A sewage backup is a serious problem that can cause significant damage to your home and health. It’s important to understand the causes and effects of sewage backups to prevent them from happening or to mitigate their impact if they do occur.
### Causes of Sewage Backups
There are several common causes of sewage backups, including:
**Tree roots:** Tree roots can grow into sewer lines and block them, causing sewage to back up into your home.
**Grease accumulation:** Grease can build up in sewer lines and harden, forming a blockage that prevents sewage from flowing properly.
**Foreign objects:** Flushing foreign objects, such as diapers, wipes, or feminine hygiene products, can also block sewer lines.
**Damaged sewer lines:** Sewer lines can be damaged by earthquakes, heavy rains, or other events, which can cause them to leak or collapse.
### Effects of Sewage Backups
Sewage backups can have a number of negative consequences, including:
**Health hazards:** Sewage contains harmful bacteria and viruses that can cause illness if they come into contact with humans.
**Property damage:** Sewage backups can damage floors, walls, and other surfaces in your home, leading to costly repairs.
**Insurance claims:** Sewage backups can be covered by homeowners insurance, but filing a claim can increase your premiums.
### Why Is Sewer Backing Up in House?
There are several reasons why sewer lines can back up into houses, including:
**Clogged sewer main:** The main sewer line that runs under your street can become clogged, causing sewage to back up into your home.
**Damaged sewer lateral:** The sewer lateral is the pipe that connects your home to the main sewer line. If this pipe is damaged, sewage can back up into your home.
**Low water levels in the sewer line:** If the water level in the sewer line is too low, it can cause sewage to flow back into your home.
