Lesson 1System mapping and identifying common piping materials (copper, PEX, PVC) and fixture typesDis section train learners fi map plumbin systems an recognize common pipin an fixture materials. Emphasis deh pon identifyin copper, PEX, an PVC, tracin branches, an notin fixture types fi accurate diagnostics.
Reading existing drawings and as-builtsTracing supply and drain piping routesIdentifying copper, PEX, PVC, and othersCataloging fixture and trim typesCreating and updating field system mapsLesson 2Diagnosing and repairing a visible leak at a copper joint (solder vs. compression vs. flare fittings, pressure testing)Dis section teach diagnosis an repair a visible leaks at copper joints. Learners distinguish soldered, compression, an flare fittins, determine failure causes, choose repair methods, an confirm success wid pressure testin.
Identifying joint type and access limitsCommon causes of copper joint failureResoldering and reflowing existing jointsCompression and flare repair optionsPressure testing repaired copper linesLesson 3Step-by-step drain cleaning and deodorizing (trap removal, augering, vent inspection, flushing and deodorizing)Dis section detail a structured workflow fi cleanin an deodorizin drains. Learners practice trap removal, augerin, vent checks, flushin, an odor control while avoidin damage to fixtures an maintainin sanitary work practices.
Safety, PPE, and work area preparationRemoving and inspecting sink and tub trapsUsing hand augers and small drum machinesVerifying vent function and airflowFlushing, sanitizing, and deodorizing drainsLesson 4Step-by-step copper joint repair options (compression coupling install, soldering technique, brazing precautions, pressure test)Dis section present stepwise copper joint repair options. Learners practice installin compression couplins, performin proper solderin, understandin brazin precautions, an conductin pressure tests fi verify durable repairs.
Surface cleaning and pipe end preparationInstalling and tightening compression jointsSoldering technique and heat controlBrazing precautions near combustiblesPressure testing and leak verificationLesson 5Tools and materials for copper joint repair (propane torch, solder, flux, replacement fittings, compression coupling, pipe cutter)Dis section explain how fi select, inspect, an safely use tools an materials fi copper joint repair. Learners compare soldered an mechanical joints, prepare work areas, an prevent damage to existin pipin an nearby finishes.
Selecting propane torch and fuel typesLead-free solder and compatible flux useChoosing fittings and compression couplingsPipe cutters, reamers, and deburring toolsHeat shields, fire safety, and work prepLesson 6Diagnosing a dripping bathroom sink faucet (observational checks, cartridge vs. washer vs. valve stem issues)Dis section teach a systematic approach fi diagnosin drippin bathroom sink faucets. Learners distinguish cartridge, washer, an valve stem designs, identify failure points, an decide when repair or full replacement deh 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)Dis section review essential tools an materials fi clearin residential drains. Learners compare plungers, hand augers, an trap tools, an evaluate when fi use enzyme or biological cleaners versus mechanical methods.
Types of plungers and proper selectionHand augers and cable handling basicsTrap removal tools and safe useEnzyme and biological cleaner selectionTool care, cleaning, and storageLesson 8Step-by-step faucet cartridge or washer replacement procedure (shutoff, disassembly, replace, reassemble)Dis section provide a detailed procedure fi faucet cartridge an washer replacement. Learners practice safe shutoff, disassembly, part identification, reassembly, an testin fi restore proper operation widout damage to 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)Dis section focus pon diagnosin slow an smelly kitchen drains. Learners differentiate mechanical blockages, trap or vent issues, an biofilm buildup, then choose appropriate mechanical an cleanin methods fi restore flow an control odors.
Interviewing occupants about drain historyChecking traps, baffles, and disposer outletsTesting venting and air admittance valvesLocating grease and food-related blockagesBiofilm removal and odor control methodsLesson 10Tools and materials for faucet repair (cartridge removal tools, adjustable wrenches, plumber's grease, replacement cartridges/washers)Dis section cover specialized tools an materials fi faucet repair. Learners use cartridge pullers, wrenches, an plumber’s grease correctly, select compatible replacement parts, an avoid damage to decorative finishes.
Cartridge pullers and specialty toolsAdjustable wrenches and proper sizingUse of plumber’s grease on sealsSelecting cartridges, washers, and seatsProtecting finishes during tool useLesson 11Post-repair plumbing testing and documentation (pressure/visual checks, leak detection with dye, resident notification templates)Dis section cover how fi verify plumbin repairs an document results. Learners perform pressure an visual checks, use dye fi leak detection, record findins, an communicate clearly wid residents usin standardized templates.
Static and dynamic pressure testing stepsVisual leak checks at joints and fixturesDye testing traps, bowls, and tanksRecording readings, photos, and notesResident notification and sign-off forms
