The answer to 'why is my sewer line clogged' is that there are several common causes, including tree roots, debris buildup, and issues with the sewer line itself. Sewer line clogs can lead to slow draining sinks, gurgling toilets, and even sewage backups in your home.
Some of the most frequent causes of sewer line clogs include tree roots that have grown into the pipes, flushing non-biodegradable items down the toilet, and issues with the slope or age of the sewer line. In some cases, the clog may be located in the main sewer line outside your home, which requires professional equipment and expertise to clear.
