The answer to 'why is my sewer line clogged' is that there are several common causes, including tree roots, debris buildup, and broken pipes. Sewer line clogs can cause slow draining, gurgling noises, and even sewage backups in your home.
Tree roots are a leading cause of sewer line clogs. As roots grow, they can infiltrate and crack the sewer pipe, allowing debris to accumulate and block the flow. Flushing non-biodegradable items like wipes, grease, or hair can also lead to clogs over time. Older sewer pipes made of materials like clay or cast iron are also more prone to cracks and breaks that can cause blockages.
