How to Fit a New Bathroom Sink Tap Washer

A leaky bathroom sink tap can be a frustrating and wasteful problem. Fortunately, replacing the washer is often a simple and inexpensive solution. This article will guide you through the process of fitting a new bathroom sink tap washer, equipping you with the necessary knowledge to tackle this common plumbing task.

Tools and Materials

Before embarking on this DIY endeavor, ensure you have the following tools and materials:

New tap washer: Make sure the new washer is compatible with your tap. You can typically find them at hardware stores, plumbing suppliers, or online.
Adjustable wrench: This will be used to loosen and tighten nuts and fittings.
Basin wrench: This specialized tool allows you to access and tighten nuts located in hard-to-reach areas, often found behind sink faucets.
Screwdriver: A screwdriver may be required to remove access panels or decorative caps to access the tap mechanism.
Pliers: Used for gripping and holding small parts.
Rag or cloth: To clean the tap and catch any drips.
Bucket or bowl: To collect water that may drain from the tap during the process.
Optional: Teflon tape or pipe thread sealant, for applying to threads to prevent leaks.

Steps for Replacing a Bathroom Sink Tap Washer

Once you have your tools and materials ready, follow these steps to replace the bathroom sink tap washer:

Turn off the water supply: Locate the shut-off valve for the bathroom sink and turn it off completely. This is usually found under the sink or on the wall behind it.
Drain the tap: Turn on the tap briefly to drain any remaining water in the pipes. This will minimize the amount of water you have to deal with during the replacement process.
Remove the tap handle: Carefully remove the tap handle. This is usually done by unscrewing a decorative cap or using a screwdriver to remove a retaining screw.
Remove the tap stem: Once the handle is removed, you will see the tap stem. Unscrew the stem using the adjustable wrench. Be cautious not to apply excessive force, as this could damage the stem.
Inspect the old washer: The old washer will be attached to the end of the tap stem. Inspect it for wear, tears, or cracks. If the washer is damaged, replace it. It's a good idea to replace the washer even if it looks fine, as it may have become hardened and less effective over time.
Install the new washer: Carefully remove the old washer and replace it with the new washer. Ensure the new washer is properly seated on the stem.
Reassemble the tap: Reattach the tap stem to the tap body, ensuring it is tightened securely. Replace the tap handle and tighten it securely.
Turn on the water supply: Slowly turn the water supply back on and check for leaks. If any leaks are present, re-tighten the connections or check the washer installation for any errors.

Additional Tips

Here are some additional tips for replacing a bathroom sink tap washer. These tips will help you avoid common pitfalls and ensure a successful repair:

Be careful not to over-tighten nuts and fittings: This can damage the tap or cause leaks. Tighten them just enough to create a secure seal.
Inspect other components of the tap: While you have the tap disassembled, take the opportunity to inspect the other components, such as the O-rings and the valve seat. If any of these components show signs of wear or damage, replace them as well.
Use Teflon tape or pipe thread sealant: These products can help prevent leaks by sealing the threads on the tap stem and fittings. Apply a thin layer of Teflon tape or pipe thread sealant to the threads before re-assembling the tap.
If you are unsure about any aspect of the repair, consult a professional plumber: Attempting a repair that is beyond your skill level can lead to further damage and increased costs.

Replacing a bathroom sink tap washer is a relatively straightforward DIY task that can save you money and enhance your bathroom's functionality. By following these steps and tips, you can successfully fix a leaky faucet and restore your sink to its former glory.
