Absolutely, tree roots in your yard can cause sewer backup. While trees may look beautiful and add shade to your yard and home, their extensive root systems can wreak havoc on underground pipes. This occurs because tree roots are naturally drawn to water and nutrient sources. When tree roots find their way into these pipes, sewer blockages, backups, and huge repair bills can result. If you’re facing a large bill, be sure to get a 2nd opinion on price using the trenchless sewer repair method.
As a homeowner, you are responsible for the pipes that lead from your home to the city sewage system (called lateral pipes). This means you are liable for any damages and/or expenses incurred by invading tree roots. (Exact rules will vary per city, and some Texas cities such as Irving may provide funds for certain drain cleaning procedures.)
How Roots Get Into Sewer Lines & Drains
While roots may seem fragile, they are actually incredibly strong, resilient, and determined. They act as a lifeline for the tree, sending out small feeder roots that seek valuable water and nutrients. These roots are drawn to the warm water inside main sewer pipes that release vapor into the soil. This vapor typically escapes through a small crack in PVC piping, or through a loose joint in older pipelines made of clay, concrete, iron, Orangeburg, or other less resilient materials. These types of soils are present across DFW, and prominent cities like Plano and Richardson.
When the roots detect this warmth and moisture they begin growing towards it. When a weak spot in the pipe is discovered, the roots invade and grow inside of it. Once inside, they will continue to expand, which in turn causes the opening in the pipe to grow larger and allow for more vapor and moisture to be released. Hair-like root systems then continuously grow within the pipe, completely filling it and blocking the flow.
These systems will stop anything trying to make its way through the pipe, including tissue paper and other debris. This essentially acts as a fertilizer, turning the pipe into a literal food pipeline for the tree. As a result, the roots grow larger to deliver more and more nutrients to the healthy, growing tree.
As roots increase in diameter, they put a strain on the pipe joints and gradually break the clay, concrete or other materials, leading to a total collapse of the pipe. (Note: this article is about sewer lines which concern the drainage of water away from your home. Water lines bring water into your residence, and can experience similar problems as galvanized pipes break down. This is why the City of Arlington recommends having old water lines replaced.)
Common Indicators of Root Problems
A slowly draining system signaling time for cleaning is a common indicator of root problems. If gurgling sounds are coming from your toilet bowl, it may be a sign that there is root blockage in your drain pipes. We use a special hydro jetting service to clear these types of blockages.
If the shower or sink drains slowly, even after they have been cleaned out, it is a possible sign of root blockage. Not every issue means there are tree root problems, and many clogs can be resolved by using a plumber’s snake. If this problem goes unattended, it may lead to water backing up into your home, which can cause costly water damage or burst pipes. Conversely, if you notice drainage issues suddenly disappearing, a thorough yard inspection may reveal wet areas around sewer laterals that are the result of collapsed pipes.
