20 Must-Have Tools Needed for a Plumbing Apprenticeship

Starting a plumbing apprenticeship is exciting and expensive in equal measure, and the first question every new apprentice asks is which tools needed for plumbing apprenticeship they actually need to buy. The honest answer is smaller than the tool store would like you to believe. Most apprentices need about twenty tools to handle the work they will actually be given in their first year: basic wrenching, cutting pipe, clearing drains, and assisting a journeyman on installs. The expensive specialty tools, the pro drain machines, the inspection cameras, and the press tools, belong to the company or the journeyman, and you will get to use them long before you need to own them. This guide lists the twenty tools every apprentice plumber should own in 2026, what each one does, what to spend on it, and what to skip until later. For the homeowner version of this list, see our essential plumbing tools for homeowners guide, and browse the full plumbing tools hub for deeper guides on individual tools.

What an Apprentice Actually Needs on Day One

Before you buy anything, ask your employer or your journeyman what the company provides and what it expects you to bring. Every shop is different. Some companies provide all power tools and specialty equipment and expect apprentices to bring only hand tools. Others expect apprentices to arrive with a full basic kit. Some union programs publish a required tool list, and buying from that list first is the smartest move you can make, because it guarantees you will not waste money on something the shop already owns. If no list exists, the twenty tools in this guide are the safe default, and they cover the work a first-year apprentice is actually assigned: carrying material, cutting and prepping pipe, threading and tightening fittings, clearing simple clogs, and cleaning up after the journeyman.

There is also a mindset point worth making early. Apprenticeship is a four to five year learning process, and your tool collection will grow with your skills. The apprentice who shows up on day one with a 2,000 dollar tool setup and no idea how to use it impresses nobody. The apprentice who shows up with a modest, well-chosen kit, keeps it clean and organized, and asks good questions about how each tool is used will earn trust fast. Buy tools as your work demands them, not before. A tool you buy because a YouTube video recommended it and then never use is money sitting in a toolbox. A tool you buy because your journeyman asked you to fetch one three times this week is money well spent.

Quality matters, but it matters unevenly. Some tools earn their price through daily hard use, and some do not. Wrenches and pipe cutters are used every day and take real force, so buy the best you can afford there. A tape measure, a level, and a utility knife are consumables that get lost, dropped, and replaced, so mid-range is fine. The budget section at the end of this guide breaks the spending down tool by tool, and the total will surprise you: a complete, respectable starter kit is achievable for the price of a few days of apprentice wages, and it will last you well into your second year if you take care of it.

Wrenches: The Core of the Trade

Five of the twenty tools are wrenches, and that is no accident. Wrenching is the core physical skill of plumbing, and the right wrench for the job is the difference between a fitting that seals and a fitting that leaks or a nut that rounds off. Tool 1 is a 14-inch pipe wrench, the workhorse of the trade. It grips round pipe and fittings with hardened teeth, and a 14-inch wrench handles most residential pipe up to two inches in diameter. Buy a name brand, either RIDGID or Reed, because the teeth on a cheap pipe wrench dull fast and a dull pipe wrench slips, which rounds fittings and skins knuckles. Expect to pay 30 to 45 dollars in 2026.

Tool 2 is a 10-inch pipe wrench, the smaller partner to the 14-inch. It fits into tight spaces under sinks and behind toilets where the big wrench cannot go, and it is the wrench you will reach for on half-inch and three-quarter-inch pipe. Tool 3 is an adjustable wrench, a 10-inch or 12-inch Crescent-style wrench, used on hex nuts, supply line connections, and faucet fittings where a pipe wrench would damage the finish. Tool 4 is a basin wrench, the long-handled wrench with a pivoting jaw that reaches up behind a sink to tighten faucet mounting nuts. It is a tool that looks strange, costs about 15 to 25 dollars, and saves an hour of frustration every time a faucet needs to be installed or removed. Tool 5 is a set of tongue-and-groove pliers, often called Channellocks after the leading brand, in two sizes: a 10-inch and a 12-inch. These grip, turn, and hold almost anything, from slip-joint nuts to drain assemblies, and they are the most versatile pliers in a plumber kit. Buy the real Channellock brand if you can. The jaw design is better, and the pliers last for years.

Two more gripping tools round out this group and bring the wrench count to seven if you count them, but they belong in the cutting and joining section for clarity. The point here is that wrenches are where your money should go first. A 100-dollar investment in two good pipe wrenches, a basin wrench, and a pair of Channellocks will serve you every single day of your apprenticeship. Keep the jaws clean, wipe the tools down at the end of the day, and never use a pipe wrench on a finished chrome fitting, where it will leave teeth marks. That last rule is one your journeyman will thank you for learning early.

Cutting and Joining Tools

Tool 6 is a tubing cutter for copper pipe, the small wheel cutter that makes a clean, square cut on copper tube. A clean cut matters because a ragged cut will not seal in a soldered or press joint, and the tubing cutter is the tool that guarantees it. A good cutter costs 15 to 30 dollars, and the RIDGID and Milwaukee models are the standard choices. Tool 7 is a PEX cutter, a scissor-style cutter that makes a clean square cut on PEX tubing without crushing it. It costs 15 to 25 dollars, and it is essential now that PEX is the dominant residential water line material in new construction. Our guides to how to cut copper pipe and how to cut PEX pipe cover the technique for both.

Tool 8 is a hacksaw with spare blades, for cutting ABS and PVC drain pipe, cutting metal pipe in a pinch, and cutting anything the tubing cutter cannot reach. Buy a high-tension hacksaw frame and keep a pack of 18-teeth and 24-teeth blades in the box. Tool 9 is a deburring tool or a utility knife for reaming and cleaning cut pipe ends. A burr left inside a copper pipe will restrict flow and can cause turbulence that erodes the pipe over time, and a burr on a plastic pipe will prevent a solvent-welded joint from seating fully. A simple handheld deburring tool costs under 10 dollars and earns its place in every kit. Tool 10 is a propane torch kit for soldering copper, including the torch head, a striker, solder, and flux. Soldering is a core apprentice skill, and your own torch lets you practice at home. A basic torch kit costs 40 to 70 dollars in 2026. Practice on scrap copper until your joints are clean and consistent before you solder a joint that will be hidden inside a wall.

Tool 11 is a set of screwdrivers, both flathead and Phillips, in two sizes each, plus a nut driver set if your budget allows. Screwdrivers are used constantly in plumbing: removing access panels, adjusting fixtures, opening cleanouts, and assembling equipment. A single multi-bit screwdriver with interchangeable bits covers most of this work and takes up less space in the toolbox. Tool 12 is a utility knife with a retractable blade and a pack of spare blades, used for cutting insulation, opening boxes, trimming pipe, and a dozen other daily tasks. It is a cheap tool, and it is also one of the most dangerous in the kit if it is dull, so keep fresh blades in it and always cut away from your body.

Drain and Inspection Tools

Tool 13 is a hand-crank drain auger, a 25-foot snake for clearing fixture drains. Every apprentice will be sent to clear a clogged sink or tub in their first months, and the hand auger is the tool for it. A decent one costs 25 to 45 dollars, and the guidance in our best drain cleaning tools guide applies directly: spend toward the upper end of the range for better cable quality, because a cheap cable kinks on its first real clog. Tool 14 is a cup plunger and a flange plunger, one for sinks and tubs and one for toilets. They cost about 10 dollars each, and they are the first tool you reach for on any clog. Tool 15 is a closet auger, the short snake with a protective guide tube for clearing toilet clogs without scratching the porcelain. It costs 30 to 55 dollars, and it is a tool that pays for itself the first time it saves a toilet from being pulled.

Tool 16 is a flashlight, and it deserves its place on this list more than most apprentices expect. Plumbing work happens in dark basements, crawl spaces, attics, and under sinks, and a bright, rechargeable flashlight or a headlamp is the difference between seeing the leak and guessing at it. A good headlamp costs 20 to 40 dollars and keeps both hands free, which is exactly what you want when you are working under a sink. Buy a headlamp rather than a handheld flashlight if you can only buy one. Your hands are your most valuable tools, and a headlamp keeps them available. A small inspection mirror on a telescoping handle is a useful companion for the flashlight, letting you see behind pipes and into tight spaces, and it costs under 10 dollars.

Measuring, Testing, and Safety Gear

Tool 17 is a 25-foot tape measure, the measuring tool you will use dozens of times a day. Buy a sturdy one with a wide blade that stands out without collapsing, and expect to pay 15 to 25 dollars for a good one. Tool 18 is a torpedo level, the short 9-inch level that checks whether a pipe has the correct slope and whether a fixture is level. Drain pipe slope is critical: too little slope and the drain will not flow, too much slope and the water outruns the waste. A torpedo level costs 10 to 20 dollars, and it is one of those tools that separates a professional installation from a guess. Tool 19 is a basic digital multimeter, for testing water heater elements, checking whether a circuit is live, and diagnosing pump problems. A 25 to 40 dollar CAT III rated meter is enough for an apprentice, and learning to use it safely is a skill that will serve you for your entire career. Read our guide to how plumbers use multimeters for the full rundown of what the meter does.

Tool 20 is safety gear, and it counts as a tool because it protects the tools you cannot replace: your eyes, your hands, and your hearing. Safety glasses, work gloves, knee pads, and hearing protection for power tool work are the minimum. Safety glasses cost 10 to 15 dollars and should be worn whenever you are cutting, soldering, or working overhead. Gloves protect against sharp pipe edges, hot surfaces, and drain waste, and a 15-dollar pair of good work gloves lasts for months. Knee pads are the item apprentices skip and regret: plumbing is a kneeling trade, and a 20-dollar pair of knee pads will save your knees over a forty-year career. Buy them early and wear them every day.

Tool Storage and Organization

Owning twenty tools is only half the job. Keeping them organized, clean, and ready is the other half, and it is the half that journeymen notice. A tool bag is the standard choice for an apprentice: a soft-sided bag with pockets and compartments that holds the hand tools you use every day, costs 40 to 80 dollars for a good one, and is easy to carry into a house without scratching floors. A rolling tool box is better for a larger collection, but it is heavy and awkward on stairs, so most apprentices start with a bag and add a box later. Whatever you choose, the rule is simple: every tool has a place, and it goes back to that place at the end of every job. A tool left on a job site is a tool lost, and a lost tool is money out of your pocket.

Organization also means maintenance. Wipe your wrenches down at the end of the day, oil the moving parts occasionally, keep your pipe wrench teeth clean, and replace a worn tape measure or a dull hacksaw blade before it costs you a mistake. Label your tools with your name or initials. On a job site with three apprentices, tools get mixed up, and a labeled tool comes back to you. Keep an inventory list of your tools, with the purchase date and price, so you know what you own and what it would cost to replace. Some apprentices photograph their toolbox once a month for insurance purposes, which is a smart habit if your tools travel with you every day. A clean, organized kit signals to your journeyman that you take the trade seriously, and that signal matters as much as any single tool in the bag.

Starter Kit Budget and Buying Advice

The full twenty-tool starter kit costs roughly 350 to 600 dollars in 2026, depending on the brands you choose and whether you buy everything at once or spread the purchases over your first few months. The table below gives realistic prices for each tool, and it is worth studying before you go shopping. The most important buying advice is to buy in order of use: wrenches and cutters first, because you will use them on day one, then drain tools, then measuring and safety gear. Do not buy everything in a single trip unless you have to. Spread the purchases over your first month, ask your journeyman what they recommend for each tool, and take advantage of holiday sales at the big home centers, where tool prices drop significantly.

Two things to avoid: do not buy a pre-packaged apprentice tool set from a discount store, and do not buy the cheapest version of every tool. The pre-packaged sets are padded with tools you will never use and short on the wrenches you will use every day, and the cheapest tools fail at the worst moments. Buy the tools on this list individually, choosing a reputable brand for the wrenches and cutters and mid-range for the rest. Ask your journeyman before buying anything over 50 dollars, because they may have a preference or a spare you can borrow. And remember that your tool collection is a career investment, not a one-time purchase. The twenty tools in this guide will carry you through your first year and well into your second, and by then you will know exactly what to buy next, because your work will have told you. Good luck, and take care of your tools. They will take care of you.
