Haryana BSEH Senior Secondary NSQF Plumbing study plan

Classify the four main pipe materials (GI, PVC, CPVC, copper) by pressure rating, temperature limit and typical use, and write a one-line justification for each choice

Thread a 15 mm and a 20 mm GI pipe with a die head, then check the thread with a thread gauge and record the number of imperfect threads

Bend a 15 mm copper or PVC pipe to a 90-degree offset and verify the bend radius and alignment with a try square

Explain the difference between BSP, NPT and metric threads and state where each appears on fittings used in Indian plumbing

List the standard pipe fittings (elbow, tee, reducer, union, coupling, nipple, cap, bend) and match each to a sketch of its position in a run

Assemble a 6-joint GI line using tees, elbows and a union, applying jointing compound or PTFE tape correctly and tightening to a leak-free state

Join a PVC line with solvent cement, describing surface preparation, cement application and curing time before pressure testing

Compare compression, push-fit and solvent-weld joints on cost, skill needed and repairability, and pick the right one for three given site situations

Identify the common causes of joint failure (over-tightening, dirty threads, wrong cement, no primer) and state the correction for each

Read a fitting catalogue page and extract size, pressure class and end connection for five fittings

Draw a single-line diagram of a two-storey house drainage system showing soil pipe, waste pipe, vent stack, trap and inspection chamber

Distinguish soil, waste and vent pipes by function and state the minimum diameter rule for each in a small dwelling

Explain the purpose of a water seal and a trap, and calculate the trap seal depth needed to resist siphonage in a given layout

Describe the causes of self-siphonage, induced siphonage and back pressure, and list three layout changes that prevent them

State the slope requirements for a 100 mm and a 50 mm drain branch and show the fall over a 6 m run

Trace the path of water from overhead tank to a tap, naming every component (ferrule, ball valve, distribution pipe, stop cock, tap) in order

Size a distribution branch for two bathrooms and one kitchen using fixture unit counts and a standard pipe sizing table

Explain direct and indirect (pumped and gravity) supply systems and choose the right one for a two-storey home with low mains pressure

Install and adjust a float valve in a storage tank and set the overflow and washout arrangement correctly

Position and fix a wash basin, water closet and kitchen sink at correct heights and with correct trap and connection points

Calculate storage tank capacity for a family of five using per-capita demand and one day of backup

Design a venting arrangement for a bathroom group and check each fixture trap against the vent distance limit

Explain how an inspection chamber, gully trap and intercepting trap fit into a house-to-sewer connection and sketch the sequence

Identify the causes of foul smell, gurgling and slow drainage in a given layout and propose a fix for each

State the testing procedure for a drainage line (water test and air test) and the acceptance criteria

Draw a plan and an isometric of a toilet and bathroom showing pipe routes, sizes and fixture positions to a stated scale

Take off quantities from your own drawing for pipe, fittings, valves and fixtures, and prepare a priced bill of quantities

Estimate labour and material cost for a bathroom plumbing job and add a realistic overhead and profit margin

List the personal protective equipment needed for threading, solvent welding, working at height and confined space entry, and state when each is mandatory

Describe safe handling and storage of PVC solvent cement, LPG torch work and pipe-cutting tools, and state the first-aid step for cement in the eye

Perform a pressure test on a small line at 1.5 times working pressure, record the gauge reading over 30 minutes and interpret any drop

Locate a simulated concealed leak using acoustic and isolation methods and record the method that worked

Write a repair procedure for a leaking GI threaded joint, a cracked PVC socket and a dripping float valve

Describe the safe procedure for entering a manhole or septic tank, including gas testing, ventilation and standby person duties

Prepare a preventive maintenance schedule for a household plumbing system covering tanks, valves, traps and exposed pipes

Prepare a quotation for a small plumbing contract that states scope, exclusions, payment terms and warranty

Explain the documents needed to start a small plumbing business, including GST registration, Udyam registration and basic bookkeeping

Answer customer-complaint scenarios on delay, rework and cost overrun using a professional response structure

Revise the whole syllabus by re-attempting the weakest topics from weeks 1 to 7 and logging scores per domain

Take two full-length timed mock tests and review every wrong answer against the source topic
