Ontario Plumbing Code Requirements & Water Service Sizing
Commercial plumbing in Ontario is strictly governed by the Ontario Plumbing Code (OPC) under the Building Code Act, ensuring public health and safety. Key considerations for property managers and business owners include accurate fixture unit calculations to properly size water service and drain stacks, ensuring adequate flow and capacity. Backflow prevention is critical, with requirements for devices like reduced pressure zone (RPZ) valves or double check valve assemblies (DCVA) determined by the assessed hazard level of the connected system. For establishments involved in food service, the Ontario Food Premises Regulation R.R.O. 1990, Reg. 562 mandates specific grease interceptor sizing to prevent sewer blockages. Furthermore, the OPC mandates hot water storage temperatures of 60°C to inhibit bacterial growth, while delivery temperatures must be regulated to a safe 49°C, often achieved through the use of thermostatic mixing valves (TMVs), especially in accessible washrooms to prevent scalding injuries.
