A leaking tap might seem like a small issue, but those constant drips can waste thousands of litres of water every year — and add extra dollars to your bill. While some leaks are quick fixes, others are a sign of bigger plumbing problems.
In this guide, we’ll explain the main reasons taps leak, how to troubleshoot them, and when it’s time to call in a professional plumber.
1. Why Leaking Taps Matter
- Water waste: A dripping tap can waste up to 20,000 litres annually.
- Higher bills: Those drops add up quickly.
- Hidden damage: Continuous leaks can stain sinks, corrode fittings, or damage cabinetry.
2. Common Causes of a Leaking Tap
- Worn-out washers: The most common culprit. Washers degrade over time and stop sealing properly.
- Damaged O-rings: If the handle itself leaks, it’s usually the O-ring.
- Loose parts: Over time, nuts, screws, and fittings can work loose.
- Corroded valve seat: Minerals and rust can cause leaks around the spout.
- High water pressure: Pressure that’s too high can stress fittings and cause leaks — sometimes linked to broader plumbing issues.
3. DIY Checks and Fixes
If you’re comfortable with basic repairs, you can try:
- Turn off the water at the mains before starting.
- Replace the washer: Unscrew the tap, remove the old washer, and install a new one.
- Tighten fittings: Sometimes all it takes is a careful turn of a wrench.
⚠️ Be cautious: forcing fittings can damage the tap or pipes, turning a small job into a bigger problem.
4. When It’s More Than a Washer
If you’ve changed the washer and the leak continues, it could be:
- A pipe leak behind the wall (time to book leak detection).
- Excess water pressure affecting multiple fixtures.
- Corroded pipes or fittings that need replacement.
5. Why Professional Help Pays Off

- Identify and fix the root cause, not just the symptom.
- Prevent small leaks from turning into major water damage.
