ROOTS.....uggghhhh!!!! Root intrusion into sewer lines is an amazingly common problem. Trees, bushes, shrubs and various other plants have roots that naturally seek out the best source of moisture and are attracted to the limitless supply of wastewater found in sewer lines.
Roots can enter through any joint or gap in the pipes. As they draw moisture from the sewer line, these roots not only multiply, but expand - which over time leads to structural decay of the pipe and eventual collapse. Contrary to popular belief, however, it is possible to address the problem effectively without cutting down the tree or removing the plants.
