Plumbing Tool Kit: 9 Tools to Own Before Your First Repair
UHBy UsefulHow Editorial Team·Published Jul 14, 2026·Updated Jul 14, 2026·6 min read
Quick AnswerNine tools cover almost every plumbing job a homeowner actually faces: tongue-and-groove pliers, an adjustable wrench, a basin wrench, a pipe wrench, plungers, a hand auger, a tubing cutter, a junior hacksaw, and the tape-and-putty basics. Bought one job at a time, the whole kit runs roughly $150.

Leaks don't check the calendar. The supply line lets go on a Sunday, the toilet starts running at midnight, and the plumber's emergency rate starts at "trip fee" before anyone picks up a wrench. Owning the essential plumbing tools won't make you a plumber, but it turns most of those calls into a 30-minute fix. One habit matters more than any tool on this list, though: before you loosen a single fitting, know how to shut off the water to your house. Every repair below assumes the water is off and the line is drained.
Grip and Turn: The Wrenches
The first three
- Tongue-and-groove pliers (10-inch) — the single most-used plumbing tool in most houses. The adjustable jaw grabs trap nuts under sinks, holds a faucet body still while you work, and pulls the odd nail. If you buy one tool today, buy this one.
- Adjustable wrench (10-inch) — for supply-line nuts, shutoff valves, and anything with flat sides. Spend a little more for a jaw that doesn't wobble; a sloppy jaw rounds off soft brass fittings, and a rounded fitting turns a small job into a big one.
- Pipe wrench (14-inch) — the toothed one. Those teeth bite into round, threaded steel pipe and old iron fittings that nothing else will budge. Keep it off chrome and finished nuts — it leaves marks that don't come out.
With those three you can swap a faucet, rebuild the trap under a sink, and handle the flapper-and-fill-valve work inside a toilet tank, which is most of what goes wrong with one — our guide to fixing a running toilet uses nothing fancier.
Reach the Jobs You Can't See
The awkward-access three
- Basin wrench — a strange-looking tool with a long shaft and a swiveling jaw, built for exactly one job: the faucet mounting nuts hiding up behind the sink basin, where no regular wrench fits. You'll use it twice a decade and be grateful both times.
- Plungers — two of them. The red cup plunger is for sinks and tubs. A toilet needs a flange plunger, the kind with a fold-out rubber neck that seals the bowl outlet. A cup plunger on a toilet mostly just splashes.
- Hand auger (25-foot) — a flexible drain snake you crank by hand. It clears the hair-and-gunk blockages in sink and tub drains that a plunger can't move, and it costs less than one visit from a drain service.
Cut and Seal
The last three, plus consumables
- Tubing cutter — a small wheel tool that scores and snaps copper and plastic supply tubing in clean, square cuts. A saw leaves burrs and angled ends that leak; this doesn't.
- Junior hacksaw — for PVC pipe, rusted bolts, and the one screw that refuses to turn. Compact enough to work inside a vanity cabinet.
- The sealant shelf — PTFE thread tape, plumber's putty, and a small tub of thread-sealant paste. Tape and paste seal threaded joints (one or the other, not neither); putty beds drain flanges and faucet bases. All three together cost less than lunch.
Not tools, but store them with the kit anyway: a five-gallon bucket and a stack of old towels. Plumbing work makes water go places, every single time.
Build It Job by JobDon't buy a 200-piece "plumber's kit" in a plastic case. Half of it is filler you'll never touch, and the pieces you do need are the cheap versions. Buy the tool when the job appears, buy a decent one, and in two years you'll own a kit fitted to your actual house.
AD · In-Article #2 · Mid-Content
Teflon tape everywhere. PTFE tape seals tapered pipe threads only. Wrapped on compression fittings or flare connections it does nothing — worse, it can keep the fitting from seating and cause the leak you were trying to prevent.
Pipe wrench on pretty fittings. The teeth are designed to dig in. On a chrome trap or a new faucet nut, they'll dig in permanently. Adjustable wrench or pliers with a rag over the jaws instead.
One plunger for everything. Covered above, but it's the most common kit mistake in the book. Two plungers, two different shapes, two different jobs.
What This Kit Doesn't Cover
Some jobs stay with the pros no matter what's in your toolbox: anything involving gas lines, a main sewer backup, soldering near framing you can't afford to scorch, and replacing a water heater. Knowing where your kit ends is part of owning it. For the calls you do hand off, it helps to know how much a plumber costs before the quote lands, so you can tell a fair price from a padded one.
Bottom line: Start with the pliers and the flange plunger, add the rest as jobs demand them, and you'll spend about $150 over a couple of years to retire most of the plumbing calls a house generates. Pair the kit with a schedule — the plumbing maintenance checklist for homeowners spreads the valve, hose, and water-heater checks across the year so fewer of those calls happen at all.
Frequently Asked Questions
What is the first plumbing tool a homeowner should buy?Tongue-and-groove pliers, no contest. They grip trap nuts, hold fittings, and improvise a dozen other jobs. Pair them with a flange plunger and you've covered the two most common plumbing emergencies in a house.
Do I need both a pipe wrench and an adjustable wrench?Yes — they do different work. A pipe wrench's teeth bite round pipe and turn it; an adjustable wrench has smooth jaws for nuts and fittings you don't want scarred. Using either one for the other's job either slips or damages the fitting.
Can I use the same plunger on a sink and a toilet?Not well. A flat cup plunger seals against flat surfaces — sinks, tubs, showers. A toilet bowl outlet is curved, and it needs a flange plunger whose neck folds down into the opening to make the seal. Using the sink plunger on a toilet mostly moves water around.
How much should a basic plumbing tool kit cost?Roughly $100–$150 for serviceable versions of the nine tools here, bought individually. Professional-grade versions of the same tools might double that, but for a few jobs a year the mid-range is the right spend.
