    Study Notes

    Plumbing Terms and Definitions

    • Relief Vent: A pipe enhancing air circulation between the drainage and venting systems.
    • Residential Full Flow-Through Fire Sprinkler/Standpipe System: Integrates with potable water to provide water flow through all components in one- or two-family dwellings.
    • Residential Partial Flow-Through Fire Sprinkler/Standpipe System: Channels water primarily to the furthest water closet during inactive sprinkler periods.
    • Riser: A vertical pipe extending through at least one full storey for water distribution.
    • Roof Drain: A fitting allowing storm water discharge from the roof into a drainage leader.
    • Roof Gutter: Exterior channel at the slope base of roofs for storm water conveyance.
    • Sanitary Building Drain: Conducts sewage from fixtures to the building sewer.
    • Sanitary Building Sewer: A pipe specifically for sewage transport.

    Plumbing Code Information

    • Backflow Preventers: Assemblies like differential relief valves preventing back-siphonage and protecting potable water.
    • Emergency Floor Drains: Designed to prevent building flooding from pipe or fixture failures.
    • Drainage System: Assembly of pipes and fittings that conveys sewage, clear-water waste, or storm water to a sewer or disposal system.
    • Trap: Device holding liquid to prevent gas passage without impacting liquid flow.

    Water Distribution and Systems

    • Water Service Pipe: Conveys water from public mains or private sources into a building.
    • Water Distribution System: Network of pipes, fittings, and valves delivering water to various fixtures and appliances.

    Fire Protection Systems

    • Class 3 Fire Sprinkler/Standpipe Systems: These systems maintain potable water supplied from the public water supply.

    Venting and Pressure Systems

    • Stack Vent: Connects the top of a stack to vent headers or outside air.
    • Dual Vent: Serves two fixtures, connecting at the opportune junction of trap arms.
    • Wet Vent: A sanitary drainage pipe that also serves as a vent, linking downstream and upstream fixture connections.

    Compliance and Regulations

    • The National Plumbing Code of Canada (NPC) regulates plumbing design and installation across provinces/territories, promoting consistency in plumbing codes.
    • CCBFC: A committee responsible for developing the NPC, consisting of various building and engineering professionals.

    Additional Definitions

    • Storm Water: Water resulting from rainfall or snowfall runoff.
    • Building Drain: The lowest pipe conducting waste products by gravity to the building sewer.
    • Building Sewer: Pipe leading away from the building drain to a public sewer or sewage disposal system.

    Important Considerations

    • Back-siphonage can occur in older buildings if fixtures are improperly filled above designated safety levels.
    • Emergency systems and codes are established to ensure public safety and plumbing integrity during failures.
