Sample Haryana BSEH Secondary NSQF Plumbing Practice Questions

Try these sample questions to review concepts for the Haryana BSEH Secondary NSQF Plumbing exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which pipe material is most commonly used for cold-water distribution inside residential buildings in modern Indian plumbing practice because it is light, corrosion-resistant, and easy to join?
A.uPVC or CPVC plastic pipe
B.Cast iron soil pipe only
C.Lead pipe as the default choice
D.Glass-lined clay pipe
Explanation: uPVC/CPVC plastic pipes are widely used for cold (and CPVC often for hot) water systems in Class 10 plumbing training because they resist corrosion, are lightweight, and join with solvent cement or fittings.
2Galvanized iron (GI) pipes are coated with zinc primarily to:
A.Increase the melting point of iron to welding temperatures
B.Reduce corrosion of the steel/iron base metal
C.Make the pipe flexible like a hose
D.Allow solvent-cement joints without threads
Explanation: Zinc galvanizing forms a protective coating that slows corrosion of the iron/steel pipe, extending service life in water systems.
3Which hand tool is primarily used to cut external threads on a GI pipe end before making a threaded joint?
A.Pipe wrench
B.Spirit level
C.Die stock with dies
D.Plumb bob
Explanation: A die stock fitted with the correct die cuts external male threads on metal pipe ends so they can screw into fittings.
4Before cutting threads on a metal pipe, the pipe end should be:
A.Heated until red-hot to soften the metal
B.Coated thickly with solvent cement
C.Bent to 90 degrees to fit the die stock
D.Cut square and lightly reamed/cleaned of burrs
Explanation: A square cut and removal of burrs helps the die start true and produce clean, full-depth threads.
5Which jointing method is standard for uPVC pressure pipe fittings in water supply work?
A.Solvent cement welding of cleaned mating surfaces
B.Lead-oakum caulking only
C.Electric arc welding of the pipe ends
D.Soft soldering with tin-lead alloy only
Explanation: uPVC pressure systems typically use solvent cement on cleaned, dry mating surfaces after trial fit, forming a fused joint.
6Teflon (PTFE) tape on threaded metal pipe joints is applied to:
A.Increase the nominal pipe diameter permanently
B.Seal threads and reduce the risk of joint leaks
C.Replace the need for any pipe support hangers
D.Dissolve rust inside the water main
Explanation: PTFE/Teflon tape or approved thread sealant fills micro-gaps in threads to help create a leak-tight joint.
7When measuring and marking a pipe for cutting, the plumber should mainly ensure that:
A.The mark is made only after the joint is buried in concrete
B.All measurements are taken with a micrometer only
C.The required length accounts for fitting engagement / insertion depth
D.Pipes are always cut 50 mm short of the layout dimension
Explanation: Thread engagement or socket insertion depth must be allowed so the finished centre-to-centre or face-to-face dimension is correct.
8A hacksaw is preferred for cutting many plumbing pipes on site because it:
A.Automatically threads the pipe as it cuts
B.Replaces the need for measuring tools
C.Is used only for cast-in-place concrete formwork
D.Provides controlled cutting with basic PPE and simple setup
Explanation: A hacksaw (or pipe cutter where appropriate) allows controlled cutting of pipe lengths with common workshop setup and PPE.
9Which test is commonly used to check newly installed water supply pipelines for leaks before putting them into service?
A.Hydrostatic pressure test with water under specified pressure
B.Magnetic particle test of every plastic joint
C.Smoke test only, never water pressure
D.X-ray radiography of every residential tap
Explanation: Hydrostatic (water pressure) testing is the standard method to prove water supply pipelines are leak-tight before covering or commissioning.
10During a hydrostatic test of a water line, a falling gauge pressure with no intentional draw-off usually indicates:
A.Perfect airtight joints with no further action needed
B.A leak, open valve, or incomplete isolation of the test section
C.That the pipe diameter has permanently increased
D.That the water has turned into steam automatically
Explanation: Unexplained pressure drop during a closed hydrostatic test signals leakage, an open outlet, or that the section was not properly isolated.

Haryana BSEH Secondary NSQF Plumbing: Suggested Study Strategy

1Learn GI vs PVC/uPVC vs CI pipe uses first—many theory questions start from material selection.
2Memorize common fixtures and traps: basin, WC, urinal, floor trap, P-trap/S-trap, and why traps hold a water seal.
3For tools, match each tool to its job: pipe wrench, die stock, hacksaw, spirit level, measuring tape, and plumber’s vice.
4Practise joint safety: clean threads, use sealant/tape correctly, support pipes, and pressure-test before covering work.
5Link employability units to workshop scenarios: clear customer communication, PPE, water conservation, and basic ICT for job notes.
6Alternate MCQ drills with written short answers so you can explain systems in 2–5 mark BSEH-style responses.
