How To Fix A Leaking Mixer Tap in 6 Easy Steps

Dealing with a leaking mixer tap can be annoying and wasteful. But fixing it yourself is an easy DIY job that anyone can tackle in about 30 minutes with basic tools and a little know-how.

In this comprehensive guide, we’ll walk through the steps to fix a mixer tap leaking from the base in 6 straightforward steps. Follow along to stop the leak for good and prevent plumbing damage.

Gather the Necessary DIY Tools

Before starting any home repair project, it’s important to gather all the required tools and materials. To fix a leaky mixer tap, you’ll need:

• Adjustable wrench – to loosen nuts and connections
• Phillips screwdriver – to remove the handle screw
• Replacement cartridge or seals (if required)
• Rags or towels – to contain water drips
• Bucket – to catch dripping water
• Flashlight – to see small connections clearly

Having these supplies on hand will allow you to complete the repair efficiently.

Shut Off the Water Supply Lines

The first crucial step is to turn off the water supply to the leaky faucet. This prevents any more water from leaking out as you work.

Under the sink, locate the isolation valves on the hot and cold water lines. Turn them clockwise as far as they will go to fully shut off the water.

Closing these valves stops the flow of water and leakage while you diagnose and fix the dripping mixer tap.

Remove the Handle and Chrome Ring

With the water off, you can disassemble the mixer tap to access the internal components causing the leak.

Start by removing the handle. Use your Phillips screwdriver to loosen the grub screw holding the handle in place.

Gently pry the handle off, taking care not to damage the finish. This exposes the inner ceramic cartridge.

Next, unscrew the decorative chrome dress ring surrounding the cartridge by turning it counterclockwise.

Removing these outer pieces allows you to inspect the cartridges and valves.

Inspect and Replace the Faulty Cartridge

Examine the ceramic cartridge closely for cracks, pitting, or other wear using a flashlight. The cartridge controls the flow and mixing of hot and cold water in the faucet.

If it is corroded or damaged, replace it with an identical new cartridge. Use an adjustable wrench to remove the hex nut holding the old cartridge and install the replacement.

A faulty cartridge is the most common cause of a leaking mixer tap. Replacing it can often fix the leak on its own.

Check and Replace Worn Washers and Seals

While the faucet is disassembled, inspect the condition of all O-rings and seals for cracks or wear. Worn seals allow water to leak out around the cartridge.

Replace any damaged O-rings with new ones of the same size. Also, replace the inlet seals. Apply some plumber’s grease on the new seals to help create a watertight connection.

Reassemble the Mixer Tap

Once any worn parts have been replaced, you can reassemble the repaired mixer tap by reversing the disassembly steps:

• Insert the cartridge and tighten the hex nut
• Replace the chrome dress ring
• Attach the faucet handle with the grub screw
• Ensure all connections are tight

Take care to properly align all components and do not over tighten.

Turn the Water Back On and Test

The moment of truth has arrived! Turn the isolation valves counterclockwise to turn the water supply back on.

Check under and around the tap closely for any remaining drips or leaks once the water is flowing again.

If no more water leaks out, you’ve successfully fixed the drippy mixer tap! Turn the tap on fully and test both hot and cold water flow and mixing.

If any leaks persist, there may be an additional issue needing attention by a professional plumber.
