Do you have a tree in your yard? If so, then it’s most likely that its roots are slowing invading your sewer line. Sewer pipes are a favourite spot of roots since it contains a lot water and soil. These are what trees need for nourishment. Trees aren’t the only culprit of a root invasion. Some medium-sized bushes can actually enter a sewer line and take it over. Roots shouldn’t stay in the sewer pipes for a long time. It will continue to grow and even destroy the pipes. Some collapsed pipelines can still be repaired while others need to be replaced no matter what. Follow the tips below and learn how to kill the roots that are tangling in your sewer line.

Removing the roots and its source

The best and permanent way to kill the roots is to eliminate the source — the tree. If you have no trouble uprooting the tree then this should be one of your primary options. Some tree species don’t have any business being planted in a household yard in the first place. For example: willow trees are notoriously known for its invasive and massive roots. You should avoid planting these types of trees since it will definitely try to take over your sewer line. Don’t forget to have the stump removed and the other prevalent roots. Tree-cutting professionals should already know this but just remind them just in case. To those who want to plant a different type of tree; make sure it’s not aggressive and have big roots.

Using herbicides

There are different types of herbicides so be sure to pick one that’s specifically made to kill roots. Copper sulphate crystals are widely used in killing roots that are already in the sewer line. All you have to do is flush the chemicals into your toilet. Avoid putting the chemicals in sink drains or bathroom floor drains. This will cause the copper sulphate to take a long time to take effect.

Flushing the chemicals in the toilet is the best option since it will go directly into the sewer line. Another alternative is by spreading the copper sulphate all over the soil near the sewer line. This will stop the roots from going to that soil due to the chemicals’ poisonous effects. Using herbicides can definitely kill the roots but it won’t stop the source. The roots will continue to grow and you must apply chemicals periodically. This will help stop them from invading your sewer line.

Using mechanical cutters

The mechanical cutter used is more of an auger tool type. The sewer auger has rotating cutting blades that enable it to slice down growing roots. This method is best used for maintenance and not for a permanent solution. Sometimes the cutters aren’t able to cut down all of the roots in the sewer line. The roots tendrils even grow back. The sewer auger method is suitable for those who don’t want to cut down the tree source and prefer maintaining the sewer line.
