Sewage backups are a homeowner's worst nightmare. They can be unsanitary, embarrassing, and expensive to clean up. There are numerous causes of sewage backups, but the most common include: - **Tree roots:** Tree roots can grow into and clog sewer lines, causing sewage to back up into your home. - **Grease:** Grease can build up in sewer lines and cause clogs. Pouring grease down the drain should be avoided. - **Foreign objects:** Flushing foreign objects down the toilet can clog sewer lines. - **Damaged sewer lines:** Sewer lines can be damaged by construction, earthquakes, or other events. - **Improperly installed plumbing:** Improperly installed plumbing can cause sewage to leak into your home. The effects of a sewage backup can be devastating. Sewage can contaminate your home's water supply, making it unsafe to drink or bathe in. It can also damage your home's structure and furnishings. If you experience a sewage backup, it is important to contact a professional Sewage Cleanup Service immediately. They will be able to clean up the mess and prevent further damage to your home.
