Lesson 1Personal safety, isolating area, and turning off water supplies (individual shutoffs and main shutoff)Learn protective steps for yourself, how to close off the work area, and how to shut individual taps or the main water to stop floods and accidents.
Gloves, eye protection, and kneepadsClearing and securing the work areaLocating fixture shutoff valvesFinding and operating main shutoffLockout and communication practicesLesson 2Testing after repair: slow-open restore, visual inspection for drips, dye test, and monitoring for staining recurrenceLearn to restart the tap after fixing, using slow opening, looking for drips, and dye or paper tests to make sure joints, valves, and cupboard stay dry over time.
Slowly reopening shutoff valvesVisual inspection of joints and seamsUsing tissue or paper to spot weepingDye tests for subtle cabinet stainingShort and long interval rechecksLesson 3Preventive measures and communicating residual risks and recommendation for long-term replacementLook at ways to prevent problems, explain remaining risks to people, and when to suggest planned changes or full tap replacement to avoid repeated leaks and damage.
Routine inspection and cleaning scheduleExplaining remaining leak risks to clientsWhen to suggest hose or valve upgradesPlanning for future faucet replacementDocumenting findings and advisoriesLesson 4Step-by-step faucet disassembly: shutoff, depressurize lines, remove handles, bonnet/nuts, cartridge/valve removalFollow safe steps to take apart a tap, from closing water and releasing pressure to removing handles, covers, and inner parts without damaging threads or surfaces.
Shutting off and tagging water suppliesDepressurizing and draining faucet linesRemoving handles and decorative capsLoosening bonnet nuts and retaining clipsExtracting cartridges or valve stemsLesson 5Systematic diagnosis: identifying faucet type (compression, cartridge, ceramic disc, ball) and locating leak sourceUnderstand how to know tap type, see wear signs, and follow water paths to find the real leak, separating tap problems from supply, drain, or moisture in the cupboard.
Recognizing compression faucet componentsIdentifying cartridge and ceramic disc faucetsBall faucet internals and common leak pointsTracing leaks from spout, body, or baseDifferentiating faucet leaks from supply leaksLesson 6Detecting and locating the cabinet stain source: supply line vs drain vs condensationBuild skills to trace real cause of cupboard stains and wetness, telling high-pressure supply leaks from drain seeps or normal moisture on cold pipes.
Reading stain patterns and drip tracksChecking supply valves and connectionsTesting P-trap and tailpiece jointsIdentifying condensation on cold linesUsing moisture meters and inspection mirrorsLesson 7Repairing small drain leaks: tightening slip joints, replacing washers/gaskets, and sealing techniquesFocus on finding and fixing small drain leaks under sinks, including tightening joins, changing washers and seals, and using sealants while keeping trap straight and sloped.
Inspecting slip joints for mineral tracksTightening nuts without cracking fittingsReplacing beveled and flat drain washersApplying sealant at threaded jointsVerifying trap alignment and fallLesson 8If persistent leakage or corrosion: replacing faucet assembly and steps to select compatible replacementUnderstand when ongoing leaks, rust, or wear make fixing not worth it, and learn to choose and fit a matching new tap for sink holes and water connections.
