Ontario Plumbing Code Requirements & Water Service Sizing
Commercial plumbing in Ontario is strictly governed by the Ontario Plumbing Code (OPC), which falls under the Building Code Act, ensuring public health and safety. Key aspects include accurate fixture unit calculations to properly size water service lines and drain stacks, preventing issues like low water pressure or back-ups. Backflow prevention devices, such as Reduced Pressure Zone (RPZ) or Double Check Valve Assemblies (DCVA), are mandatory and selected based on the potential hazard level to the potable water supply. For establishments involved in food service, grease interceptor sizing must comply with the Ontario Food Premises Regulation R.R.O. 1990, Reg. 562, to prevent sanitary sewer blockages. Furthermore, hot water systems require specific temperature controls, with recommendations for 60°C storage to prevent bacterial growth and 49°C delivery to prevent scalding, often necessitating Thermostatic Mixing Valves (TMVs) in accessible washrooms to meet safety standards.
