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. Proper sizing of water services and drain stacks relies heavily on fixture unit calculations, which determine the potential demand on the system. Backflow prevention is a critical component, with requirements for devices like Double Check Valve Assemblies (DCVA) or Reduced Pressure Zone (RPZ) assemblies dictated by the assessed hazard level of the water supply connection. For food service establishments, the Ontario Food Premises Regulation R.R.O. 1990, Reg. 562 mandates the proper sizing and installation of grease interceptors to manage wastewater effectively. Furthermore, the code specifies hot water requirements, typically involving 60°C storage temperatures to prevent bacterial growth and 49°C delivery temperatures at fixtures. Thermostatic Mixing Valves (TMVs) are also required for accessible washrooms to ensure water is delivered at a safe temperature, preventing scalding injuries.
