Most homeowners don’t think about your sewerage system until it doesn’t work correctly. An improperly functioning sewer system can lead to backups which causes costly and extensive damage to your home. At NGI Trenchless Pipe & Sewer Repair, we provide prompt and reliable sewer repair in Atlanta ,GA, to protect your home. Knowing what causes sewer backups can help you prevent them from happening. Here are some of the most common:

Tree Roots

Roots travel too far underground and destroy your drains. They infiltrate into the drains and start growing inside them in search of water and nutrients. Over time, the roots can grow large enough to block the flow of water in the pipe and cause cracks. Prompt hydro jetting and sewer line repair are necessary to avoid a sewer backup.

Heavy Rainfall

Rains also lead to sewer backup. Suppose your area experiences heavy rains regularly. It’s most likely that the municipal drainage system will reach its maximum capacity. Once the flooding occurs, the floodwaters may travel to the drain lines connected to your property, causing backups.


If you notice that your system takes longer to drain the wastes or hear gurgling sounds from your toilet, it’s a sign that the lines are beginning to form clogs. The obstruction will likely cause backups and impact plumbing throughout your home. Calling experts to remove the blockage would be best. They also inspect the system to check the cause of the clogs and determine if you need sewer pipe line repair due to damages caused by clogs.

Damaged Sewer Pipes

Your drainage system is prone to damage, especially if it’s old and lacking proper maintenance. Drainage backups are likely to occur as a result of damaged lines. If you have old and damaged pipes, we recommend replacing the sewer line to avoid backups and other issues.
