How to Fix a Leaking Tap: Step-by-Step Guide (DIY) — Pinnacle Plumbing Solutions

A leaking tap may seem like a small issue, but over time it wastes water, increases your monthly bill, and can even cause moisture damage around sinks and countertops. The good news? Many leaking taps are easy to fix with basic tools and a bit of guidance.

As Pinnacle Plumbing Solutions, proudly serving Umhlanga, Ballito, Phoenix, Queensburgh, Westville, La Mercy, Zimbali and Chatsworth, we’ve put together the most comprehensive DIY guide to help you repair a leaking tap safely and effectively — and know when it’s time to call a professional.

Why Is My Tap Leaking?

Before you begin, it helps to understand why taps leak. Common causes include:

• Worn-out washers or cartridges
• Damaged O-rings
• Loose tap components
• Corrosion inside the tap
• High water pressure
• Incorrect installation

Understanding the root cause will help you fix it faster — and prevent it from happening again.

Tools & Materials You’ll Need

You don’t need professional tools — just a few basic items:

• Adjustable spanner
• Screwdriver
• Replacement washer or cartridge
• O-ring (optional)
• Plumber’s grease
• Cloth or old towel

Step-by-Step Guide: How to Fix a Leaking Tap

1. Turn Off the Water Supply

Before doing anything, switch off the water.

• Look for the isolation valve under your sink and turn it clockwise.
• If there’s no valve, turn off your main water supply.

Tip: Open the tap fully to release pressure.

2. Plug the Drain

Small screws and washers easily fall down the drain.
Use a sink plug or cloth to block the opening.

3. Remove the Tap Handle

Most tap handles have a small decorative cap covering the screw.

1. Pry it open gently with a flathead screwdriver.
2. Unscrew the handle.
3. Lift it upwards to remove it completely.

If your tap has a lever-style handle, check for a small grub screw underneath.

4. Unscrew the Tap Bonnet or Cover

You’ll now see a metal cover (bonnet).
Use a wrench to loosen and remove it — gently to avoid scratches.

5. Check the Washer or Cartridge

Depending on your tap type:

Compression Taps

These have a washer at the bottom.
Remove the spindle and inspect the rubber washer.

If it’s cracked, flattened or brittle → replace it.

Mixer / Modern Single-Lever Taps

These use cartridges instead of washers.
If your tap drips even when the handle is closed tightly, the cartridge is likely worn.

Replace with the same model.

6. Replace the Washer / Cartridge

• Apply plumber’s grease to the new washer or O-ring.
• Insert it into place.
• Tighten components firmly, but not excessively.

7. Reassemble the Tap

• Put the bonnet back.
• Screw the handle on.
• Replace decorative caps.

8. Turn the Water Back On

Slowly reopen the isolation valve.
Test your tap — the leak should now be gone.

When You Should Call a Professional Plumber

If you’re unsure, or your tap continues leaking after replacing washers, the problem might be deeper:

• Internal corrosion
• Incorrect tap installation
• Faulty valve seat
• Damaged pipes
• Extremely high water pressure
