Plumbing tools

A homeowner needs surprisingly few plumbing tools: a good plunger, a basin wrench, adjustable and pipe wrenches, channel locks, PTFE tape, a hand drain auger, and an inexpensive water pressure gauge. Rent or hire out anything past that. Power drain machines, torches, and pipe-threading equipment cause more expensive damage in inexperienced hands than the job would have cost to hire out.

The single most underrated homeowner tool is a water pressure gauge that screws onto a hose bib. It tells you in 30 seconds whether high static pressure is quietly wearing out every valve in the house — a diagnosis a plumber would otherwise charge you an hour to make.

For clogs, a flange plunger and a 25-foot hand auger handle most fixture blockages. Beyond that you're into main-line territory, and a rented power drain machine can punch through a pipe wall, wrap around a cast-iron joint, or shred a section of old clay. That's a rental that turns a routine service call into an excavation.

PEX has made some repairs genuinely DIY-friendly. Push-to-connect fittings and crimp tools let a careful homeowner make sound connections without soldering. That said, connections behind drywall or in inaccessible space are the wrong place to learn — practice on accessible runs first, and pressure test before you close anything up.

Do not solder in a wall cavity or near insulation unless you know what you're doing and have fire watch discipline. Torch work is how DIY plumbing turns into a house fire. If a repair requires sweating copper in a confined space, hire it out.

How to choose

Buy the basin wrench: It's a single-purpose tool and it's the only practical way to reach faucet mounting nuts under a sink. Everyone who has tried without one regrets it.
Own a pressure gauge: Cheap, instant, and it catches a problem that silently shortens the life of everything downstream of it.
Rent, don't buy, the power auger — and think twice: Power drain machines are effective and unforgiving. On old cast iron or clay, the downside risk is a dig, not a repair.
Keep push-to-connect couplings on hand: A couple of the right sizes in a drawer lets you make an emergency repair in minutes while you wait for a plumber, on copper, PEX, or CPVC.
Pressure test before you close a wall: Any repair inside a wall gets tested under pressure and left open for at least a day before drywall goes back. No exceptions.

FAQ

Plumbing tools — common questions

Still have a question? Talk to our team →

Can I snake my own main sewer line?

You can, but it's often a bad trade. Rented power augers can damage old clay or cast-iron pipe, and the resulting repair costs far more than the service call you avoided. For fixture-level clogs, a hand auger is fine.

Is PTFE tape or pipe dope better?

Both work on threaded connections and many plumbers use both together. Tape is easier for occasional users. Neither belongs on compression fittings or flare fittings, which seal on metal-to-metal contact.

What water pressure should my house be at?

Ask your plumber or your local water utility what's appropriate for your area and equipment — acceptable ranges are set by local code and manufacturer specs. Measuring it with a gauge is the first step; interpreting it should be against your own jurisdiction's numbers.

Are push-to-connect fittings reliable?

They're widely used and code-accepted in many jurisdictions, but acceptance varies. Confirm with your local building department before using them in concealed locations.
