sewer line leaks in Oak Park.

Frequently Asked Questions
Straight answers about sewer & drain leak detection in Oak Park.
Who is responsible for the sewer line in Oak Park?
The Village maintains public sewers; the house sewer from the building to the public main is typically the owner's responsibility. Check with Public Works at 708.358.5700.
What are signs of a sewer line leak?
Slow drains, gurgling, sewage odors, wet or sunken spots in the yard and repeated clogs.
Can a camera inspection find roots?
Yes. Roots are visible entering joints or cracks.
Does a sewer repair need a permit?
Usually yes. Ask the Village Permits Processing Division at 708.358.5430.
Is a sewer backup the same as a leak?
Not exactly; a backup is flow reversing, often during storms, while a leak is escape from the pipe. Both can be investigated with camera work. See basement and foundation leak detection.
How can I reduce backup risk?
Disconnect downspouts, avoid washing machines and dishwashers during heavy rain, and consider overhead sewers or backflow prevention.
