Is your kitchen mixer tap leaking? A dripping tap not only wastes water but can also hike up your water bills and harm your cabinets. Luckily, fixing it yourself can save you some cash and give you a nice sense of pride. This guide will walk you through finding out why it's leaking and show you how to fix it step-by-step.


Understanding the Problem: Why Is My Kitchen Mixer Tap Leaking?


Before diving into the fix, it’s good to know some usual culprits behind a leaking tap. Here are a few common reasons:


1. Worn Washers: Over time, rubber washers get old and crack.

2. Damaged O-Rings: These seals inside the tap handle can wear out.

3. Broken Washers: Similar to O-rings, broken washers cause leaks, especially when they get damaged.

4. Corroded Valve Seat: This part, where the tap washer rests, can corrode and cause improper sealing.

5. Loose Parts: Loose screws or bolts inside your tap might be the reason for leaks.


Knowing these can help you decide how best to fix your leaky tap.


Tools and Materials Needed to Fix a Leaking Tap


Here’s what you’ll need:

- Adjustable wrench

- Screwdriver (flathead and Phillips)

- Replacement washers or O-rings (right size)

- Plumber's grease

- Towels or a small container for catching water


Step-by-Step Guide to Fixing a Leaky Kitchen Tap


Step 1: Shut Off the Water Supply

Always start by turning off the water supply. This prevents any small floods. You can usually find the water shut-off valves under the sink. Turn them clockwise to close.


Step 2: Let the Tap Dry

After shutting off the water, open the tap and let any remaining water drain out. This avoids splashing while you fix it.


Step 3: Remove the Tap Handle

Take off the handle to access the internal parts. You might need to unscrew a decorative cap first, depending on your tap's design. Use the right screwdriver to undo the screws and lift off the handle carefully.


Step 4: Check the O-Ring and Washer

Pull out the cartridge to access the O-ring and washer. Inspect them closely. If they’re cracked or misshapen, they need replacing.


Step 5: Remove the Cartridge or Valve

In cases where the mixer tap leaks, take out the cartridge. Some taps need you to pull the cartridge out, while others might need you to loosen a retaining nut with a wrench. Make sure you note how everything is assembled before removing parts.


Step 6: Replace the O-Ring or Washer

If you find any worn parts, it's best to replace them. Buy the right size washers from a nearby hardware store. Clean where the washer and O-ring sit, then apply a thin layer of plumber's grease to the new parts to help them seal and make installation easier.


Step 7: Reassemble the Tap

Put the cartridge back in place and secure all nuts without overtightening. Replace the handle and screws, plus any decorative caps.


Step 8: Turn the Water Supply Back On

Once reassembled, turn the water supply back on by rotating the shut-off valves counterclockwise.


Step 9: Test for Leaks

Turn the tap on and off a few times to check for leaks. Look around the area you worked on, especially the handle and base. If it still leaks, revisit the steps and ensure everything is correctly in place.


Fixing a leaky kitchen tap yourself is not only satisfying but also saves money on bills and prevents potential water damage. Following this guide will help you address leaks easily. Regular maintenance can prevent future leaks, but if issues persist, seeking help from a professional plumber might be wise.
