How to Fix a Leaking Tap at Home: A Step-by-Step Guide

A leaking tap can be annoying and wasteful, but fixing it is often a straightforward DIY task. Here’s a comprehensive guide to help you identify the problem and repair your leaking tap effectively.

Tools and Materials Needed

• Adjustable wrench or pliers
• Screwdriver (flathead and Phillips)
• Replacement washers or O-rings (specific to your tap type)
• Plumber’s grease
• Bucket or towel (to catch drips)

Step-by-Step Instructions

1. Turn Off the Water Supply

Before you begin, locate the water shut-off valves under the sink and turn them off. If there are no individual valves, turn off the main water supply for your home.

2. Drain the Tap

Open the tap to drain any remaining water. This will help you avoid spills and make the repair process easier.

3. Cover the Drain

To prevent small parts from falling into the drain, cover it with a cloth or use a sink strainer.

4. Disassemble the Tap

• Remove the Handle: Use a screwdriver to remove any screws securing the handle. If it’s stuck, you may need to gently pry it off with a flathead screwdriver.
• Take Off the Packing Nut: Use an adjustable wrench or pliers to loosen and remove the packing nut beneath the handle. Be cautious not to damage the tap body.

5. Inspect the Components

Once disassembled, check the following parts:

• Washer or O-ring: Look for signs of wear, such as cracks or deformation. This is often the cause of leaks.
• Valve Seat: Check for corrosion or damage. If it’s rough, it may need to be replaced or resurfaced.

6. Replace Washers or O-rings

• If the washer or O-ring is damaged, remove it and replace it with a new one. Make sure to choose the right size.
• Apply a bit of plumber’s grease to the new washer or O-ring to ensure a better seal.

7. Reassemble the Tap

• Reattach the Valve Seat: If you removed it, reattach it securely.
• Replace the Packing Nut: Hand-tighten the packing nut, then use the wrench to tighten it gently—avoid overtightening.
• Reattach the Handle: Align it correctly and secure it with screws.

8. Turn On the Water Supply

Slowly turn the water supply back on. Open the tap to let any air escape and ensure that everything is functioning correctly.

9. Check for Leaks

Observe the tap for any leaks. If it’s still leaking, you may need to revisit the disassembly and ensure that all parts are properly seated and secured.

Conclusion

Fixing a leaking tap is a manageable task that can save you money and conserve water. By following these steps, you can tackle the repair with confidence. If you’ve tried these fixes and the tap continues to leak, it may be time to consult a professional plumber.
