Lesson 1System mapping and identifying common piping materials (copper, PEX, PVC) and fixture typesThis section trains learners to map plumbing systems and recognise common piping and fixture materials. Emphasis is placed on identifying copper, PEX, and PVC, tracing branches, and noting fixture types for accurate diagnostics.

Learners distinguish soldered, compression, and flare fittings, determine failure causes, choose repair methods, and confirm success with pressure testing.

Learners practise trap removal, augering, vent checks, flushing, and odour control while avoiding damage to fixtures and maintaining sanitary work practices.

Learners practise installing compression couplings, performing proper soldering, understanding brazing precautions, and conducting pressure tests to verify durable repairs.

Learners compare soldered and mechanical joints, prepare work areas, and prevent damage to existing piping and nearby finishes.

Learners distinguish cartridge, washer, and valve stem designs, identify failure points, and decide when repair or full replacement is appropriate.
Initial visual and functional observationsIdentifying faucet type and componentsCartridge wear, scoring, and seal failureWasher, seat, and valve stem defectsWhen to repair, rebuild, or replace faucetLesson 7Tools and materials for drain clearing (plunger, hand auger, sink trap removal tools, enzyme/biological cleaners)This section reviews essential tools and materials for clearing residential drains. Learners compare plungers, hand augers, and trap tools, and evaluate when to use enzyme or biological cleaners versus mechanical methods.

Learners practise safe shutoff, disassembly, part identification, reassembly, and testing to restore proper operation without damaging finishes.
Isolating water and relieving pressureProtecting finishes and access setupDisassembling handles and trim safelyMatching and installing new partsReassembly, testing, and fine adjustmentsLesson 9Diagnosing slow and smelly kitchen drains (mechanical blockage, trap/vent issues, biofilm buildup)This section focuses on diagnosing slow and smelly kitchen drains. Learners differentiate mechanical blockages, trap or vent issues, and biofilm buildup, then choose appropriate mechanical and cleaning methods to restore flow and control odours.

Learners use cartridge pullers, spanners, and plumber’s grease correctly, select compatible replacement parts, and avoid damage to decorative finishes.

Learners perform pressure and visual checks, use dye for leak detection, record findings, and communicate clearly with residents using standardised templates.
