BackFlow Prevention

BackFlow Prevention cover

There is mandatory under the City of Toronto’s Water Supply By-law for property owners of industrial, commercial, institutional and some of the residential properties (as defined by the Ontario Building Code) to install a backflow prevention device on the water supply line(s) to their facility. This is done to help protect the safety of the City’s drinking water and isolate buildings from the City’s water distribution system, helping to ensure contaminants do not enter drinking water.
