How to Fix a Leaking Mixer Tap: A Complete Guide

Electricity bills on the rise? If you’re dealing with a leaking mixer tap, you’re not alone. The frustration of watching your money drip away with every drop of water is all too real. 

But don’t worry, help is at hand. You don’t need to call the leak detection service yet.

In this post, we’ll explore some simple steps on how to fix a dripping mixer tap. So, let’s roll up our sleeves and get your tap back in shape!

What Should You Prepare Before Fixing a Leaking Mixer Tap?

Before you grab your tools, please keep in mind that there are various types of taps, including pillar taps, mixer taps, monobloc taps, and disc taps.

Each type has its own unique design, and understanding these differences is key to fixing mixer tap leaking.

A mixer tap is a common fixture in many homes, easily recognized by its single spout that allows both hot and cold water to flow through. It typically has two handles or levers to control the water temperature.

Unlike a traditional tap with separate spouts, a mixer tap combines the water streams within the spout, making it more convenient for everyday use.

Now, before you dive into repairs, you’ll need to gather some essential tools:

• An adjustable spanner
• A screwdriver (both flathead and Phillips)
• A cloth or sponge for cleaning up any mess

It’s also crucial to familiarise yourself with the different parts of the tap. The inner workings can vary depending on the tap type, which means the solution might differ too. 

Knowing whether you’re dealing with a ceramic disc, washer, or cartridge inside the mixer tap will help ensure you choose the correct repair method.

How to Fix a Leaking Sink Tap?

When it comes to fixing a leaking tap, especially a mixer tap, a little bit of know-how can save you from an ongoing drip that drives up your bills. 

If you’ve noticed your tap leaking from the base, it’s often a sign that the cartridge inside has worn out over time. But don’t worry—fixing it is easier than you might think.

1. Turn off Your Water Supply

Before you start any repairs, you need to turn off the water supply to prevent any flooding mishaps. Locate the valves under your sink and turn them off.

This step is crucial, especially if your mixer tap is leaking from the swivel base, as it ensures you won’t have water gushing out when you remove the tap components.

2. Remove the Lever Handle

Next, grab a screwdriver and remove the lever handle. You’ll typically find a small screw at the base or hidden under a decorative cap.

Carefully unscrew it, and gently lift the handle off. This will give you access to the cartridge inside the tap.

3. Replace the Old Cartridge

Now, it’s time to replace the old cartridge. Take a look inside the tap, and you’ll see the cartridge secured in place with a nut. Use a wrench to unscrew the nut, then remove the cartridge. 

This is the key to stopping that leaking kitchen tap! Take the old cartridge with you to a hardware store to ensure you get the correct replacement.

Once you’ve got the new cartridge, pop it into place, and tighten the nut securely.

4. Refit the Lever Handle

With the new cartridge in place, you can now refit the lever handle. Carefully align it with the cartridge and secure it with the screw you removed earlier.

Make sure everything is tightened up properly to prevent any future leaks (especially at the handle).

5. Test the Water

Finally, turn your water supply back on and test the tap. Turn on the handles and check for any leaks. If everything’s gone to plan, your mixer tap should now be working perfectly, with no more drips or leaks in sight!

And that’s it! You’ve just successfully fixed a leaking tap. But, if the issue is persistent, the problem might be deeper than a worn-out cartridge. That’s why you need leak detection service sometimes.  

FAQ about Leaking Mixer Tap

1. How do you change a washer on a mixer tap?

Remove the tap handle by unscrewing the small screw usually hidden under a cap. Once the handle is off, unscrew the valve to access the washer inside. 

Replace the old washer with a new one of the same size. Finally, reassemble the tap by screwing the valve and handle back in place, then turn the water supply back on.

2. How to replace the O-Ring on a mixer tap?

You’ll usually need to unscrew a small screw or nut to free the spout. Once removed, you’ll see the O-Ring at the base of the spout. 

Slide the old O-Ring off and replace it with a new one, ensuring it sits properly. Reassemble the spout and handle, then turn the water supply back on to check for any leaks.

3. What are the common causes of a leaking tap?

A leaking mixer tap is often caused by a worn-out cartridge, a damaged washer, or a faulty O-Ring. Over time, these components wear out and cause water to leak from the spout or base of the tap. 

4. Do I need a plumber for a leaking tap?

You don’t always need a plumber for a leaking tap. Many leaks are easy to fix with basic tools and a bit of guidance. If the problem is simple, like replacing a washer or cartridge, you can usually handle it yourself. 

However, if you’re unsure or the leak persists after trying to fix it, it’s best to call a plumber to avoid further damage.
