Commercial, Institutional and Medical Gas Systems
Plumbing for large commercial and institutional buildings under the Ontario Building Code, the CSA B481 series and CSA Z7396.1, followed through an apprentice finishing a Hamilton mixed-use tower and building a hospital wing: what changes in big buildings; storm drainage by the rational method; controlled-flow and siphonic roof drainage; grease interceptors and FOG programs; oil, sand, solids and amalgam separators; booster pumps and pressure zones; tall drainage stacks; laboratory, acid and hospital waste; medical gas sources, pipelines, brazing, testing, verification and installer certification; fire service backflow protection; and commercial fixtures, water conservation, coordination and commissioning.

What you'll learn
- Describe how plumbing systems, roles and approvals change in large commercial and institutional buildings, and estimate peak demand for added tenant spaces.
- Calculate storm drainage flows with the rational method from roof area, wall area and design rainfall, and explain secondary drainage and on-site storage.
- Explain how controlled-flow and siphonic roof drainage work, calculate roof storage and loads, and describe their installation and testing requirements.
- Size hydromechanical and gravity grease interceptors with practice methods, and explain the requirements of the CSA B481 series and municipal FOG programs.
- Select and size oil, sand, lint, hair, plaster and amalgam separators, and describe their installation, venting and maintenance.
- Calculate booster pump head and pressure zones for tall buildings, and describe pump sets, pressure-reducing stations and backflow protection at the water entry.
- Explain how water and air behave in tall drainage stacks, and apply stack sizing, branch interval, venting, offset and base-of-stack requirements.
- Describe acid waste piping, neutralization, hot waste cooling and other special hospital wastes, and calculate tempering water for hot discharge.
- Identify the medical gases, sources, valves, alarms and outlets in a hospital pipeline system, and explain the role of CSA Z7396.1 and installer certification.
- Describe medical gas installation, brazing under a nitrogen purge, installer tests and independent verification, and correct standing pressure tests for temperature.
- Select backflow protection for fire services, explain the fire department connection, and use hydrant flow test data to find the water supply available.
- Install commercial fixtures, apply water conservation and water quality measures, coordinate with other trades and take part in commissioning and turnover.
