You don't need a plumber's van to handle basic plumbing maintenance, but having the right tools — and knowing what each is for — makes the difference between a quick fix and a botched job. Here are 10 useful plumbing tools every homeowner should know about, and clear guidance on what you should and shouldn't attempt yourself.
1. Cup plunger
The standard cup plunger is for sinks and basins — the flat cup seals against a flat surface to create the vacuum needed to dislodge a blockage. For toilets, you need a flange plunger (see below). A cup plunger is the first tool to reach for when a sink or basin drain is slow.
2. Flange plunger (toilet plunger)
A flange plunger has a soft flap that folds out from the cup, designed to fit the curved shape of a toilet trap. If your toilet is blocked, a flange plunger is the right tool — a cup plunger won't seal properly in the toilet bowl.
3. Adjustable spanner (shifter)
An adjustable spanner is essential for loosening and tightening tap bonnets, compression fittings, and isolation valves. A medium-sized shifter covers most household plumbing tasks. Always protect chrome fittings with a cloth to avoid scratching.
4. Pipe wrench
A pipe wrench grips and turns pipes and fittings. It's a heavy tool with toothed jaws that bite into the metal. Pipe wrenches are for galvanised and steel pipe work — they'll mark chrome and brass fittings, so use an adjustable spanner or a strap wrench for those. Most homeowners won't need a pipe wrench often, but it's useful for older pipework.
5. Slip-joint pliers (water pump pliers)
Slip-joint pliers grip a range of sizes and are useful for holding fittings, turning stubborn nuts, and gripping pipes. They're a versatile addition to any toolkit and complement an adjustable spanner.
6. Sink strainer
Not a tool as such, but an essential preventative device. A sink strainer sits in the drain hole and catches food scraps before they enter the pipe. It's the single most effective way to prevent kitchen drain blockages.
7. Drain snake (hand auger)
A hand drain snake is a flexible coil that can be fed into a drain to break up soft blockages close to the fixture. It's more effective than a plunger for stubborn sink blockages but won't clear tree roots or solid objects. If a snake doesn't clear the blockage, it's time to call a plumber — see our blocked drains service
8. Basin wrench
A basin wrench is a long-handled tool with a swivelling jaw, designed for reaching up behind a basin to loosen and tighten the nuts that hold taps in place. It's the one tool that makes tap replacement possible without contortion — without it, changing a tap on a pedestal basin is extremely difficult.
9. Thread seal tape (Teflon tape)
Thread seal tape is wrapped around threaded fittings to create a watertight seal. It's used when assembling or reassembling threaded pipe and fitting connections. Use a few wraps in the direction the nut will tighten, so the tape doesn't unravel as you tighten.
10. Bucket and towel
Underrated but essential. Whenever you open a plumbing fitting, water will come out — usually more than you expect. A bucket and towel under the work area prevent a small spill from becoming a mess.
What to attempt yourself (and what not to)
With these tools, a confident homeowner can handle: clearing simple sink and toilet blockages with a plunger or snake, replacing a tap washer, cleaning an aerator, and replacing a flexible hose. Anything involving gas, concealed pipework, the main sewer line, or the hot water system should be left to a licensed plumber. See our guide on common DIY plumbing mistakes
