Plumbing tools for an apprentice

A first plumbing kit in buying order, all 38 grouped by when you need them: the day one bag, the first year, later as the work demands, and what your employer is legally required to supply rather than you.

14 are marked essential: have them before your first day.

Part of the full plumbing tools list, 56 tools in 9 groups.

The day one bag 11

Ten or twelve tools, bought properly. Enough to be handed real work rather than watching it.

  • Wheel pipe cutter: A copper pipe cutter with a cutting wheel, two rollers and a knurled adjusting knobEssential

    Wheel pipe cutter

    Cuts copper square with no filings inside the pipe, which is why a hacksaw is not acceptable on a water system. The first tool you will be asked for and the one you will use most.

  • Two adjustable spanners of different sizes with knurled adjusting screwsEssential

    Adjustable spanners

    Two of them, because nearly every joint needs one holding the fitting and one turning the nut. Buy these well: a spanner that flexes rounds the nut and then the job gets much longer.

  • A pair of water pump pliers with an adjustable slip joint and long serrated jawsEssential

    Water pump pliers

    Wide adjustable jaws that grip a plastic trap, a large nut or a pipe. Not gentle, so they belong on things being replaced rather than on chrome that stays visible.

  • A pair of long nose pliers with slim tapering jaws and insulated handlesEssential

    Long nose pliers

    Reaches into a cistern or behind a panel to place a washer or retrieve a dropped clip. In plumbing most of what you need to hold is somewhere your fingers do not fit.

  • Screwdriver set: A set of screwdrivers with different tips and coloured moulded handlesEssential

    Screwdriver set

    Flat, Phillips and Pozidriv in several sizes. Matching the tip to fill the head is what stops it slipping, and most stripped screws are a size mismatch rather than a hard screw.

  • A retractable steel tape measure with a yellow blade, belt clip and locking buttonEssential

    Tape measure

    A 5m tape with a lock. Measure to the fitting shoulder rather than the pipe end and allow socket depth at both ends, which is the mistake everyone makes for the first month.

  • An aluminium spirit level with three glass vials and machined edgesEssential

    Spirit level

    The most underrated tool on the list. Most complaints about finished plumbing are that something is not level or not straight, and getting that right is noticed immediately.

  • Torpedo level: A short magnetic torpedo spirit level with three vials and a yellow bodyEssential

    Torpedo level

    A short magnetic level for a pipe in a confined space. Under a sink or in a joist bay there is rarely room for anything longer, so this is the one that actually gets used.

  • A metal bodied utility knife with a retractable trapezoid bladeEssential

    Utility knife

    Cuts insulation, packaging and thin pipe. Snap the blade off the moment it drags, because a blunt blade needs force and force is how it slips off the work and into you.

  • A black permanent marker pen with the cap offEssential

    Marker pen

    Marks wet, greasy or oxidised pipe where a pencil will not. A mark you cannot see is a cut in the wrong place, which is an expensive way to learn to buy a proper marker.

  • An open top canvas plumbers tool bag with side pockets and a shoulder strapEssential

    Tool bag

    An open top bag or a bucket organiser. Buy this cheaply, because it will get wet, dirty and damaged, and a tidy cheap bag is worth more than an expensive disorganised one.

The first year 11

Added when a job calls for them rather than in advance. You will use everything on this list within twelve months.

  • Lever pipe bender: A lever type copper pipe bender with two long handles and a curved former

    Lever pipe bender

    Bends 15mm and 22mm copper cold, removing two soldered joints per corner. A good one lasts a working lifetime, which makes it a sensible second hand purchase.

  • A handheld plumbers blowtorch with a gas canister and self igniting burner head

    Blowtorch

    Heats a soldered joint to temperature in seconds. A self igniting head is worth the small extra, because juggling a lighter in a joist bay is how things get burnt.

  • Solder and flux: A coil of lead free solder wire beside a small tub of flux paste

    Solder and flux

    Lead free solder and flux paste. Flux dissolves the oxide that forms while you work, and it is not a substitute for cleaning the joint first, which catches everyone once.

  • A basin wrench with a long steel shaft, T handle and swivelling toothed jaw

    Basin wrench

    Reaches the backnut behind a basin, which no ordinary spanner can. The first time you meet a tap change without one you will buy one that evening.

  • Two Stillson pipe wrenches with serrated jaws and long handles

    Pipe wrenches

    For threaded steel pipe, in a pair so one holds and one turns. They last forever and mark everything they touch, so keep them off copper and chrome.

  • Hacksaw: Tensioning knob and pistol grip handle

    Hacksaw

    Cuts steel, threaded rod and large plastic pipe. Keep spare blades, because a blunt hacksaw is the tool most often blamed on the material it is failing to cut.

  • Hex key set: A set of hex allen keys of graduated sizes fanned out from a holder

    Hex key set

    Monobloc taps, shower valves and lockshields all use small hex screws, often 2.5mm or 3mm. Without one you cannot open the fitting at all, however simple the fault is.

  • A pipe deburring reamer with a conical fluted blade and a plastic handle

    Deburring reamer

    Shaves the internal burr off a cut pipe. Skipping it is the commonest cause of a joint that weeps months later, and it is the step that separates careful work from quick work.

  • PTFE tape: Two rolls of PTFE plumbers thread seal tape, one white and one yellow

    PTFE tape

    Wound clockwise onto a male thread so it tightens rather than unwinds. Keep both thin water grade and thicker gas grade, because they are not interchangeable.

  • A black LED head torch with an adjustable elastic headband

    Head torch

    Light where you are looking with both hands free. Almost all plumbing happens in a cupboard, a loft or under a floor, and none of them have light of their own.

  • Notebook and pencil: A small hardback notebook with a pencil resting on it

    Notebook and pencil

    For sizes, fitting names and the order jobs are done in. The cheapest thing on this page and the one that most affects how quickly you stop needing to ask.

Later, as the work demands 8

Not year one purchases. Each becomes obvious the first time a job needs it, and not before.

  • A drum hand drain auger with a metal drum, crank handle and coiled cable

    Hand drain auger

    A spring cable in a drum for clearing a blocked waste. Worth owning once you are sent to unblock things alone, and not before that.

  • A long thin steel radiator spanner with open ends of two sizes

    Radiator spanner

    A long thin spanner for radiator unions tight against the panel. Specialist, cheap, and it makes an awkward job straightforward the moment you have one.

  • A pair of ratcheting plastic pipe shears with a curved blade and red handles

    Plastic pipe shears

    Cut plastic and multilayer pipe square in one squeeze. A copper wheel cutter cracks rigid plastic and a saw leaves swarf, so this is the right tool rather than a convenience.

  • Tap backnut spanner: A cranked tap backnut box spanner, a thin steel tube bent at one end

    Tap backnut spanner

    A thin cranked box sized to standard tap backnuts. Faster than a basin wrench where it fits, and it will not always fit, so it complements rather than replaces one.

  • A set of coiled steel pipe bending springs of graduated diameters

    Bending springs

    Support soft copper while it is bent by hand where a bender will not fit. Twist before withdrawing or the spring grips and stays in the pipe, which is a memorable afternoon.

  • A pair of circlip pliers with fine bent pointed tips and orange handles

    Circlip pliers

    Remove the retaining clips inside cartridges, diverters and shower valves. Without them the clip is prised out with a screwdriver and disappears behind the bath.

  • A click type torque wrench with a calibrated handle scale and square drive

    Torque wrench

    Needed once you work on anything with a stated figure, such as flare joints on a heat pump or air conditioning. A measuring instrument, so it is stored wound right down.

  • Inspection camera

    Inspection camera

    Sees into a void or a duct before you open it. Expensive for an apprentice, and the sort of thing to check is not already in the van before buying.

The employer's responsibility 8

Listed so you know what not to buy. PPE is a legal duty on them, and so is expensive shared plant.

  • A pair of clear lens safety glasses with side shieldsEssential

    Safety glasses

    Required for cutting, grinding and anything under pressure, and supplied by the employer. Marked essential because you must have them, not because you should be paying for them.

  • A pair of grey cut resistant work gloves with coated palmsEssential

    Work gloves

    Cut resistant for sheet and pipe, and long gauntlets for drain work. Employer supplied, and different jobs genuinely need different gloves rather than one pair for everything.

  • A pair of black work knee pads with elastic straps and hard capsEssential

    Knee pads

    Plumbing is a kneeling trade and knee damage is cumulative and permanent. This is the item apprentices most often go without and most regret twenty years later.

  • Ear protection: A pair of over ear protective ear defenders with a padded headband

    Ear protection

    For core drilling, chasing and grinding, all of which are loud enough to cause permanent loss. Supplied by the employer, and hearing damage does not recover.

  • A battery powered press tool for pipe fittings with a crimping jaw

    Press tool

    Crimps press fittings with no flame. Listed here because the cost is well beyond an apprentice wage and it belongs to the business rather than to you.

  • A handheld flue gas analyser with a digital display and a probe

    Flue gas analyser

    Calibrated test equipment for commissioning gas appliances. It needs calibration records, and those belong to the business, which is why the instrument does too.

  • Power tools

    Power tools

    Drills, core drills and cutters, along with their inspection and testing regime. Any firm expecting an apprentice to supply these is telling you something worth listening to.

  • A pipe freezing kit with a gas canister, jacket and hose

    Pipe freezing kit

    Freezes a plug in the pipe so a system need not be drained. Expensive per use, occasional, and firmly a business purchase rather than a personal one.

Buying a first plumbing kit

Buy the day one list properly and add the rest slowly. A large cheap kit is worse than a small good one.

What to turn up with on day one

A small bag with the tools you will be handed jobs for: pipe cutter, adjustable spanners, screwdrivers, pliers, tape measure, spirit level, marker and a knife. That is enough to be useful rather than a spectator.

Buy this list properly. These are the tools you will use every day for years, and the difference between a decent adjustable spanner and a cheap one shows up within a week.

Small bag, good tools
Ten or twelve items bought well beats a forty piece kit of things that flex and slip.
Two adjustable spanners
Almost every plumbing joint needs one holding and one turning. One spanner is half a tool.
Put your name on everything
Tools migrate on site. A punch mark or a paint stripe is how yours come home.
Ask what they want you to bring
Every firm differs, and asking beforehand is a better first impression than guessing.

What the employer supplies

Personal protective equipment is the employer's responsibility, not yours. That means gloves, eye protection, knee pads, ear protection and safety boots where they are required for the work. You should not be buying those out of an apprentice wage.

The same applies to expensive shared plant: press tools, power tools, pipe freezing kits, drain cameras, gas analysers and test equipment. If a firm expects an apprentice to provide those, that tells you something about the firm.

PPE is theirs
Gloves, glasses, ear defenders, knee pads and boots where required. That is a legal duty, not a favour.
Plant is theirs
Press tools, drain cameras, freezing kits, test gear. Nobody starting out should be buying these.
Calibrated equipment is theirs
Anything requiring calibration records belongs to the business, because the records do too.
Ask before you buy anything expensive
You may be buying something already in the van.

Where to spend and where not to

Spend on anything that grips or cuts. A cheap adjustable spanner flexes and rounds nuts, a cheap pipe cutter wanders off square, and a cheap screwdriver cams out and ruins screw heads. In each case the failure damages the work, not just the tool.

Save on anything that only carries or holds: bags, trays, buckets, dust sheets, kneeling pads. They do the same job whatever they cost, and they get lost and damaged fastest.

Buy well
Spanners, pipe cutters, screwdrivers, pliers, levels. The failure mode is a damaged job.
Buy cheaply
Bags, trays, buckets, sheets, pads. Consumable by nature and no worse for being ordinary.
Avoid big sets
Priced on piece count. You will use a third of it, and that third is better bought singly.
Second hand is fine for some
Pipe wrenches, benders and vices last decades. Measuring tools and levels, buy new.

Looking after them

Plumbing tools live in water, and water is what destroys them. Wipe them at the end of the day, keep bare steel oiled, and never put a wet tool in a closed bag overnight.

Keep the bag organised too. The apprentice who can find the right spanner in ten seconds is more useful than the one with a better spanner somewhere in a pile, and that gets noticed quickly.

Dry them daily
A closed bag of wet tools rusts everything in it, including the ones that were dry.
Oil bare steel
An oily rag over cutters, benders and wrenches. Ten seconds, and it doubles their working life.
Organised beats extensive
Finding the right tool fast is a skill people notice. A pile is not a kit.
Replace blades and wheels
A blunt cutter wheel or knife blade makes you look slow when the tool is the problem.

The tools that teach you most

A spirit level and a tape measure. Almost every complaint about finished plumbing is that something is not level, not straight or not where it was supposed to be, and none of that is about skill with a torch.

Also a notebook. Write down pipe sizes, fitting names, the order jobs are done in, and what your supervisor tells you once. Nobody minds explaining something twice; they mind explaining it five times.

Level everything
Radiators, pipe runs, cisterns, brackets. Being visibly straight is most of what a customer judges.
Measure twice
And remember to allow socket depth at both ends, which is the mistake everyone makes for the first month.
Write it down
Sizes, names, sequences. A notebook is the cheapest tool here and the most useful in year one.
Watch the tidy-up
How a good plumber leaves a room is half the job. It is also the part nobody teaches out loud.

Frequently asked questions

What tools does a plumbing apprentice need on day one?
A pipe cutter, two adjustable spanners, a screwdriver set, water pump pliers, long nose pliers, a tape measure, a spirit level, a marker pen, a utility knife and a bag to carry them. Ten or twelve good tools rather than a large cheap kit.
Should my employer provide my tools?
They must provide personal protective equipment, which means gloves, eye protection, ear defenders, knee pads and boots where the work requires them. They should also provide expensive shared plant. Basic hand tools are normally yours, but ask before assuming either way.
How much should I spend on a first plumbing kit?
Less than you think, and on fewer items than you think. A dozen well chosen tools costs a fraction of a large kit and will serve you better. Spend on anything that grips or cuts, and buy the cheapest version of anything that merely carries or holds.
Are plumbing tool kits worth buying?
Usually not. They are priced on piece count, so most of the contents are sizes and types you will not use, and the quality of the pieces you will use is lower than buying those individually. Graduated sets like sockets and hex keys are the exception.
What is the most useful tool for a plumbing apprentice?
A spirit level, for an unobvious reason. Most complaints about finished plumbing are that something is not level, not straight or not where it should be. Getting that right is noticed immediately and it does not depend on any skill you have not learned yet.
Should I buy second hand plumbing tools?
For pipe wrenches, benders and vices, yes, because they have almost nothing to fail and a good old one beats a poor new one. Buy measuring tools, levels and cutters new, since accuracy and a sharp wheel are exactly what wear out invisibly.
How do I stop my tools going missing on site?
Mark every one with a punch mark, a paint stripe or your initials, and count them back into the bag before you leave. Tools migrate on a busy site without anyone intending it, and unmarked tools have no way of finding their way back to you.
What should I add in my first year?
A pipe bender, a blowtorch with solder and flux, a basin wrench, a pair of pipe wrenches, a hacksaw and a set of hex keys. Add each one when a job needs it rather than in advance, and you will spend less and use everything you own.
