A leaking pipe isn’t just inconvenient—it can lead to major water damage, high bills, and structural issues if left unchecked. Whether it’s a slow drip or a sudden burst, acting quickly can save you time, money, and stress. In this guide, we’ll walk you through how to fix a leaking pipe, from emergency containment to permanent repair, including when to call a plumber.

Pipes can leak for several reasons, including:

• Loose joints or fittings
• Corroded pipes (especially older copper pipes)
• Cracked plastic or copper pipework
• Freezing temperatures causing expansion and bursts
• High water pressure stressing pipework

Identifying the source and cause is key to a long-term fix.

1. Turn Off the Water Supply: Locate the stopcock (typically under the kitchen sink or in the utility room) and turn it clockwise. If near electrical outlets, shut off power at the fuse box.
2. Drain the Pipes: Open nearby taps to drain remaining water and relieve pressure.
3. Identify the Leak: Dry the area and inspect for leaks at pipe joints, cracked sections, pinholes, or compression fittings.
4. Apply a Temporary Fix:
   • Pipe Repair Tape: Wrap waterproof plumbing tape tightly around the leak.
   • Epoxy Putty: Apply epoxy putty to seal small cracks or pinholes, letting it cure.
   • Pipe Repair Clamp: Use a clamp for burst sections to seal and resist pressure.
5. Perform a Permanent Repair:
   • Copper Pipes: Cut out the section with a pipe cutter, clean ends, and fit a compression coupling or type with PTFE tape.
   • Plastic Pipes: Cut out the leaking section, use push-fit couplings or feet.
   • Flexible Pipes: Replace the entire hose with a new one of matching size.
6. Test and Inspect: Turn water back on slowly, check for leaks with a tissue, and monitor for moisture over an hour.

When to Call a Plumber: If leaks involve concealed pipework, boiler/heating systems, or major flooding, call a qualified emergency plumber.

Preventing Future Leaks:

• Insulate exposed pipes during colder months
• Keep water pressure within safe levels
• Inspect older pipework every few years
• Avoid hanging heavy items near pipe joints
• Use water leak detectors in vulnerable areas
