Plumbing Tools for Homeowners: What You Actually Need

Most plumbing emergencies happen at the worst possible time. Having a basic plumbing toolkit means you can handle common problems yourself - or at least minimise damage while waiting for a plumber.

Here's what actually matters for home plumbing.

The Essentials

Adjustable Wrenches

The most-used plumbing tool. You need at least two sizes - one to hold, one to turn. Our adjustable wrench collection includes quality options from Bahco and Draper.

Sizes to have: 8" (200mm) and 12" (300mm) cover most home plumbing.

Plungers

Yes, the humble plunger. You actually need two types:

• Cup plunger - For sinks and flat drains
• Flange plunger - For toilets (has an extended flap)

Pipe Wrench

For gripping round pipes and fittings. The serrated jaws bite into the metal. Essential for stubborn connections.

PTFE Tape

Wrap this around threaded connections to create a watertight seal. Cheap, easy to use, prevents leaks. Always wrap in the direction of the thread.

Level Two Tools

Basin Wrench

Ever tried to reach the nuts under a sink? A basin wrench has a long handle and pivoting head designed exactly for this job. Makes tap replacements much easier.

Pipe Cutter

Cleaner cuts than a hacksaw, and you can use it in tight spaces. For copper pipes, a proper pipe cutter is worth having.

Plumber's Snake / Drain Auger

When the plunger fails, a drain snake can clear deeper blockages. A manual one handles most household clogs.

Compression Fitting Kit

Allows you to join pipes without soldering. Useful for emergency repairs or if you're not confident with a blowtorch.

Detection and Prevention

Leak Detector

A small investment that can save thousands. Battery-powered units alert you to water where it shouldn't be - under sinks, near washing machines, in basements.

Stopcock Key

Your main stopcock might be underground with a recessed fitting. A proper key lets you shut off water to the whole house in emergencies.

Know Your Stopcocks

Before any emergency, find and test:

• Main stopcock - Usually under the kitchen sink or in a utility area
• Outside stopcock - Near the property boundary
• Isolation valves - Under individual taps and toilets

Turn them occasionally to make sure they work. Stopcocks that haven't moved in years tend to seize.

When to Call a Professional

Some jobs need a qualified plumber:

• Gas work (legally requires Gas Safe registration)
• Major alterations to supply pipes
• Boiler issues
• Anything you're not confident about

Knowing your limits isn't weakness - it's wisdom. A small leak you can't fix is better than a flood you caused.

Building Your Kit

Start with the essentials and add as needed. Most home plumbing issues can be handled with adjustable wrenches, plungers, and PTFE tape. Everything else is useful but not urgent.
