Sanitary Plumbing Course

Lesson 1 • Tools and Personal Protective Equipment

Identifies hand tools, power tools, and PPE required for sanitary plumbing work. Proper selection and care of equipment are emphasised throughout.

Lesson 2 • Regulatory Framework and Codes

Introduces the structure of plumbing codes and inspection requirements. Students understand how compliance is verified and enforced on job sites.

Lesson 3 • Workplace Safety Fundamentals

Addresses hazard identification, safe work practices, and emergency procedures on plumbing sites. Builds a safety-first mindset before hands-on training begins.

Lesson 4 • Pipe Materials and Fittings

Surveys pipe materials used in sanitary systems and their appropriate applications. Students match material properties to installation conditions.

Lesson 1 • Pipe Sizing for Drainage

Applies fixture unit totals to select correct pipe diameters for branches and stacks. Sizing tables and interpolation methods are practised.

Lesson 2 • Slope and Grade Requirements

Defines minimum and maximum slope values for horizontal drainage pipes. Students calculate and verify grade using levels and laser instruments.

Lesson 3 • Fixture Units and Load Calculations

Introduces the fixture unit method for quantifying drainage loads. Students calculate total fixture unit values for residential and commercial layouts.

Lesson 4 • Drainage Layout and Routing

Covers strategies for routing drains through floors, walls, and slabs efficiently. Students produce dimensioned drainage layout sketches.

Lesson 1 • Vent Pipe Sizing and Routing

Applies sizing rules to vent branches and stacks based on drainage load and developed length. Routing constraints through walls and roofs are addressed.

Lesson 2 • Testing Vent and Trap Systems

Introduces smoke, air pressure, and water tests used to verify vent and trap integrity. Students perform and document each test method.

Lesson 3 • Function and Importance of Venting

Describes how air circulation through vent pipes protects trap water seals. Students connect venting failures to health hazards and code violations.

Lesson 4 • Types of Vent Configurations

Surveys individual, common, wet, and circuit vent arrangements and their code conditions. Students select the appropriate vent type for given fixture layouts.

Lesson 1 • Pipe Hangers and Support Systems

Specifies hanger types, spacing intervals, and fastening methods for horizontal and vertical runs. Correct support prevents sagging and joint stress.

Lesson 2 • Mechanical and No-Hub Joints

Teaches installation of no-hub couplings, compression joints, and push-fit connectors. Students torque couplings to specification and verify alignment.

Lesson 3 • Cutting and Preparing Pipe

Covers correct cutting methods for plastic, cast iron, and copper pipe. Proper deburring and end preparation prevent joint failures.

Lesson 4 • Penetrations and Sleeve Installation

Addresses fire-stopping, waterproofing, and sleeve requirements where pipes pass through walls and slabs. Students install sleeves and approved fire-stop materials.

Lesson 1 • Toilet and Urinal Installation

Covers closet flange setting, wax ring sealing, and bowl-to-tank assembly for toilets. Urinal carrier and spud connection procedures are also addressed.

Lesson 2 • Lavatory and Sink Installation

Details wall-hung, pedestal, and undermount lavatory mounting methods and drain assembly. Students connect P-traps and verify trap arm alignment.

Lesson 3 • Shower and Bathtub Drain Systems

Explains shower pan liner installation, drain body setting, and tub waste-and-overflow assembly. Waterproofing integration is emphasised at each step.

Lesson 4 • Rough-In Dimensions and Layout

Establishes how to read fixture rough-in sheets and transfer dimensions to the structure. Accurate layout prevents costly repositioning after concrete or drywall is placed.

Lesson 1 • As-Built Documentation

Teaches how to record deviations from design drawings and produce accurate as-built records. Proper documentation supports future maintenance and renovation work.

Lesson 2 • Final Inspection and Punch List

Covers the final inspection scope including fixture operation, trap priming, and cleanout access. Students create and resolve punch lists before sign-off.

Lesson 3 • Rough-In Inspection Preparation

Identifies what inspectors verify at the rough-in stage before walls are closed. Students compile checklists and correct deficiencies before scheduling inspections.

Lesson 4 • Air and Water Pressure Testing

Details procedures for pressurising drainage and vent systems to detect leaks. Students set up gauges, hold pressure, and interpret results.

Lesson 1 • Repairing Leaking Joints and Pipes

Addresses repair methods for cracked pipes, failed joints, and corroded fittings in sanitary systems. Students perform repairs with minimal system downtime.

Lesson 2 • Preventive Maintenance Programmes

Guides students in developing scheduled maintenance plans for commercial sanitary systems. Frequency, scope, and record-keeping practices are defined.

Lesson 3 • Trap and Vent Maintenance

Explains how to service, clean, and replace traps and verify vent system integrity during maintenance visits. Trap primer systems are also serviced.

Lesson 4 • Clearing Blockages and Obstructions

Covers manual and mechanical methods for clearing stoppages in fixture drains and building drains. Students select the correct tool for each blockage type.

Lesson 1 • Grease Interceptor Systems

Covers sizing, installation, and maintenance of grease interceptors for food service facilities. Students calculate interceptor capacity and establish cleaning schedules.

Lesson 2 • Healthcare and Laboratory Drainage

Addresses special drainage requirements for clinical sinks, acid waste systems, and steriliser connections. Material compatibility and infection control are emphasised.

Lesson 3 • Sustainable Drainage Practices

Introduces water-efficient fixtures, grey water reuse, and low-impact drainage design strategies. Students evaluate sustainability trade-offs in sanitary system selection.

Lesson 4 • High-Rise Drainage Considerations

Covers pressure zone management, offset stacks, and sovent systems used in tall buildings. Students address hydraulic shock and noise control in high-rise drainage.
