How Do I Change a Washer on a Bathroom Mixer Tap?

A leaking bathroom mixer tap can be a source of frustration and wasted water. Often, the culprit is a worn-out washer, a small rubber or plastic disc that seals the water flow when the tap is closed. Replacing a washer is a relatively simple DIY task that can save you money and time. This article will guide you through the process of changing a washer on a bathroom mixer tap, providing clear instructions and helpful tips.

Tools and Materials

Before you begin, ensure you have the following tools and materials readily available:

A screwdriver (usually a Phillips head)
Adjustable wrench or pipe wrench
Basin wrench (optional, but recommended for hard-to-reach taps)
Replacement washer (check the size and material required for your tap)
Teflon tape (optional, for sealing threads)
Rag or towel for cleaning
Bucket or bowl for catching water

Steps for Changing a Bathroom Mixer Tap Washer

Follow these steps to replace the washer on your bathroom mixer tap:

Turn off the water supply. Locate the shut-off valve for your bathroom and turn it fully clockwise to stop the water flow.
Drain the tap. Open the faucet to release any remaining water inside the tap.
Remove the tap handle. Look for a screw or cap underneath or behind the handle. Use a screwdriver to remove it. Once the screw is removed, you should be able to pull the handle off the tap.
Remove the tap cartridge or stem. This is the part that holds the washer. It may be held in place by a nut or a threaded stem. Use an adjustable wrench or pipe wrench to loosen and remove the nut or stem. If you are working with a cartridge, you may need to gently wiggle it to release it from its housing.
Remove the old washer. The washer is typically found at the bottom of the cartridge or stem. Carefully pry it off using a small screwdriver or pliers.
Install the new washer. Position the new washer on the bottom of the cartridge or stem, ensuring it is properly seated.
Reassemble the tap. Reinstall the tap cartridge or stem, making sure it is securely in place. Replace the nut or threaded stem, tightening it by hand first and then using a wrench to tighten it fully. Reinstall the tap handle and screw it back in place.
Turn the water supply back on. Slowly turn the valve counter-clockwise to restore water flow. Check for leaks around the tap and tighten any loose fittings as needed.

Tips for Success

Here are some additional tips to ensure a successful washer replacement:

Identify your tap type. There are different types of mixer taps, including cartridge taps and ceramic disc taps. Cartridge taps typically use a washer, while ceramic disc taps have a ceramic disc that seals the water flow. Make sure you purchase the correct replacement parts for your tap type.
Use Teflon tape. Applying Teflon tape to the threads of the tap cartridge or stem can help to prevent leaks. Wrap the Teflon tape around the threads in a clockwise direction, overlapping each layer by half.
Check for other leaks. If your tap is still leaking after replacing the washer, there may be other issues, such as a worn-out O-ring or a damaged valve. Inspect the tap for other potential problems.
Consider a professional plumber. If you are unsure about the process or have a complex tap, it is always best to consult a professional plumber. They have the experience and expertise to diagnose and fix any plumbing issues.

Replacing a washer on a bathroom mixer tap is a straightforward task that can be achieved with a few simple tools and some patience.
