**Maintaining and Repairing Sewer Lines**
Proper maintenance of sewer lines is crucial to prevent sewage backups and costly repairs. Inspection of sewer lines can be conducted using advanced video technology to identify potential issues before they cause significant problems. Routine cleaning of sewer lines can be scheduled to remove buildup and prevent blockages.
**How to Clean a Clogged Main Sewer Line**
1. **Locate the cleanout access point:** Usually located in the basement or near the foundation of the house.
2. **Insert a drain snake:** Feed the snake into the cleanout and turn the crank to clear the blockage.
3. **Use a chemical drain cleaner:** Pour the cleaner into the cleanout and follow the instructions on the label.
4. **Contact a professional plumber:** If the above methods fail, call a qualified plumber to address the issue.
