How can I prevent the invasion of roots in the main sewer line?
The best long term solution to root problems is to replace the pipe. Because this is a very expensive prospect, Vertex Mechanical offers these alternatives to replacement. Vertex has equipment to remove roots from the sewer system. And preventing the return of roots can be done with a two or three part maintenance program. First the pipe will probably need to be cleaned on a yearly basis. Second a chemical root destroyer can be added on a monthly or more often basis. Thirdly if the roots are at a known spot in the pipe, a root destroyer can be added outside the pipe to kill the roots (but not the tree) in the area of the pipe.
