Grade 10 building construction – Plumbing Tools and Equipment Quiz
1. Which tool is most suitable for gripping and turning round pipes in plumbing work?
A pipe wrench has serrated jaws and an adjustable head designed to grip and turn round pipes; hammers, chisels and spirit levels are not for turning pipes.
2. Which tool is specifically designed to reach and tighten nuts behind washbasins and taps?
A basin wrench has a long handle and swivelling head made to access and tighten the confined nuts behind basins and taps, where ordinary pliers cannot reach.
3. What is the main use of a plumber's snake (drain auger)?
A plumber's snake (drain auger) is used to reach and remove hair, grease and other obstructions from inside drains; it does not measure pressure, tighten fittings, or solder joints.
4. Which tool gives the cleanest, most accurate cut on plastic (PVC) pipes?
A plastic pipe cutter is designed to cut PVC cleanly and squarely; a hacksaw can cut PVC but less neatly, and trowels or files are not cutting tools for pipes.
5. What is the primary purpose of PTFE (Teflon) tape in plumbing?
PTFE tape is wrapped around male threads to provide a better seal and prevent leaks on threaded fittings; it is not used for soldering, solvent welding, or measuring.
6. Which tool is commonly used to solder (braze) copper pipes in plumbing installations?
A blow torch provides the heat required to melt solder so copper joints can be brazed; drills, pipe wrenches and plungers do not provide heat for soldering.
7. Which tool is used to bend small-diameter copper or soft metal pipes without kinking them?
A pipe bender supports the pipe and applies gradual force so copper or soft metal pipes bend smoothly without kinking; other tools listed are not for bending pipes.
8. Which tool is most appropriate for cutting threads on metal pipes at a job site?
A pipe die and threading tool cut precise threads on metal pipes so fittings can be screwed on; hacksaw blades cut only, and screwdrivers or caulking guns cannot create threads.
9. What is the purpose of flux when soldering copper pipe joints?
Flux removes oxides and promotes wetting so solder flows and bonds the metals; it is not a paint, thread sealant, or measuring tool.
10. Which tool should you use to temporarily stop a blocked sink from leaking while you clear the drain?
A plunger creates suction to dislodge blockages in sinks and toilets and can temporarily help clear a drain; basin wrenches or spanners are for fittings, and pipe cutters cut pipes.
11. Which tool is best for tightening or loosening nuts and bolts when their exact size is not known on site?
An adjustable spanner can be adjusted to fit a range of nut and bolt sizes, making it useful on site; a torque wrench requires known sizes and calibration, while hacksaws and plungers are unrelated.
12. Which tool is used to check that a pipe or fixture is horizontal during installation?
A spirit level shows whether a surface or pipe is horizontal (level); a plumb bob checks vertical alignment, and pipe wrenches/cutters do not measure level.
13. Which simple tool is commonly used to check vertical alignment (true vertical) of a wall or pipe?
A plumb bob hangs from a string and uses gravity to show true vertical for walls or pipes; saws, spanners and basin wrenches are not alignment tools.
14. When joining two soft copper pipes without soldering, which fitting is commonly used?
Compression fittings join copper pipes by compressing a ferrule with a nut and do not require soldering; threaded steel couplings and welded flanges are for other materials, and epoxy is not suitable for standard plumbing joints.
15. Which safety equipment should every plumber wear when cutting pipes or using a torch?
Goggles protect eyes from flying particles and sparks, and gloves protect hands from cuts and heat; while rubber boots may be used, goggles and gloves are essential for cutting and torch work.
16. Which measuring tool is best for quickly measuring the length of a pipe on site?
A measuring tape is portable and suitable for measuring pipe lengths on site; calipers measure small diameters, protractors measure angles, and spirit squares are for checking right angles.
17. Which tool would you use to hold a pipe securely while you cut or thread it?
A pipe vice clamps and holds the pipe firmly in place during cutting or threading; plungers or spanners do not provide secure clamping, and a pipe bender is for bending.
18. Which device is used to test a water pipe system for leaks under pressure?
A hydrostatic pressure tester fills the system and applies pressure while a gauge monitors for drops indicating leaks; thermometers, noise meters and spirit levels do not test leaks.
19. Which tool helps remove rusted or rounded nuts and bolts on old plumbing fixtures?
Locking pliers can clamp tightly onto rounded or rusted nuts to provide grip for turning; plungers, tapes and torches do not provide gripping force for nuts.
20. Which tool is used to cut threads on a pipe fitting while it is held in a bench vise?
A die stock and die are used to cut external threads on pipes or fittings; hacksaws and pipe cutters cut rather than thread, and basin wrenches are for tightening fittings.
21. Which material is safest to use for temporary sealing of a leaking threaded joint until it can be properly repaired?
PTFE tape is designed to seal threaded joints temporarily or permanently; cooking oil, sand or paper towels will not seal and may cause more damage.
22. Which hand tool is best to cut small diameter metal pipes in a tight space where a hacksaw cannot swing?
A mini tube cutter clamps around the pipe and rotates to score and cut it in tight spaces; spanners, sledgehammers or plungers are not cutting tools.
23. Which tool is used to remove old sealant and make a pipe surface clean before applying new jointing material?
A wire brush scrapes off old sealant, rust and debris to give a clean surface for new sealant or soldering; plungers and measuring tapes do not clean surfaces.
24. Which piece of equipment is commonly used by plumbers to cut large diameter concrete-encased pipes or chase channels in walls?
Angle grinders with appropriate blades or diamond cutters can cut through concrete and large metal pipes in chase work; basin wrenches, PVC cutters or torches are not suitable for concrete cutting.
25. Which tool would most help you identify the source of a hidden leak inside a wall before opening it up?
A moisture meter detects elevated moisture levels behind surfaces and helps locate leaks without unnecessary demolition; plungers, tape measures and pipe benders cannot detect hidden moisture.
26. What is the primary use of a pipe wrench on plumbing work?
A pipe wrench has serrated jaws designed to bite into rounded pipes so the plumber can grip and turn them; it is not used for cutting, measuring, or sealing.
27. Which tool is best for cutting PVC plumbing pipes cleanly?
A pipe cutter made for PVC produces a neat, square cut with minimal burrs; bolt cutters and hole saws are unsuitable and a plunger is not a cutting tool.
28. Which tool is used to clear deep blockages in drains and sewers?
A plumber's snake (drain auger) extends into the drain to break up or pull out deep blockages that a plunger cannot reach.
29. Which tool is designed to reach and tighten nuts behind a basin or sink tap?
A basin wrench has a long handle and swivelling jaw specifically made to access and turn the confined nuts behind sinks and basins.
30. What is PTFE tape (commonly called plumber’s tape) used for in plumbing?
PTFE tape is wrapped on pipe threads to help seal joints and reduce the chance of leaks; it is not an adhesive or cutting tool.
31. Which personal protective equipment (PPE) is most important to use when soldering copper pipes?
Safety goggles protect your eyes from hot flux, molten solder and sparks during soldering; footwear and headwear do not protect the eyes.
32. Which tool is used to check that a pipe or fitting is perfectly horizontal?
A spirit level shows whether a surface is horizontal or vertical using a bubble; a plumb line checks vertical alignment, not horizontal level.
33. What tool will bend copper tubing without kinking it?
A pipe/tube bender supports the tube while bending so it keeps a smooth curve without kinks; a hammer would damage the pipe.
34. Which tool is most suitable for tightening or loosening hexagonal nuts on plumbing fittings?
An adjustable spanner (adjustable wrench) fits flat-sided (hex) nuts and allows controlled turning; a pipe wrench grips round pipes and is not ideal for hex nuts.
35. Which product is commonly used to join and permanently bond PVC pipe joints?
Solvent cement chemically softens and fuses PVC surfaces to create a permanent joint; solder is for copper and PTFE tape seals threads, not PVC socket joints.
36. Which instrument is used to measure water pressure in a domestic plumbing system?
A pressure gauge measures water pressure in pipes so plumbers can test supply pressure and find leaks or issues; other items do not measure pressure.
37. What tool helps visualise the inside condition of a sewer or drain without digging?
An inspection camera (sewer camera) is pushed into drains to view blockages and pipe condition on a screen, avoiding excavation.
38. Which tool makes a neat cut on copper pipe for soldering work?
A tube/pipe cutter designed for copper produces a smooth, square cut ideal for soldering; bolt cutters and sanders are inappropriate.
39. What is another common name for a plumber’s snake?
A plumber’s snake is often called a drain auger; it is used to break up or pull out obstructions in drains.
40. Which tool is used to scrub and remove rust or scale from inside a metal pipe manually?
A wire or pipe brush scrubs the interior and faces of pipes to remove rust, scale or debris before joining or soldering.
41. Which tool holds a pipe firmly in place while you cut or thread it?
A pipe vice is specifically shaped to grip round pipes securely so cutting, threading or filing can be done safely and accurately.
42. What tool is used to cut screw threads on the end of a metal pipe?
A threading die or pipe threader cuts precise screw threads on pipe ends so threaded fittings can be joined securely.
43. Which plunger type works best for clearing a bathroom sink?
A cup plunger has a simple rubber cup suited to flat sinks and basins; a toilet flange plunger is shaped for toilets and is less effective on sinks.
44. Which tool is used to drill holes in ceramic tiles for pipe or tap fittings?
A diamond or carbide-tipped hole saw is designed to cut through hard ceramic or porcelain tiles cleanly for pipe penetrations.
45. What is a blow lamp used for in plumbing jobs?
A blow lamp (portable torch) provides heat needed to solder copper joints or soften metal for bending; it is not a measuring or cutting tool.
46. Which product is often used instead of PTFE tape to seal and lubricate threaded metal pipe joints?
Pipe joint compound is a paste applied to threads to lubricate and seal them; it is used on metal threads where paste is preferred over PTFE tape.
47. Which tool is the quickest to use for removing a simple toilet blockage at home?
A toilet plunger (with a flange) creates the suction and pressure needed to dislodge common toilet blockages quickly; other tools are not designed for this.
48. What measuring tool gives a precise external diameter of a pipe for selecting fittings?
A vernier caliper measures outside and inside diameters accurately, which helps select the correct-size fittings; a spirit level and hammer cannot measure diameter.
49. Before working on a household water pipe, what important action should a plumber take first?
Turning off the mains water prevents flooding and makes the job safe; starting without isolating the supply risks water damage.
