WBBSE Madhyamik Vocational Plumbing study plan

Classify GI, CI, PVC, CPVC, and PPR pipes by composition, pressure rating, and typical use, and record the classification in a comparison table

Identify at least 15 plumbing hand tools and pipe-fitting tools by correct Bengali and English names and state one safe-use rule for each

Demonstrate the correct procedure for cutting and threading a GI pipe, including reamer use and thread dope application

List the personal protective equipment required for threading, soldering, and trench work, and explain the hazard each item controls

Make one solvent-welded PVC joint and one threaded GI joint, then pressure-test both and record the result

Distinguish elbows, tees, reducers, couplings, unions, and bends by function and select the correct fitting for four given layout situations

Identify the parts of a direct and an indirect (overhead tank) water supply system and trace the flow from source to tap

Compare storage tank placement, distribution pipe sizing, and air-gap requirements for a two-storey house

Explain the working principle of a water-seal trap and distinguish P-trap, S-trap, and bottle trap by where each may legally be installed

Differentiate one-pipe, two-pipe, and single-stack drainage systems and state where each is used

Describe the purpose of soil pipe, waste pipe, vent pipe, and anti-siphonage pipe, and sketch a vented branch

Explain the roles of inspection chamber, gully trap, and manhole in a house drainage line

Identify the main parts of a WC, wash basin, and kitchen sink and state the correct fixing height for each

Calculate the correct drain pipe gradient for a given run and explain why self-cleansing velocity matters

Assemble a small mock drainage line with one trap, one junction, and one inspection chamber, and verify fall with a spirit level

Test the assembled line for leakage and record any defect found

Explain the health and environmental risks of a blocked drain and the safe procedure for clearing it

Read a simple plumbing plan and identify pipe routes, fixture positions, and symbols from the drawing

Prepare a single-line isometric sketch of a bathroom water supply and drainage layout

Measure pipe lengths and count fittings from your own sketch and prepare a quantity table

Calculate material cost and labour cost for that layout and prepare a simple abstract of cost

List at least eight common plumbing faults, their visible symptoms, and the correct repair method for each

Demonstrate leak detection on a concealed pipe using visual inspection, pressure testing, and listening methods

Repair a leaking threaded joint and a leaking tap washer, and verify the repair under pressure

Explain a preventive maintenance schedule for a household water supply and drainage system

Write a short CV and a covering note for a plumbing apprenticeship or helper job

Explain workplace rights, wages, safety duties, and grievance procedures relevant to a plumbing worker

Prepare a basic business plan for a small plumbing service, covering tools, capital, pricing, and customer acquisition

Practise answering customer queries and explaining a repair cost estimate clearly

Complete a full mock project: install a tap, a wash basin, and a short drainage run, and test the whole installation

Revise all eight domains using your own notes and solve at least two practice questions per domain

Re-attempt every earlier deliverable that was incomplete or inaccurate and correct it

Time yourself on a full-length mock paper and review every wrong answer
