Main line clogs can be frustrating because they often affect more than one drain at a time. In this Coeur d’Alene job, the blockage was caused by a large amount of roots growing into the sewer line.
Root intrusion is one of the more common causes of recurring sewer problems, especially in older lines or areas with mature trees. For homeowners needing service in the area, Scott’s Plumbing provides plumbing and drain work throughout Coeur d’Alene and nearby communities.
Clearing the main line first
The first step was to cable the main line and remove the roots that were blocking the pipe. The photo shows the cable machine pulling a heavy root mass from the cleanout, which explains why the drain was not flowing properly.
When roots enter a sewer line, they can catch debris, slow the flow, and eventually create a full blockage. Simply getting the water moving again is not enough if the roots are still present inside the pipe.


Camera inspection after cabling
After the line was unclogged, a sewer camera was used to inspect the inside of the pipe. This step helps confirm that the blockage was cleared and gives a better look at the condition of the line after the roots were removed.
Camera inspection is especially useful with root problems because it can show whether the line is clear, if more work is needed, or if there are areas of concern such as cracks, separations, or heavy intrusion points.
Treating the line with RootX
Once the drain was flowing and the line had been checked, RootX foaming root killer was applied to help slow future root intrusion. The foam is designed to contact the inside of the pipe and treat root growth along the pipe walls.
This type of follow-up treatment can help extend the results of the cleaning and reduce the chance of roots quickly returning. It is often used as part of a longer term approach to drain cleaning and main line maintenance.
Why roots come back
Roots are naturally drawn to moisture, and even a small opening in a sewer line can attract growth. Once roots find their way in, they tend to return unless the pipe is repaired, replaced, or maintained with regular cleaning and treatment.
- The main line was cabled to remove the blockage.
- A large amount of roots was pulled from the sewer line.
- The line was inspected with a camera after clearing.
- RootX foaming root killer was applied to help slow root regrowth.
When sewer line repair may be needed
If root intrusion continues to return, there may be damage in the sewer line that needs a more permanent repair. Cracked pipe, separated joints, or old clay sewer lines can give roots an easy path back into the system.
For repeated backups or heavy root intrusion, a closer look at the pipe may help determine whether ongoing maintenance or sewer line repair is the better long term option.
