The Causes of Sewer Backup
A sewer backup is typically caused by a blockage within your drains, preventing the flow of sewage from your home to the public sewer lines. Therefore, dirty and contaminated water starts backing up into your home, leading to serious health problems and property damage. Several factors can lead to sewer backup issues. They include:
Tree Roots
Tree roots are attracted to your sewer lines because of the moisture. As they creep the system, they cause pipe breakages and cracks, presenting a significant sewer back up issue. With time, wastewater starts oozing from the ground into your yard. Not to mention the big budget involved in dealing with such an emergency.
Grease and Oils
Sewer lines and grease do not mix, and when they do, serious problems ensue. Many householders in Canada, particularly in Etobicoke, Ontario, do not know this. If you have the propensity of pouring grease into your drains, then you should expect sewer backup problems in the future. That’s because the grease solidifies within the pipes, blocking wastewater flow.
Sagging Pipes
A sag in the sewer pipes occurs when the soil surrounding a section of the pipe collapse or sinks. That causes the drains to bend downward, creating a belly effect. Wastewater builds up in the bellied portion and causes blockage with time.
Other factors that may lead to sewer backup include the following:

Other factors that may lead to sewer backup include the following:
- A corroded/ageing network
- Blockage within the city’s sanitary sewers
- Blockage within your home’s sewer connection
- Collapsed sewer lines
- Spontaneous influx of too much rainwater/snow into the sewersA cracked sewer lateral
