Sewage backups can cause extensive damage to your home, leading to costly repairs and health hazards. A professionally installed backwater valve is your first line of defense against such disasters.
What Is a Backwater Valve?
A backwater valve is a device installed on your home’s main sewer line. It allows wastewater to flow out but prevents it from coming back in during heavy rainfall or sewer system overloads.
According to the Ontario Building Code, backwater valves are required in certain situations, such as when fixtures are located below the level of the adjoining street or when the building drain may be subject to backflow.
