Materials and Tools Needed for Replacing a Washer

To successfully replace a washer in a leaking tap, you will need the following materials and tools:

Replacement washer

First and foremost, you will need a replacement washer for your tap. It’s important to find the right size and type of washer to ensure a proper fit.

Adjustable spanner

An adjustable spanner, also known as a wrench, will be useful for loosening and tightening various components of the tap.


A screwdriver is needed to remove screws or caps that may be holding the tap handle in place.

Pipe wrench

In some cases, a pipe wrench may be necessary to remove stubborn or rusted components of the tap.

Plumber’s tape

Plumber’s tape, also known as PTFE tape or thread seal tape, is used to create a watertight seal when reassembling the tap.

Rags or towels

Having rags or towels on hand is always helpful to clean up any spills or drips during the replacement process.

Bucket or container

It’s a good idea to have a bucket or container nearby to catch any water that may come out when disconnecting the tap.

Preparation and Safety Measures

Before you begin replacing the washer in your leaking tap, there are a few important preparation and safety measures to keep in mind:

Turn off the water supply

To avoid any potential water damage or accidents, always remember to turn off the water supply before starting the replacement process. Locate the shut-off valve near your tap and turn it clockwise until it is fully closed.

Prepare the work area

Clear the area around your tap and make sure you have enough space to work comfortably. Remove any objects or obstacles that may get in the way during the replacement process.

Protective gear

Although replacing a washer in a tap is generally a safe task, it’s always a good idea to wear protective gear. Consider wearing gloves and safety glasses to protect your hands and eyes during the process.

Gather necessary tools and materials

Before you begin, gather all the necessary tools and materials mentioned earlier. Having everything at hand will make the replacement process smoother and more efficient.

Removing the Tap Handle

Now that you are prepared and have all the necessary tools and materials, it’s time to remove the tap handle:

Locate the screw or cap

Look for a screw or cap on the top or side of the tap handle. This screw or cap is typically used to secure the handle in place.

Remove the screw or cap

Using a screwdriver, carefully remove the screw or gently pry off the cap. Be sure to keep the screw or cap in a safe place to avoid misplacing it.

Detach the tap handle

Once the screw or cap is removed, you should be able to detach the tap handle from the main body of the tap. Check for any additional screws or clips that may be holding it in place, and remove them if necessary.

Accessing the Valve and Washer

With the tap handle removed, you can now access the valve and the washer that needs to be replaced:

Identify the tap valve type

Before proceeding, it’s important to identify the type of tap valve you have. Common types include compression valves, ceramic disc valves, and cartridge valves. This information will be useful when selecting the appropriate replacement washer.

Remove decorative coverings

In some cases, you may need to remove decorative coverings, such as a handle cap or trim plate, to fully access the valve and washer. Use a screwdriver or other appropriate tool to remove these coverings if necessary.

Unscrew the valve retaining nut

Locate the valve retaining nut, which is usually situated directly beneath the tap handle. Using an adjustable spanner, carefully unscrew the nut in a counterclockwise direction.

Lift the valve assembly out

Once the retaining nut is removed, lift the valve assembly out of the tap body. Take note of the position of any additional components, such as spacers or o-rings, as you will need to reinstall them correctly.

Replacing the Washer

Now that you have successfully accessed the valve and removed it from the tap body, it’s time to replace the washer:

Inspect the old washer

Take a moment to inspect the old washer. Look for signs of wear, cracks, or other damage that could be causing the leak.

Select the appropriate replacement washer

Using the information gathered earlier about the type of tap valve you have, select the appropriate replacement washer. Pay attention to the size, shape, and material of the washer to ensure a proper fit.

Install the new washer

Carefully place the new washer onto the valve assembly, ensuring that it is properly aligned. Make sure the washer sits flat and snug against the valve.

Reassemble the tap

Reassemble the tap by following the previous steps in reverse. Place the valve assembly back into the tap body and screw the retaining nut back on in a clockwise direction. Reattach any decorative coverings, and securely fasten the tap handle back onto the valve assembly.

Testing for Leaks

After replacing the washer and reassembling the tap, it’s important to test for any remaining leaks:

Reconnect the tap handle

Ensure that the tap handle is securely connected to the valve assembly. Tighten any screws or clips that may be necessary.

Turn on the water supply

Slowly turn on the water supply by turning the shut-off valve counterclockwise. Observe the tap closely for any signs of leaks.

Check for leaks

Inspect the area around the tap, including the base and any connecting pipes or fittings, for any signs of leaks. If you notice any leaks, immediately turn off the water supply and make the necessary adjustments.

Make necessary adjustments

If you find any leaks, try tightening any loose fittings or connections. If the leak persists, you may need to repeat the process and check for any possible errors during the replacement or reassembly.

If the tap still leaks

If your tap continues to leak even after replacing the washer, there may be underlying issues that require further attention. Consider seeking professional assistance to diagnose and fix the problem.

If the tap handle is stuck

In some cases, the tap handle may become stuck or difficult to turn after reassembly. This can be caused by a variety of factors, such as improper reassembly or a damaged valve. Try disassembling and reassembling the tap again, ensuring that all components are properly aligned. If the problem persists, consult a professional plumber for assistance.

If the valve is damaged

While replacing the washer, you may discover that the valve itself is damaged or faulty. In such cases, replacing the entire tap or valve assembly may be necessary. Consult a professional plumber to determine the best course of action.

Maintenance Tips to Prevent Leaking Taps

To prevent future leaks and extend the lifespan of your taps, consider implementing the following maintenance tips:

Regularly inspect and clean tap washers

Periodically inspect your tap washers for signs of wear, damage, or buildup. Clean them if necessary and replace them as soon as you notice any issues.

Avoid overtightening the tap handle

When turning off your taps, avoid overtightening the tap handle. Applying excessive force can cause unnecessary wear and tear on the washer and other components, leading to leaks.

Use plumber’s tape for secure fittings

When reassembling your tap, use plumber’s tape to create a secure seal on threaded fittings. This will help prevent leaks and ensure a watertight connection.

Address leaks promptly

If you notice any leaks, no matter how minor, address them promptly. Ignoring leaks can lead to further damage and potentially more costly repairs down the line.

When to Seek Professional Assistance

While replacing a washer in a leaking tap is a task that many individuals can tackle on their own, there are certain circumstances when it may be best to seek professional assistance:

Complex tap designs

If your tap has a complex design or unique components, it may require specialized knowledge and tools to properly replace the washer. In such cases, a professional plumber will have the expertise to handle the job effectively and efficiently.

Persistent leaks despite replacement

If you have replaced the washer and followed all the necessary steps, but the tap continues to leak, there may be underlying issues that require professional attention. A plumber can assess the situation and determine the best course of action.

Lack of confidence or experience

If you lack confidence or experience in DIY plumbing tasks, it’s perfectly understandable to seek professional help. A plumber can ensure the job is done correctly and provide peace of mind knowing that your tap will be in good hands.


Fixing a leaking tap by replacing the washer is a task that can be easily done with the right materials, tools, and knowledge. By following the step-by-step guide outlined in this article and taking the necessary safety precautions, you can successfully resolve the issue on your own. However, it’s important to recognize when it’s best to seek professional assistance, especially in complex situations or if you lack confidence or experience. By addressing leaks promptly and implementing regular maintenance, you can prevent future leaking taps and potentially save yourself from more extensive repairs.
