Tree roots clogged your sewer pipe? What do you do now? Have you ever had the plumber snake out your sewer line and pull up a big clump of tree roots? If the first snaking out solves the problem, you can take some preventative measures like having an annual pipe-snaking done or use root killer or rock salt to kill the roots. Eventually, you will need to replace the sewer pipe because it is broken, collapsed or cracked which has allowed tree roots to grow inside and will continue to be a problem. You might want find which tree or bush is causing the problem and get rid of them. Dead trees or bushes don’t grow roots anymore so they won’t be the culprit.
