Step-by-Step Guide to Fixing a Mixer Tap that is Leaking Under the Sink
Step 1: Turn Off the Water Supply
The first step is to turn off the water supply to the tap. Locate the isolation valve under the sink and turn it off. If you cannot find the isolation valve, turn off the main water supply to the house.
Step 2: Remove the Tap Handle
Remove the tap handle by unscrewing the screw at the base of the handle. Use a flathead screwdriver or an Allen key, depending on the type of screw. Set the handle aside.

Remove the cartridge by unscrewing the retaining nut that holds it in place. Use an adjustable wrench to turn the nut counterclockwise. Pull the cartridge out of the tap body.
Step 4: Inspect the Cartridge
Inspect the cartridge for any signs of damage or wear. Check the O-rings and the valve seat for any signs of wear or corrosion. If any parts are damaged, replace them with new ones.
Step 5: Replace the Cartridge
Replace the cartridge by inserting it back into the tap body. Make sure it is seated properly and secure it with the retaining nut. Use the adjustable wrench to tighten the nut clockwise.
Step 6: Reassemble the Tap Handle
Reassemble the tap handle by screwing it back onto the cartridge. Use the screwdriver or Allen key to tighten the screw at the base of the handle.
Step 7: Turn On the Water Supply
Turn on the water supply and turn on the tap to test it. Check for any leaks or drips. If there are no leaks, you have successfully fixed the mixer tap.
