How To Repair Leaking Bathroom Mixer Taps

Leaking bathroom mixer taps are a common household problem that can be frustrating and costly. Not only does a leaky tap waste water and increase your water bill, but it can also damage your bathroom fixtures and lead to mold growth. Fortunately, most leaking mixer taps can be repaired with a few simple tools and some basic knowledge. This article will guide you through the steps of repairing a leaking bathroom mixer tap.

Identify the Source of the Leak

The first step in repairing a leaking bathroom mixer tap is to identify the source of the leak. There are typically two main areas where leaks occur: the cartridge or the washer.

Cartridge Leaks: Cartridge leaks often manifest as a constant drip, even when the tap is fully closed. This is because the cartridge, a small internal component that controls water flow, has worn down or become damaged.

Washer Leaks: Washer leaks are often characterized by dripping when the tap is turned on and then off. The washer, a small rubber or plastic seal that sits between the tap handle and the spout, can wear down or become damaged over time.

To determine the type of leak, carefully observe the tap while it is turned on and off. If the leak persists even when the tap is closed, it is likely a cartridge issue. If the leak only occurs when the tap is turned on or off, it is likely a washer issue.

Replacing the Cartridge

If the leak is coming from the cartridge, you will need to replace it. This process typically involves the following steps:

Turn off the water supply.

Locate the shut-off valve for the bathroom sink and turn it off.

Remove the handle and cap.

Most mixer taps have a small screw on the handle. Use a screwdriver to remove this screw. Once the screw is removed, the handle should come off easily. Underneath the handle, you'll find a decorative cap that may also need to be removed.

Remove the cartridge.

The cartridge is usually held in place by a small ring or nut. Use a wrench or adjustable pliers to loosen this ring or nut. Once it is loose, you can pull the cartridge out of the tap body.

Install the new cartridge.

Make sure the new cartridge is compatible with your mixer tap. Insert the new cartridge into the tap body and tighten the ring or nut securely.

Reassemble the tap.

Put the cap back on, followed by the handle, and tighten the screw.

Turn on the water supply and test the tap.

Once the water supply is turned back on, check for any leaks. If everything is working properly, you have successfully replaced the cartridge.

Replacing the Washer

If the leak is coming from the washer, you will need to replace it. Here are the steps involved:

Turn off the water supply.

Locate the shut-off valve for the bathroom sink and turn it off.

Remove the handle and cap.

As in the cartridge replacement, remove the screw from the handle, take off the handle, and remove the cap.

Remove the packing nut.

The packing nut is a threaded ring located underneath the cap. Use a wrench or adjustable pliers to loosen and remove the packing nut.

Remove the old washer.

The washer is a small rubber or plastic disc that sits on top of the valve stem. You may need to use a small screwdriver or pliers to pry it off.

Install the new washer.

Make sure the new washer is compatible with your mixer tap. Place the new washer on top of the valve stem.

Reassemble the tap.

Place the packing nut back on and tighten it securely. Replace the cap and the handle, and then tighten the screw.

Turn on the water supply and test the tap.

Once the water supply is turned back on, check for any leaks. If everything is working properly, you have successfully replaced the washer.
