If your sewer line is clogged, roots are the likely cause. Unfortunately, once the roots block the line, you will need to have them cleared by a plumbing professional, or possibly replaced. The good thing is that modern methods for sewer line repair and replacement are of minimal intrusiveness to your home and property. High-tech methods of sewer replacement no longer require the digging of trenches on your property and with the use of polyethylene pipe (HDPE); you are guaranteed zero root intrusion, zero leaks, no corrosion, and no more worrying about a clogged sewer line in your future.
