Lesson 1System mapping and identifying common piping materials (copper, PEX, PVC) and fixture typesThis part teaches trainees to map plumbing setups and spot usual piping and fixture materials. Focus is on recognising copper, PEX, and PVC, following lines, and marking fixture kinds for proper checks.

Trainees learn to tell apart soldered, compression, and flare fittings, find why they fail, pick fix methods, and check with pressure tests.

Trainees do trap removal, augering, vent looks, flushing, and smell control without harming fixtures and keeping clean work habits.

Trainees fit compression couplings, do right soldering, know brazing care, and test pressure to ensure strong fixes.

Trainees compare soldered and push joints, ready areas, and stop harm to pipes and nearby surfaces.

Trainees tell apart cartridge, washer, and valve stem types, spot weak points, and choose fix or full change.

Trainees compare plungers, hand augers, trap tools, and judge when to use enzyme cleaners over hand methods.

Trainees do safe shutoff, take apart, spot parts, put back, and test without harming looks.

Trainees tell blockages, trap or vent problems, and slime build-up apart, then pick right clearing ways to fix flow and smells.

Trainees use cartridge pullers, spanners, and plumber grease right, pick matching parts, and avoid harm to nice finishes.

Trainees do pressure and eye checks, use dye for leaks, note findings, and talk clear to folks with set forms.
