Sample WBBSE Madhyamik Vocational Plumbing Practice Questions

Try these sample questions to test your WBBSE Madhyamik Vocational Plumbing exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which hand tool features serrated movable jaws designed specifically to grip and turn cylindrical metal pipes?
A.Stillson pipe wrench
B.Adjustable open-end spanner
C.Flat bench vise
D.Combination pliers
Explanation: The Stillson pipe wrench has floating hook jaws with hardened serrated teeth that dig into smooth round pipe surfaces under leverage, enabling plumbers to tighten or loosen threaded pipes.
2What is the primary function of a pipe reamer after a metal pipe has been cut with a wheeled cutter?
A.To cut external male threads
B.To remove the internal sharp burr or ridge
C.To expand the pipe diameter
D.To apply pipe joint compound
Explanation: Cutting a metal pipe squeezes the metal inward, creating a sharp internal burr. A pipe reamer removes this burr to restore full bore diameter and smooth fluid flow.
3Which tool is ideal for making clean, square cuts on soft copper or plastic tubing without crushing the tube wall?
A.Hacksaw with coarse blade
B.Cold chisel and hammer
C.Wheeled tubing cutter
D.Angle grinder with masonry disc
Explanation: A wheeled tubing cutter rotates around the tube while a sharp cutting wheel is tightened gradually, producing a precise 90-degree square cut without deforming soft wall tubing.
4What tool assembly is used by plumbers to cut external tapered threads on Galvanized Iron (GI) pipes?
A.Tap wrench and taper tap
B.Hacksaw and guide frame
C.Pipe bender and mandrel
D.Die stock and adjustable pipe dies
Explanation: A die stock holds interchangeable pipe threading dies (such as BSPT dies) that cut tapered external threads onto the end of GI or mild steel pipes.
5Which heavy-duty wrench utilizes a wrapped steel roller chain to turn large-diameter pipes where a standard pipe wrench cannot fit?
A.Monkey wrench
B.Strap wrench
C.Basin wrench
D.Chain pipe wrench
Explanation: A chain pipe wrench wraps a high-tensile steel roller chain around large diameter pipes (over 2 inches), engaging jaw teeth against the pipe body to provide immense turning torque.
6Which tool should be selected to tighten a polished chrome-plated brass tap without scratching or marring its decorative surface?
A.Stillson pipe wrench
B.Strap wrench
C.Chain wrench
D.Locking mole pliers
Explanation: A strap wrench uses a flexible fabric or nylon strap that wraps around polished chrome or plastic fittings, applying turning force without metallic teeth that scratch surfaces.
7Which clamping device is mounted on a workbench and equipped with V-grooved jaws to hold pipes securely during cutting and threading?
A.Parallel bench vise
B.Pipe bench vise
C.Woodworking vise
D.C-clamp
Explanation: A pipe bench vise features self-centering V-shaped serrated jaws that securely grip round pipes from top and bottom, holding them immobile during threading, cutting, or reaming.
8What type of bending equipment uses hydraulic pressure to bend mild steel or GI pipes up to 90 degrees without kinking?
A.Spring pipe bender
B.Manual copper bender
C.Blowtorch heating rig
D.Hydraulic pipe bending machine
Explanation: A hydraulic pipe bender uses a hydraulic ram forcing formers against pipe supports to bend heavy-gauge steel and GI pipes smoothly without flattening or kinking.
9Which traditional layout tool consists of a pointed metal weight suspended from a string to verify the exact vertical alignment of vertical soil stacks?
A.Plumb bob
B.Spirit level
C.Try square
D.Water level tube
Explanation: A plumb bob uses gravity to pull a weighted pointed cone straight down, providing a true vertical reference line to ensure vertical drainage pipes and walls are perfectly plumb.
10What tool uses a fluid-filled glass vial with an air bubble to check the gradient slope of horizontal drainage pipes?
A.Micrometer
B.Spirit level
C.Steel measuring tape
D.Feeler gauge
Explanation: A spirit level contains liquid vials with centered air bubbles. When placed along a pipe, the position of the bubble indicates horizontal levelness or exact slope angle.
