What is sewer backup?
Sewer backup is what happens when the city or town drainage system overflows and sends water back through the pipes, and right into your home or business. Possible causes include heavy rainfall, or a defective sump pump. The water and sewage may come from a septic tank, sewer, or storm drain. Sewage backup can cause a lot of damage, like mold and bacteria problems, and requires an immediate clean-up by specialists in sewage backup cleaning in Mississauga and Toronto.
3 causes of a sewer backup
- Sewage backflow: water flowing the wrong way.
- Lateral drain and drain stack clogs: a clog in the pipe that runs across your property’s boundaries, often on a shared sewer.
- Main drain or sewer line clog: if the clog is in the main line, any water you run will cause issues.
