Have you ever noticed that annoying drip that just won't quit even after you've firmly turned off your tap? It's not just a mere annoyance; a dripping tap can waste more water than you might think and potentially lead to higher water bills and unnecessary wear on your plumbing system. This issue is often caused by a worn-out tap washer - a small but crucial component in the sealing mechanism of your taps.
Understanding why this happens and how to address it can save you from the frustration and the stealthy hike in utility costs. In this post, we'll walk through everything you need to know about why tap washers fail and how to replace them effectively. Plus, we'll touch on recognizing when this is a job for a professional.
What is a Tap Washer, and What Does it Do?
A tap washer is a small disc, typically made of rubber or a rubber-like material, that sits inside the tap mechanism. Its primary role is to create a water-tight seal to prevent water from leaking out when the tap is turned off. Over time, however, tap washers can degrade due to constant pressure, exposure to water, and general wear and tear.
Identifying the Signs of a Worn-Out Tap Washer
The most obvious sign of a worn-out tap washer is a dripping tap. If you hear water dripping when the tap is supposed to be closed, it's a clear indicator. Another sign might be a tap that's difficult to turn off completely, often requiring extra pressure to stop the water flow.
Tools You Will Need for a Washer Replacement
Before diving into the replacement, make sure you have the appropriate tools. Typically, you'll need:
- An adjustable spanner or wrench
- A screwdriver (check if your tap handle is held by a flathead or Phillips screw)
- Replacement washers (ensure these are the correct size and type for your tap)
- Possibly some penetrating oil, if the tap components are stiff or corroded
Steps to Replace a Tap Washer
1. Turn Off the Water Supply: Before starting any work on your taps, it’s crucial to turn off the water supply to prevent flooding. You’ll usually find the isolation valve under the sink or basin.
2. Remove the Tap Handle: This is generally secured by a screw, often hidden under a decorative cap on the tap handle. Use your screwdriver to remove this screw and then lift off the handle.
3. Unscrew the Headgear Nut: With the handle off, you’ll see the top part of the tap mechanism known as the headgear. Unscrew this using your wrench. If it's tight, apply some penetrating oil and let it sit for a few minutes before trying again.
4. Replace the Washer: Once the headgear is off, you can see the old washer at the base of the stem. Remove this washer — it might simply pull off, or you could need to unscrew it. Place the new washer onto the stem (or screw it in, depending on the design).
5. Reassemble the Tap: Attach the headgear, replace the handle, and secure everything using the screws you removed earlier.
6. Test Your Work: Turn the water supply back on and test the tap. There should no longer be a drip, and the tap should turn off smoothly and completely.
When to Call a Professional
While tap washer replacement is a relatively simple task, there are times when it’s wise to call a professional. If you encounter corroded parts, or if the tap continues to leak after you've replaced the washer, there may be more significant issues at play, such as damage to the tap seat or valve. A professional plumber can address these problems and ensure that your plumbing remains in top shape.
Preventing Future Washer Wear
To extend the life of your new tap washer, consider the following:
- Regularly clean your taps to prevent grit or mineral buildup that can damage the washer.
- Be gentle when turning taps on and off; excessive force can distort washers.
Conclusion
Replacing a tap washer is a practical skill that can save you from the annoyance and expense of a dripping tap. By following the steps outlined above, you can tackle this problem with confidence. Remember, while many minor plumbing issues are manageable DIY projects, don’t hesitate to call in a professional when the situation is beyond your comfort zone.
