WBCHSE HS Vocational Plumbing study plan

Identify and name at least 12 pipe fittings (elbow, tee, reducer, union, coupling, cap, cross, bushing, nipple, bend, plug, flange) from a mixed box without reference

Sketch and label the parts of GI, PVC, CPVC and copper pipe jointing methods in a notebook

Demonstrate cutting and reaming a GI pipe square within 2 mm using a pipe cutter and reamer

List five PPE items and three workshop safety rules, and state the correct action for a gas leak and an electrical shock in the workshop

Thread a 15 mm and 20 mm GI pipe with a die set to produce 10 to 12 threads of correct taper without cross-threading

Assemble a leak-free GI joint using thread sealant or teflon tape and test it at line pressure

Make solvent-cemented PVC joints on 25 mm pipe with correct application of primer and cement and the specified curing time

Select the right tool (pipe wrench, adjustable spanner, hacksaw, file, die set, flaring tool) for five given jobs and justify each choice

Identify and explain the function of WC pan, wash basin, sink, floor trap, gully trap, P-trap, S-trap, vent pipe and inspection chamber

Calculate the correct slope for a 100 mm horizontal drain branch over a given run using the 1:40 to 1:60 guidance and state the reason for the slope

Draw a single-line drainage layout for a two-bathroom house showing soil, waste, vent and inspection chamber positions

Explain the purpose of water seal, trap seal depth and anti-siphonage ventilation in your own words

Compare overhead tank, underground sump and direct municipal supply on pressure, contamination risk and cost in a short written table

Size a cold-water distribution pipe run for a three-tap house using fixture unit or demand guidance and record the reasoning

Install a float valve and an air gap in a model overhead tank setup and verify shut-off at the design level

State the recommended free chlorine residual and the standard disinfection procedure for a new storage tank

Locate and repair a concealed leak in a practice line using a listening stick or visual inspection, documenting the steps taken

Replace a leaking tap washer, a float valve and a WC flush siphon mechanism within 20 minutes each

Clear a blocked P-trap and a floor trap and explain the difference between a blockage and a venting fault

Prepare a preventive maintenance checklist covering monthly, quarterly and annual tasks for a household plumbing system

Measure a small bathroom from a sketch and prepare a material take-off listing pipe lengths, fittings, fixtures and consumables with quantities

Price the take-off using current local rates and produce a quotation with labour, material, overhead and a stated margin

Draft a simple work order and a completion certificate template with the fields a customer expects

Explain in writing how to register a small plumbing service business and list three ways to find the first customers

Execute a full small project end to end: layout, cutting, jointing, fixture fixing and pressure testing within the time limit

Inspect your own work against a 10-point quality checklist covering alignment, slope, leak tightness, support spacing and finish

Demonstrate correct use of hand tools and one power tool with the safety guard in place and describe the residual risk

Record the project in a step-by-step log with photographs and a short reflection on what went wrong and how it was corrected

Revise the heaviest domains using a personal error log of every mistake made in weeks 1 to 7 and re-solve each one

Answer at least 60 mixed practice questions across all nine domains under timed conditions and review every wrong answer

Recite the key formulas and rules (slope, tank capacity, trap seal depth, thread count, curing times) from memory

Complete one full mock paper and record the score and the two weakest areas for final revision
