Why Taps Leak and How You’ll Stop It

A leaking tap may seem like a small annoyance, but over time it can waste litres of water, increase your bills, and even cause damage to your fixtures or surfaces. Whether it’s a slow drip or a steady trickle, knowing why taps leak and how to stop it can save you stress, time, and money.

Let’s break down the most common causes of leaking taps and what you can do to fix the issue quickly and effectively.

Common Reasons Taps Start Leaking

Leaking taps are usually the result of worn-out internal components or improper installation. Here are some of the most frequent causes:

1. Worn or Damaged Washer

One of the biggest culprits behind a leaking tap is a worn rubber or ceramic washer. Over time, washers lose shape due to pressure, friction and water flow. When this happens, the washer can no longer form a tight seal, leading to dripping.

2. Loose or Faulty O-Ring

Mixer taps often use O-rings to control flow and seal internal parts. If the O-ring loosens or deteriorates, water may leak from the base or handle.

3. High Water Pressure

If your water pressure is too high, it can force water through seals and washers that aren’t designed to handle such force. This can lead to sudden or intermittent leaks.

4. Corrosion or Build-Up Inside the Tap

Hard water, sediment and corrosion may wear down internal components, including cartridges and valve seats. Over time, this creates gaps that allow water to escape.

How to Fix a Leaking Tap

Before grabbing your tools, make sure you shut off the water supply from the valve or mains.

Here’s a simple step-by-step approach most homeowners can safely attempt:

Step 1: Identify the Type of Tap

• Compression tap
• Mixer tap
• Ball-type faucet
• Ceramic disc or cartridge tap

Knowing the type helps determine whether the washer, O-ring, or cartridge needs replacing.

Step 2: Remove the Handle

Unscrew the tap handle using a screwdriver or Allen key. Keep track of screws and small parts so nothing goes missing.

Step 3: Replace the Washer, Cartridge or O-Ring

• If it’s a washer-based tap, swap out the old washer for a new one.
• For ceramic or mixer models, replacing the cartridge or O-ring may fix the issue.

Step 4: Reassemble and Test

Put the handle back, tighten any screws, and restore the water supply to test your repair.
