How to tell if roots in sewer line?

You could attempt to cable the sewer line to see if any roots actually get caught on the cable when it gets pulled out of the pipe. This is the less expensive way, but isn't as accurate, as sometimes the roots fall off the cable upon pulling it out of the pipe. Also, this will not tell you the extent or location of the root infiltration(s).


The most prudent thing to do is have someone perform a Video Inspection of the sewer line. In this way, you not only see if there are roots growing into the line, but more importantly exactly where they are. A large portion of the companies offering video inspection services have the ability to electronically locate the head of the camera, pinpointing exactly which areas are impacted by the roots, among any other issues, while your looking at them.

With this information, you will know exactly what, where, and how deep the problems are with the sewer line. This comprehensive view of the overall health of the system will allow you to make an intelligent decision to either repair it or simply maintain it.
