Your sewer line is one of the most important (and least visible) parts of your home’s plumbing system. When everything is working properly, you probably don’t think about it. But when a sewer line develops a problem, the symptoms can quickly become hard to ignore. A sewer scope inspection gives you a look inside the pipe without digging up your yard.
Slow drains, recurring backups, unpleasant odors, or wastewater coming back into the home can all point to an issue somewhere underground.
So how do you know what’s actually happening inside your sewer line?
Using a specialized camera, a plumber can inspect the inside of the sewer line and identify problems that may otherwise remain hidden until they cause a major backup or sewer repair.
For Chicago homeowners in particular, sewer scopes can be especially valuable. Much of the area’s older sewer infrastructure uses clay piping, and many of these systems have been in the ground for decades. Over time, pipes can deteriorate, shift, crack, or become obstructed.
Here are some of the most common problems a sewer scope can reveal.
Root Intrusions
One of the most common problems found during a sewer scope is tree root intrusion.
Tree and plant roots naturally seek out water. As sewer pipes age, small gaps or joints can develop between sections of pipe. Roots can find these openings and grow into the sewer line.
Once inside, roots can collect debris and restrict the flow of wastewater. What starts as a small intrusion can eventually become a significant blockage.
A sewer scope can show where roots have entered the pipe and how extensive the intrusion is. Depending on the condition of the sewer line, the appropriate solution may range from routine maintenance to more extensive repair.
Debris and Foreign Objects
Not everything that goes down a drain belongs in a sewer line.
A sewer scope can reveal debris and foreign objects that have become lodged inside the pipe, including items such as sanitary wipes and feminine hygiene products.
Despite being marketed as “flushable,” many wipes do not break down in the same way as toilet paper. They can accumulate in the sewer system and contribute to blockages. Feminine hygiene products should also never be flushed.
Other debris can enter a sewer line through deteriorating pipes, broken sections, or connections to the system.
A camera inspection can help identify what is causing a blockage and where it is located, allowing your plumber to recommend the appropriate method of clearing the line.
Breaks and Cracks in the Sewer Line
Over time, sewer pipes can deteriorate.
This is particularly important for homeowners in Chicago and other areas with older housing and infrastructure. Many older sewer lines were constructed using clay pipe, a material that can last for many decades but is not immune to deterioration.
Age, soil movement, tree roots, repeated stress, and other factors can eventually contribute to cracks or breaks in the pipe.
A sewer scope can reveal cracks, fractures, or sections of pipe that have deteriorated. Identifying these problems before a major failure occurs can give homeowners an opportunity to address the issue rather than waiting for wastewater to back up into the home.
Shifting or Misaligned Pipes
Sewer pipes are installed underground, where they are exposed to soil movement and changing conditions over many years.
A sewer scope may reveal that sections of the pipe have shifted or become misaligned. When pipe sections move out of position, the resulting gap or change in the pipe’s slope can interfere with proper drainage and create a place for debris to collect.
In some cases, shifting can be subtle. In others, the misalignment can be significant enough to restrict the flow of wastewater.
The camera allows a plumber to see these changes and determine whether monitoring, maintenance, or repair is appropriate.
Why Chicago’s Older Sewer Lines Deserve Attention
Chicago is home to many older houses, and with older homes often comes older plumbing infrastructure.
Clay sewer pipes can provide many years of service, but no underground plumbing system lasts forever. Over time, sewer lines can develop cracks, breaks, root intrusions, shifting, or other problems, especially when regular maintenance has been overlooked.
That doesn’t necessarily mean an older sewer line needs to be replaced.
In fact, one of the biggest benefits of a sewer scope is that it provides information. Instead of guessing about what’s happening underground, your plumber can see the actual condition of the pipe and help you determine the next step.
Regular sewer maintenance can also help identify and address problems before they become major emergencies.
Why Sewer Scopes Are Important When Buying a Home
A sewer scope isn’t only useful when you already have a plumbing problem.
If you’re buying an older home, a sewer scope can provide valuable information about one of the home’s most expensive and difficult-to-access plumbing components.
A traditional home inspection generally cannot tell you what the inside of the sewer line looks like. A sewer camera inspection can.
Before purchasing a home, knowing whether the sewer line is clear and in good condition—or whether it has roots, breaks, shifting, or other problems—can help you make a more informed decision.
A sewer scope can potentially identify an issue before you become responsible for an expensive repair.
How Does a Sewer Scope Work?
A sewer scope is a relatively straightforward process.
A plumber accesses the sewer line through an appropriate cleanout or access point and sends a specialized camera through the pipe. As the camera travels through the sewer line, the plumber can watch the video in real time and look for abnormalities.
Depending on the equipment and inspection, the camera can help identify:
- Root intrusions
- Blockages and accumulated debris
- Sanitary wipes and other foreign objects
- Cracks and breaks
- Shifting or separated pipe sections
- Deteriorated pipe
- Other conditions affecting the sewer line
The result is a much clearer picture of what’s happening underground.
Don’t Wait for a Sewer Backup to Find Out What’s Wrong
Your sewer line is easy to forget about because you can’t see it.
But underground doesn’t mean maintenance-free.
Whether you’re experiencing recurring drain problems, purchasing an older home, or simply want to understand the condition of your sewer line, a sewer scope can provide information that isn’t available from the surface.
At The Plumbing Department, we use sewer camera inspections to help Chicago homeowners understand what’s happening inside their sewer lines. Rather than guessing at the cause of a problem, we can use the camera to see what’s actually there and help determine the best course of action.
