A leaking sewer line pipe is the perfect life source for tree roots as they carry a lot of water which provides a bountiful water source as well as nutrients and oxygen from sewage, all of which tree roots require. Once a root finds a leak it will grow into the pipe and cause blockages which prevents the flow of waste and does significant damage to your pipes. This can cause backups into your home which is a health emergency and lead to very costly repairs. Tree root intrusion is one of the most common causes of sewer line damage.
To save yourself from these expensive repairs the best thing to do is to try to prevent this from happening; let’s go over how to prevent tree roots from invading your sewer line.
1. Determine Where Sewer Lines Are Located. The first step in preventing tree roots in your sewer line is knowing where your sewer line is located. This will help you to know where to create a barrier and where to plant trees in your yard. Call 811 before you dig in your yard for more information, so you don’t cause damage by digging and hitting any lines, pipes, or cables.
2. Create a Barrier. Sewer line barriers can help to prevent root growth into sewer lines. Copper sulfate and potassium hydroxide are slow-release chemicals that are often used near sewer lines to prevent root growth in that area. You can also bury wood and metal barriers vertically along the sewer lines to prevent the roots from intruding into the pipes. Just be sure to bury them 6 to 12 inches deeper than the pipe.
