Common Plumbing Tools and What They Do

Adjustable Spanner (Monkey Spanner) 🔧

Used to tighten or loosen nuts and bolts. Good for taps and fittings. Common in Kenyan hardware shops.

Safety tip: choose correct jaw opening; pull spanner towards you (not push).

Pipe Wrench (Stillson Wrench) 🔩

For gripping and turning round pipes (GI pipes). Has serrated jaws that bite into the pipe.

Safety tip: use correct size; hold with two hands and ensure firm footing.

Basin Wrench

Long-reach wrench used under sinks to loosen/tighten tap nuts in tight spaces.

Safety tip: keep fingers clear of jaws when turning.

Hacksaw & Blades 🪚

Cutting metal or plastic pipes. Replace worn blades for clean cuts.

Safety tip: clamp pipe in a vice; wear goggles to protect eyes.

PVC Pipe Cutter / Ratchet Cutter ✂️

Faster, cleaner cuts on uPVC pipes used in drainage and cold-water systems.

Safety tip: cut square and deburr edges before joining.

Plumber’s Tape (PTFE/Teflon Tape) and Pipe Dope

Seal threaded joints to prevent leaks on taps and fittings.

Safety tip: wrap tape in direction of threads; avoid excess.

Plunger & Hand Auger (Drain Snake)

Clear blockages in sinks, toilets and drains. Auger reaches deeper clogs.

Safety tip: use gloves; avoid using chemical drain cleaners with mechanical tools.

Soldering Kit (Blowtorch, Flux, Solder)

Join copper pipes using heat and solder. Often used for hot water lines.

Safety tip: use in ventilated area, wear goggles and heat-resistant gloves, keep water supply off.

Measuring Tape, Spirit Level & Marker

Measure lengths, check alignments and mark cut lines for accurate work.

Safety tip: retract tape slowly to avoid injury.

Note: In Kenya you will commonly see GI (galvanized iron), copper and uPVC (plastic) pipes. Choose tools that match the material.

Safety Measures When Handling Plumbing Tools

Wear PPE: safety goggles, gloves, closed-toe shoes, dust mask (when cutting or soldering), ear protection if noisy.
Isolate water supply: shut main or local stop-cock before starting work. Drain pipes before cutting.
Electric safety: switch off nearby electrical supply if working close to electric fittings or wet areas.
Ventilation: work in a ventilated space when using solvents, adhesives or soldering torches to avoid fumes.
Correct tool for the job: misuse can damage tools and cause injury (e.g., don’t use a pipe wrench on a spanner nut).
Secure work: clamp pipes in a vice when cutting or soldering to prevent slipping.
Keep area clean: remove water, debris and scrap metal to avoid slips and cuts.
Handle chemicals safely: follow instructions for PVC solvent, flux and adhesives; keep away from children and open flames.
Report damaged tools: cracked handles, loose jaws or blunt blades should be tagged and removed from use.

Practical Tasks — Step-by-Step (Use and Apply Tools)

Task A: Replace a Tap Washer (Common household repair)

Tools needed: adjustable spanner, screwdriver, replacement washer, cloth, basin wrench (if space tight).

Turn off the water supply to the tap and open the tap to drain remaining water.
Cover basin with a cloth to prevent small parts dropping in.
Remove handle screw and handle; use spanner or basin wrench to loosen the retaining nut.
Take out old washer, check seat for damage and clean inside of tap.
Fit new washer and reassemble in reverse order. Use PTFE tape on threads if necessary.
Turn water on slowly and check for leaks.

Skills practiced: safe isolation of water, use of spanner/screwdriver, leak testing.

Task B: Cut and Join uPVC Pipe (Drainage)

Tools needed: tape measure, pencil, PVC cutter or hacksaw, file/deburr tool, PVC cleaner & solvent cement, coupler or elbow.

Measure and mark pipe to correct length. Double-check measurements.
Clamp pipe if needed and cut squarely with cutter or hacksaw. Remove burrs with file.
Clean pipe end and inside of fitting with PVC cleaner; apply solvent cement to both surfaces.
Quickly push pipe into fitting with a 1/4 turn and hold for a few seconds. Wipe excess cement.
Allow recommended curing time before testing with water (check manufacturer’s instructions).

Skills practiced: accurate measuring, correct cutting, safe use of adhesives, alignment checking.

Task C: Clear a Blocked Sink (Using Plunger & Hand Auger)

Tools needed: plunger, hand auger, bucket, gloves.

Remove visible debris from the sink strainer. Place bucket under trap if you expect to remove it.
Try plunger first: create seal and pump strongly several times, then pull quickly to dislodge blockage.
If plunger fails, use hand auger: feed cable into drain, rotate handle and push until you feel resistance, then retrieve debris.
Reassemble and run water to check flow. Clean tools and disinfect after use.

Maintaining Plumbing Tools and Equipment

Clean tools after use: remove dirt, solder or PVC cement residue.
Dry and oil moving parts (wrenches, pliers) to prevent rust. Use light machine oil.
Sharpen blades and replace worn hacksaw blades regularly for safe cutting.
Check jaws and handles for cracks or wear; repair or replace damaged tools.
Store tools in a dry, locked toolbox or labeled rack. Keep chemicals in sealed containers and away from tools.
Keep an inventory log: date of purchase, condition, repairs. This helps in school workshops and small businesses.

Why Tools and Equipment Matter

Quality tools make work faster and safer.
Right tools produce reliable, leak-free plumbing that saves water and money.
Good maintenance of tools reduces repair costs and extends life of equipment.
Using proper equipment meets building standards and gives professional results.
Understanding tools helps in getting work in the Kenyan construction market (homes, schools, small businesses).

Suggested Learning Experiences (Practical & Active)

Teacher demonstration: show proper use of spanners, pipe wrenches, seals and PTFE tape. Discuss safety first.
Hands-on stations: students rotate through tasks — change a tap washer, cut and join uPVC pipe, clear a blocked sink.
Group activity: create a tool inventory for a small plumbing job and explain why each is needed (budgeting and selection).
Field visit: visit a local hardware shop or construction site in your town (e.g., Nairobi, Kisumu) to see tools in real use and ask about common local pipe types.
Role-play: one student acts as plumber, another as homeowner; practise asking questions, listing tools, and explaining safety to the customer.
Maintenance workshop: students clean, oil and store a set of tools; keep a maintenance checklist and logbook.
Safety drill: simulate isolating water supply and practicing safe working posture and PPE use.

Assessment Suggestions

Practical test: Replace a tap washer and prove no leak exists (observe SLOs c and e).
Practical test: Cut & join a 50 mm uPVC pipe with correct alignment and no leaks after curing.
Oral quiz: Name tools, describe uses and safety measures (SLOs a & b).
Portfolio: tool maintenance log and short reflection on why tools are important (SLOs d & e).
Peer assessment: students check each other using a checklist (safe tool use, PPE, isolation, correct procedure).
