01Plumbing Tools, Equipment and Safe Handling
The examiner checks whether you can identify a tool from a description, choose the right tool for a given pipe material, and state the safety rule that travels with it. Questions are scenario-based - for example, "which wrench for a chrome-plated shower arm?" - not plain definitions.
433 words, about 2 min02Pipes, Fittings, Joints and Plumbing Materials
GI (galvanised iron), IS 1239, screwed BSP joints: water supply above ground; strong, but scales and corrodes. uPVC, IS 4985, solvent-cement joints: cold water supply and SWR drainage.
357 words, about 2 min03Water Supply Systems and Domestic Plumbing Layout
Direct (mains-fed): supply taken straight from the municipal main; cheap, but pressure is unreliable and backflow is a risk when the main runs intermittently. Indirect (tank-fed): main → underground sump → pump → overhead tank (OHT) → gravity distribution.
376 words, about 2 min04Sanitary Fixtures, Drainage and Sewerage Systems
Indian or European WC with 3/6 L dual flush, wash basin, kitchen sink, urinal, floor trap (nahani trap), drinking-water fountain. Typical outlets: WC 100 mm, wash basin 32–40 mm, sink 40–50 mm, floor trap 50–75 mm, urinal 32–50 mm.
359 words, about 2 min05Pipe Cutting, Threading, Bending and Jointing Practical Skills
Measure twice, mark clearly, always cut square and deburr. GI/MS: hacksaw with an 18 TPI blade in a rigid frame, light pressure, full strokes.
377 words, about 2 min06Leak Detection, Testing, Repair and Maintenance
Hydraulic pressure test on supply lines: plug all outlets, fill, expel air, raise to about 1.5 times working pressure with a hand test pump (commonly around 10 bar for domestic lines), hold one hour, and record the gauge reading. Drainage: water test - plug the low end, fill the section to a head of about 1 m above its highest point and hold 30 minutes; air or smoke test for stacks, where smoke reveals open joints and missing traps.
408 words, about 2 min07Occupational Health, Safety and Environmental Practices
Physical (cuts, falling tools, sharp sheet metal, noise from core drilling), electrical (wet hands, portable tools, immersion heaters), chemical (solvent cement and primer vapour, flux, drain acids, lead), biological (sewage, drain rods, rodents), ergonomic (lifting cylinders and CI pipes, kneeling), and work-environment (trenches, manholes, ladders, scaffolds). Eliminate (prefabricate off-site), substitute (water-based cleaner, lead-free solder), engineer (local exhaust, guarding, shoring, guard rails), administrate (permit to work, toolbox talk, rotation) - and PPE last.
370 words, about 2 min08Technical Drawing, Estimation, Measurement and Costing
Learn plan, elevation and section, plus the isometric sketch for pipe routes. Line types: continuous thick for visible outlines, dashed for hidden work, chain thin for centre lines; conventional symbols for gate valve, float valve, bib cock, WC, wash basin, floor trap and manhole.
346 words, about 2 min09Employability Skills, Communication and Entrepreneurship
Plumbing sits between the mason, the electrician and the client, so messages must be short and specific: "concealed hot line to basin at 1100 mm, chase ready" beats "pipe done". Confirm instructions in writing - work order, WhatsApp message, or a dated site diary entry - because verbal promises are the commonest cause of payment disputes.
