How a Sewer Camera Inspection Reveals Hidden Drain Problems

A sewer camera inspection is one of the most accurate ways to diagnose a drain problem before deciding how to fix it.

Without a camera, a drain problem is largely invisible. A technician can clear a blockage and restore flow, but if the underlying cause is not identified, the problem is likely to return. A sewer camera inspection removes the guesswork by showing exactly what is happening inside the pipe.

Homes throughout Plymouth, Rogers, and the surrounding North Metro often have underground sewer systems that have never been inspected. Problems can develop slowly over years before any symptoms appear at the surface.

What a Sewer Camera Inspection Is

A sewer camera inspection uses a flexible cable with a small waterproof camera attached to the end. The camera is fed into the drain line through a cleanout access point or drain opening.

As the camera moves through the pipe, it transmits live video to a monitor. The technician can see the interior of the pipe in real time and identify any issues present inside the line.

The inspection is non-invasive. It does not require digging or disrupting the yard or foundation.

What a Sewer Camera Inspection Can Find

A camera inspection can identify a range of problems that would not be visible from the surface.

Common findings include:

• Tree root intrusion — roots entering the pipe through cracks or joints and collecting debris over time. This is one of the most common findings in North Metro communities with mature tree canopies. You can learn more about how tree roots in sewer lines develop here.
• Grease and debris buildup — accumulated material narrowing the pipe and restricting water flow
• Pipe cracks or fractures — damage to the pipe wall that may allow groundwater intrusion or root entry
• Offset or separated joints — sections of pipe that have shifted out of alignment over time
• Bellied pipe — a sag in the line where waste collects instead of flowing freely
• Blockages — objects or buildup causing a partial or complete obstruction

Each of these issues requires a different approach to resolve. Identifying the exact cause before beginning work helps ensure the right solution is used the first time.

When a Sewer Camera Inspection May Be Recommended

A camera inspection is not always necessary for every drain problem. For straightforward clogs, professional drain cleaning is often the first step.

However, a camera inspection is typically recommended when:

• Drain problems keep returning after being cleared
• Multiple drains are backing up throughout the home
• A home is being purchased or sold and the sewer system has not been recently inspected
• The home is older and the sewer system has never been evaluated
• There is concern about root intrusion based on tree location and pipe age
• A previous cleaning identified heavy buildup or unusual resistance in the line

In many cases, a camera inspection is performed after a professional drain cleaning service to confirm the line is fully clear and assess the overall condition of the pipe.

What Happens After a Sewer Camera Inspection

After the inspection, the technician can explain exactly what was found and what options are available.

If the pipe is in good condition and the issue was buildup or a simple blockage, routine drain cleaning may be all that is needed.

If root intrusion is present, hydro jet drain cleaning may be recommended to remove the roots and flush debris from the line. You can learn more about how hydro jet drain cleaning works here.

If the pipe shows signs of damage, cracking, or significant deterioration, additional evaluation may be recommended before deciding on next steps.
