How to Fix a Leaking Bathroom Mixer Tap

A leaking bathroom mixer tap can be a frustrating problem, but it's usually not too difficult to fix yourself. With the right tools and a little bit of know-how, you can save yourself the cost of calling a plumber. ### Tools and Materials You'll Need Before you start, gather the following tools and materials: * Adjustable wrench or spanner * Allen wrench or hex key * Flat-head screwdriver * Phillips-head screwdriver * Replacement washer or O-ring * Plumber's grease ### Step-by-Step Instructions

1. Shut Off the Water Supply

The first step is to turn off the water supply to the tap. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to close them.

2. Open the Faucet

Next, open the faucet to release any remaining water pressure. Leave the faucet open until all the water has drained out.

3. Remove the Aerator

The aerator is the small, mesh screen at the tip of the faucet. It helps to mix air with water to create a more forceful stream. To remove the aerator, unscrew it counterclockwise with your fingers or a wrench.

4. Remove the Handle

Once the aerator is removed, you should see a screw in the center of the handle. Use an Allen wrench or hex key to loosen the screw and remove the handle.

5. Remove the Cartridge

Behind the handle, you'll see the cartridge. This is the part that controls the flow of water. To remove the cartridge, use an adjustable wrench or spanner to loosen the nut that holds it in place. Once the nut is loose, pull the cartridge straight out.

6. Inspect the Washer or O-Ring

The washer or O-ring is a small, rubber seal that sits inside the cartridge. If the washer or O-ring is worn or damaged, it can cause the tap to leak. Inspect the washer or O-ring and replace it if necessary.

7. Apply Plumber's Grease

Before reassembling the tap, apply a thin layer of plumber's grease to the washer or O-ring and to the threads of the cartridge. This will help to prevent leaks and make it easier to install the cartridge.

8. Reassemble the Tap

To reassemble the tap, follow the steps in reverse order: * Insert the cartridge into the body of the tap. * Tighten the nut that holds the cartridge in place. * Replace the handle. * Tighten the screw that holds the handle in place. * Replace the aerator.
