A Backwater Valve is installed on the main line that transports sewage away from your house. Once properly installed, the backwater valve will only allow flow one-way. This guarantees sewage can only flow out, but not back in. This is achieved by a flap that opens one way towards the city sewer, and closes if any water tries to flow back towards the home.
Backwater Valves have been gaining popularity over the years due to the increase in flash flooding. This extreme weather can overloading the old Toronto sewer system with water and cause it to travel backwards into the dwellings it serves. This back flow not only causes terrible damage to your investment but also can create dangerous health hazards.
