Sanitary Installation Course

Lesson 1 • Introduction to Sanitary Systems

Defines sanitary installation scope and distinguishes supply from drainage subsystems. Anchors all subsequent technical content to real-world building contexts.

Lesson 2 • Regulatory and Safety Framework

Covers building codes, health standards, and occupational safety rules applicable to sanitary work. Establishes compliance mindset before hands-on tasks begin.

Lesson 3 • Material Properties and Selection

Compares metals, plastics, and composite pipe materials by pressure rating, corrosion resistance, and cost. Correct material choice prevents premature system failure.

Lesson 4 • Tools and Equipment Overview

Identifies hand tools, power tools, and measuring instruments used in sanitary installation. Proper tool selection reduces errors and improves installation quality.

Lesson 1 • Push-Fit and PEX Connection Methods

Introduces push-fit fittings and PEX crimp, clamp, and expansion methods. These systems accelerate installation in tight spaces and renovation work.

Lesson 2 • Pipe Measurement and Cutting Techniques

Covers accurate measurement, marking, and cutting methods for each pipe material. Precise cuts are the foundation of tight, leak-free connections.

Lesson 3 • Solvent Cementing Plastic Pipe

Details primer and cement selection, cure times, and assembly sequence for PVC and CPVC. Correct technique prevents joint failure under pressure.

Lesson 4 • Threaded and Compression Fittings

Covers pipe threading, thread sealant application, and compression fitting assembly. These mechanical joints are essential for metal pipe and fixture connections.

Lesson 1 • Hot Water System Components

Examines storage tank, tankless, and heat pump water heaters and their installation requirements. Correct heater selection and installation ensures energy efficiency and safety.

Lesson 2 • Backflow Prevention and Cross-Connection Control

Identifies cross-connection hazards and the correct backflow preventer for each risk level. Preventing contamination of potable water is a critical code requirement.

Lesson 3 • Water Supply System Design Principles

Explains pressure zones, flow velocity limits, and demand calculations for supply design. Proper sizing prevents low pressure and water hammer complaints.

Lesson 4 • Hot Water Recirculation Systems

Teaches dedicated return loop and demand-controlled recirculation design. Recirculation reduces water waste and improves user comfort in large buildings.

Lesson 1 • Drain Slope and Pipe Sizing

Covers minimum slope standards, horizontal branch sizing, and stack capacity. Correct slope and sizing prevent blockages and ensure self-cleaning flow.

Lesson 2 • Vent Pipe Routing and Termination

Teaches individual, common, and circuit vent configurations and roof termination rules. Correct venting maintains atmospheric pressure throughout the drainage system.

Lesson 3 • DWV System Fundamentals

Explains gravity drainage principles, fixture unit loads, and the role of venting. Understanding airflow in drainage prevents siphoning and sewer gas entry.

Lesson 4 • Soil Stack and Building Drain Assembly

Covers soil stack assembly, building drain routing, and connection to the public sewer. This section integrates all DWV components into a complete system.

Lesson 1 • Rough-In Dimensions and Layout

Explains how to transfer rough-in specs from fixture sheets to framing and subfloor. Accurate rough-in prevents costly repositioning after walls are closed.

Lesson 2 • Toilet Installation

Details closet flange setting, wax ring sealing, and tank-to-bowl assembly. A correctly installed toilet prevents leaks, rocking, and sewer gas infiltration.

Lesson 3 • Shower and Bathtub Installation

Teaches mortar bed setting, prefab unit leveling, and valve rough-in for tubs and showers. Watertight installation prevents structural damage from hidden leaks.

Lesson 4 • Appliance and Specialty Fixture Connections

Covers dishwasher, washing machine, and floor drain connections including air gap and standpipe requirements. These connections require specific code-compliant configurations.

Lesson 1 • Commissioning and Functional Checks

Teaches systematic fixture-by-fixture commissioning including flow, temperature, and drainage checks. Commissioning confirms the system meets design intent before handover.

Lesson 2 • DWV System Testing Methods

Explains water, air, and smoke test procedures for drainage and vent systems. Each method targets different defect types in the DWV assembly.

Lesson 3 • Diagnosing Common Installation Failures

Identifies root causes of low pressure, slow drains, water hammer, and sewer odors. Systematic diagnosis reduces callback time and improves customer satisfaction.

Lesson 4 • Pressure Testing Water Supply Lines

Covers hydrostatic and air pressure test procedures, acceptable pressure ranges, and leak detection. Testing before wall closure prevents expensive remediation later.

Lesson 1 • Noise Control in Pipe Systems

Covers pipe isolation hangers, acoustic wrapping, and layout strategies to minimise transmission noise. Noise complaints are a leading cause of post-occupancy disputes.

Lesson 2 • Riser Design and Installation

Teaches vertical riser sizing, expansion loop design, and riser clamp spacing. Risers must accommodate thermal movement without stressing joints or structure.

Lesson 3 • Shared Drain Stack Systems

Explains offset stack design, branch interval rules, and aerator fitting use in tall stacks. Shared stacks must handle simultaneous discharge without pressure fluctuation.

Lesson 4 • Pressure Zone Management

Covers pressure-reducing valves, booster pumps, and zone isolation for tall buildings. Uncontrolled pressure variation damages fixtures and creates safety hazards.

Lesson 1 • Pipe Repair and Relining Methods

Covers cut-and-replace, epoxy lining, and pipe bursting as repair strategies. Method selection depends on pipe material, access, and extent of deterioration.

Lesson 2 • Retrofitting Fixtures in Existing Buildings

Addresses rough-in adjustment, wall opening, and connection to existing supply and drain lines. Retrofit work requires adapting to non-standard conditions without full system access.

Lesson 3 • Preventive Maintenance Scheduling

Establishes inspection intervals, cleaning tasks, and component replacement cycles for sanitary systems. Scheduled maintenance extends system life and prevents emergency failures.

Lesson 4 • Condition Assessment of Existing Systems

Teaches visual inspection, pressure testing, and camera inspection to evaluate existing pipe condition. Accurate assessment drives scope definition and cost estimation for renovation projects.
