How to Clear Sewer Lines of Roots
Tree roots that are growing around a sewer line have a way of finding the smallest of cracks that they can penetrate. At first, the root is small, but as it soaks up water, they grow. In time, they can become as big as the sewer line itself. You may notice your drains gurgling more than normal. Water drains out of the basin slowly and your toilet may need more plunging to keep it from overflowing. This is an indication that tree roots are plugging your sewer line. Does this Spark an idea?

Hire someone to come in and snake the line out for you with a powered sewer auger. You can also rent a power auger and do the job yourself. The rotating head cuts away the roots like a reciprocating saw blade. This will only remove 50 to 60 percent of the roots. The other 40 to 50 percent will remain alive and continue to grow.

Let the last 1/2 cup of copper sulfate remain in the toilet bowl overnight. Do not use the toilet during this time. The next morning, flush the toilet.

Apply copper sulfate in this manner twice a year. Do this once in the spring when the trees are coming out of dormancy and starting to grow. Do it again in the fall when the trees are dropping their leaves.
