Have you ever been kept awake by the relentless drip, drip, drip of a leaky tap? It's not only a nuisance but could also be a sign of a worn-out washer, leading to water wastage and an increased water bill over time. In this blog post, we'll dive into the common issue of a dripping tap, what causes it, how to diagnose it yourself, and the steps involved in replacing a tap washer. Additionally, we'll discuss when it's time to call in a professional plumber and provide some preventive tips to keep your taps in top condition.
Understanding Why Taps Drip
The relentless dripping of a tap usually stems from issues with the internal mechanisms, primarily the washer. A washer is a small, typically rubber piece that forms a water-tight seal in compression fittings, preventing water from passing through when the tap is turned off. Over time, washers can wear out, stiffen, or degrade, losing their ability to form this seal effectively.
Identifying the Problem
Initially, you might need to confirm that a faulty washer is indeed the culprit. Signs include:
- A tap that continues to drip after being firmly turned off.
- A squeaking sound when turning the tap, indicating the washer might be worn out.
- Visible wear or residue on the valve seat, accessible by dismantling the tap (done during washer replacement).
Safe DIY Washer Replacement Steps
Before attempting any plumbing repair, ensure the main water supply is turned off. This simple step prevents water from gushing out when you remove the tap components.
1. Tools and Materials: You will need a screwdriver, an adjustable spanner, and possibly some penetrating oil if components are stiff. Ensure you have the correct replacement washer – these come in various sizes and materials.
2. Disassembling the Tap: Most taps require removing a decorative cap on the handle to expose a screw that holds the handle in place. After removing this screw, lift off the handle. Then, use the spanner to loosen the packing nut that hides the valve stem, revealing the faulty washer at its base.
3. Replacing the Washer: Remove the old washer, taking note of its orientation and size. It's essential to match the replacement exactly to avoid further leaks. Once the old washer is out, it’s good practice to check the valve seat within the tap. A worn valve seat could damage the new washer. If it's rough or uneven, it might need professional resurfacing.
4. Reassembling the Tap: With the new washer securely in place, reassemble the tap by reversing the disassembly steps. Ensure all connections are tight but do not over-tighten, as this might damage the new washer or the tap itself.
5. Testing Your Work: Once everything is reassembled, turn the water supply back on and test the tap. There should be no leaks, and the action should feel smooth and secure.
When to Call a Professional
While many people are comfortable performing the above steps, there are times when calling a professional is advisable:
- If the tap continues to drip despite a new washer being installed, the issue might lie deeper, such as with a damaged valve seat.
- If disassembly reveals corroded or broken parts that aren't easily replaceable.
- When you're not comfortable carrying out the replacement yourself.
Preventive Tips for Long-Term Maintenance
To prolong the life of your taps and prevent future leaks:
- Regularly clean your taps to prevent a buildup of limescale and debris, which can wear out washers more quickly.
- Slightly turn taps off; overtightening can deform the washer.
- Consider installing ceramic disc taps, which are more durable and less prone to dripping.
Conclusion
A dripping tap is more than just an annoyance; it's a plumbing issue that can cost you money if not addressed promptly. By understanding the function and replacement of a tap washer, you're equipped to tackle the problem head-on or make an informed decision about when to call in the professionals. Regular maintenance and timely repairs will keep your home’s plumbing in excellent condition, ensuring peace of mind and the efficient use of water.
