    Compares copper, PVC, CPVC, PEX, and galvanised steel across key performance factors. Provides the material knowledge base for all installation chapters.

  • Lesson 3 • Pipe Sizing and Flow Calculations

    Introduces diameter selection based on fixture units, flow rate, and pressure drop. Ensures students size pipes correctly before cutting or installing any material.

  • Lesson 4 • Fittings, Valves, and Connectors

    Covers elbows, tees, couplings, unions, and shutoff valves and their installation contexts. Connects fitting selection to system design decisions made in Chapter 1.

Chapter 3See details

Pipe Cutting, Joining, and Connection Techniques

    Teaches pipe threading, thread tape application, and pipe dope use for threaded joints. Completes the joining skills set needed for gas and steel pipe work.

  • Lesson 2 • Soldering Copper Pipe Joints

    Covers flux application, torch technique, solder flow, and joint inspection for copper. Soldering is the foundational joining skill for copper supply systems.

  • Lesson 3 • Solvent Welding PVC and CPVC Pipe

    Explains primer application, cement selection, and cure times for plastic pipe joining. Builds on cutting skills to produce structurally sound plastic connections.

  • Lesson 4 • Mechanical and Compression Connections

    Covers push-fit, compression, and crimp fittings used with PEX and copper tubing. Provides tool-free and tool-assisted joining options for varied field conditions.

  • Lesson 5 • Measuring and Cutting Pipe Accurately

    Teaches measurement techniques, allowances for fittings, and proper cutting tool use. Accurate cuts are the prerequisite for every joining method covered in this chapter.

Chapter 4See details

Water Supply System Installation

  • Lesson 1 • Water Heater Installation and Connection

    Covers tank and tankless water heater connections, expansion vessels, and relief valves. Integrates supply system knowledge with appliance-level installation requirements.

  • Lesson 2 • Rough-In Supply Lines to Fixtures

    Guides students through running hot and cold branches to sinks, toilets, and showers. Applies all joining techniques from Chapter 3 in a realistic installation sequence.

  • Lesson 3 • Planning and Laying Out Supply Lines

    Covers route planning, stud drilling, pipe support spacing, and code-required clearances. Proper layout prevents costly rework during rough-in and finish stages.

  • Lesson 4 • Main Shutoff and Meter Connection

    Explains main shutoff valve types, meter bypass procedures, and service entry requirements. Establishes the starting point of every residential supply system.

  • Lesson 5 • Pressure Testing the Supply System

    Teaches hydrostatic and air pressure testing procedures and acceptable pressure thresholds. Validates all supply work before walls are closed and inspections are scheduled.

Chapter 5See details

Drain, Waste, and Vent System Installation

  • Lesson 1 • DWV System Testing and Inspection

    Covers water and air ball test methods, smoke testing, and common inspection failures. Validates the entire DWV system before concealment and final inspection.

  • Lesson 2 • Vent Stack and Branch Vent Installation

    Guides installation of main vent stacks, branch vents, and roof penetration flashing. Proper venting maintains trap seals and allows drain lines to flow freely.

  • Lesson 3 • Installing Drain Lines with Correct Slope

    Covers slope measurement, pipe hanger placement, and hub-and-spigot vs. no-hub connections. Correct slope prevents clogs and is the most inspected element of DWV work.

  • Lesson 4 • DWV System Design Principles

    Explains gravity flow, slope requirements, and vent-to-drain relationships in DWV design. Provides the conceptual framework for all drain and vent installation work.

  • Lesson 5 • Trap Installation for Every Fixture
