A Beginner’s Guide to Fixing a Leaky Kitchen Tap

A leaky Kitchen tap is not just an annoying drip—it can waste water, increase your bills, and even cause damage over time. Fortunately, fixing a leaky tap is easier than you might think! In this guide, we’ll walk you through the simple steps to identify and fix the problem, saving you time and money.

Why Is My  Kitchen Tap Leaking?

Before you start, it’s important to understand why your tap is leaking. The most common causes include:

• Worn-out washers (rubber at the end of your valve)  – The rubber washer inside your tap can degrade over time.
• Damaged ceramic discs  – ceramic disc in a quarter turn valve. This can get damaged over time if your water has small debris e.g limescale.
• Damaged O-rings – These small rubber rings help create a tight seal but can wear out.
• Loose or corroded parts – Mineral buildup or general wear and tear can cause leaks.
• Faulty tap cartridge – If your tap uses a ceramic disc or cartridge system, it may need replacing.

Tools You’ll Need

• Adjustable spanner (wrench)
• Screwdriver
• Replacement washer, O-ring, or cartridge (depending on your tap type)
• Plumber’s tape
• Cloth or towel to catch any water spills

Step-by-Step Guide to Fixing a Leaky Tap

Step 1: Turn Off the Water Supply

Before you begin, turn off the water supply at the mains or the isolation valve under the sink. This prevents any unexpected water flow while you’re working.

Step 2: Remove the Tap Handle

Depending on the type of tap you have, you may need to remove a decorative cap or screw to access the internal components. Use a screwdriver to gently lift off the handle.

Step 3: Dismantle the Tap and Identify the Issue

• If you have a traditional compression tap, check the washer and O-ring. Replace them if they appear worn or damaged.
• If you have a ceramic disc tap, the entire cartridge may need replacing.
• Inspect for any corrosion or mineral buildup and clean if necessary.

Step 4: Replace the Faulty Component

Once you’ve identified the problem, replace the necessary part with a genuine spare for a perfect fit. Using genuine tap spare parts ensures durability and optimal performance.

Step 5: Reassemble and Test

Carefully put the tap back together, ensuring all parts are secure. Turn the water supply back on and test your tap. If the leak has stopped, congratulations—you’ve successfully fixed your tap!

When to Call a Professional

If your tap continues to leak after replacing the washer, O-ring, or cartridge, the issue might be more complex, such as internal pipe damage. In this case, it’s best to consult a professional plumber.
