Do I need a drain permit for installing backwater valve in Toronto

Installation of a backwater valve in multi-unit and non-residential buildings necessitates a separate drain permit. Please consult the Plumbing and Drain Permit Stand-Alone Application guide for details on submission requirements.

Premises that may Need a Backflow Device

The backflow of water can be a serious problem for Toronto’s water supply. According to the Ontario Building Code, building owners and site managers “shall ensure that backwater valves are installed in every plumbing fixture or branch line connected with a municipal drinking-water main, where necessary.” This is also true for other types of premises:
