If a blockage becomes severe enough, it can prevent wastewater from flowing properly and cause it to back up into your house. - **Tree roots:** Tree roots can grow into your sewer lines and cause blockages. This is a common problem in older homes, as the sewer lines are often made of clay or cast iron, which are more susceptible to root damage. - **Damaged sewer lines:** Sewer lines can be damaged by a number of things, including earthquakes, excavation, and construction. If a sewer line is damaged, it can allow wastewater to leak out and cause a backup. **Effects of Sewage Backups** Sewage backups can have a number of negative effects on your property and your health.
