  • 3 Methods in Eradicating a Tree Root Sewer Pipe Infestation


    A tree root sewer infestation is pretty common in households that have large trees or shrubs near the premises of their house. It’s not just the size of the tree that determines if the roots can be invasive and large, there are also other types of medium sized plants that have roots that deep underground and are very invasive when looking for rich soil and water. Below, you will find some different methods in eradicating or lowering the amount of tree roots that have infested your sewer line. Take note that each of method will vary on effectiveness, duration, work & time required, and of course, equipment and supplies.

    1. Root out the tree that’s causing the root attack

    If you want to get rid of the roots’ source and don’t want to be bothered by the current root attack again, then the best solution for you is to take out the tree that’s the source of the roots. It’s most likely that tree or shrub species has extremely aggressive roots so you may have no other option than to uproot the tree. This is also a viable method if the pipes are already too damaged from the roots. Of course, preventing the root attack from getting worse will prevent you from spending a ridiculous amount of money for a major pipe repair. In the future or if you want to put another plant near your home, be sure that the tree species are “sewer-safe”(meaning the roots are not disruptive and can only dig on shallow soil).

    2. Trimming the roots

    A mechanical auger can be rented and used for slicing down some small roots that have invaded your pipes ―— but if you want to have a more professional cleaning then you need to hire a plumber or sewer engineer. This method isn’t really the most effective since there are roots that can’t be cut down by the mechanical auger, especially medium to large sized roots. Even if you have already successfully cut the roots, it will still remain in the sewer pipe and must be extracted manually or it will just become a cause of clog. Of course, if you let a professional do it, the task will be non-existent and it will be safe to know that the cleaning is done expertly and without any major flaws. There are still homeowners who prefer this sewer pipe maintenance more since they often don’t want to go through the hassle of extracting the tree of the roots or they just grew fond of the plants in their vicinity.

    3. Root killer herbicides

    There are herbicides that are very effective in killing roots in the sewer pipe and even repress other invading roots near the sewer line. Most of these herbicides contain copper sulphate; a well-known compound that is basically poisonous to trees and other plant life. A common way of killing the roots with the use of these herbicides is by flushing down the chemicals into the toilet bowl. The toilet pipe connection goes directly to the main sewer pipeline which is why this is where the herbicide must be poured. Just like the mechanical auger solution, the roots will still remain in the pipeline and must be taken out manually or by flushing down the pipeline with a hydro jet.
