Maharashtra HSC NSQF Plumber General II study plan

Classify at least 12 pipe types (GI, CI, PVC, CPVC, HDPE, copper) by material, jointing method and typical use without notes

Demonstrate and label the sequence for threading, solvent-welding and compression jointing, listing the tool used at each step

Identify 15 trade tools and state one safety check for each before use

Solve 10 pipe-size and fitting-selection problems by matching nominal bore to fixture demand

Sketch and explain direct and indirect cold-water supply layouts, naming each component in flow order

Compare one-pipe, two-pipe and single-stack drainage systems by venting, cost and where each is suited

Trace a full soil-to-sewer path including traps, vent pipe, inspection chamber and gradient

Calculate required fall for a 12 m drain run at 1:60 and state the resulting invert levels

Explain overhead tank sizing, plumbing of inlet/outlet/washout and overflow, and backflow prevention

Match at least 10 sanitary fixtures and fittings (WC, wash basin, sink, floor trap, bib cock) to their correct trap or fitting

Describe correct installation heights and clearances for common fixtures with reasons

Diagnose three common fixture faults (running cistern, gurgling trap, leaking tap) and name the likely cause and fix

List personal protective equipment and site hazards for plumbing work, and match each hazard to a control

Explain safe handling of gas cylinders, soldering heat sources and confined-space entry

Sequence a hydrostatic pressure test: fill, vent air, pressurise, hold, inspect, record

Describe how to test a drainage line with air or water and interpret a pressure drop

Read a simple plumbing plan and produce a material take-off list for one bathroom with quantities

Apply unit rates to the take-off and compute a total cost including wastage allowance

Draw an isometric sketch of a bathroom plumbing layout from given dimensions

Explain how to measure pipe runs and count fittings accurately for estimation

Diagnose and describe repair steps for 6 faults: burst pipe, leaking joint, blocked drain, faulty float valve, noisy pipe, low pressure

Complete two full-length timed mock papers across all domains and score each

Review every wrong answer and write the correct reasoning for each

Revisit the three weakest domains and re-test with 15 targeted questions each

Confirm final recall of key formulas, gradients, test pressures and fixture heights
