Have you ever turned off your tap only to hear the persistent, annoying drip that continues long after you've walked away? It's a common issue in many homes, and not only is it irksome, but it can also waste a significant amount of water over time. Before you resign yourself to the background soundtrack of a leaking tap, let's delve into why this might be happening and how you can rectify the situation.
Why do taps leak?
A leaking tap often stems from an issue with the tap's internal mechanisms — primarily the washer or the valve seat. Over time and through normal use, these components can wear out or become damaged, causing water to escape even when the tap is in the 'off' position.
Identifying the source of the leak
To begin, you need to determine whether the leak is coming from the spout or the base of the tap. A leak from the spout typically suggests a worn-out washer. If the leak is emanating from the base where the tap meets the sink, the problem could be with the O-ring, another component that can wear out over time.
What you'll need to fix a dripping tap
Preparing to fix a leaky tap doesn’t require many tools and is something you can handle with basic DIY skills. You'll need:
- An adjustable wrench
- Screwdrivers (both flathead and Phillips)
- Replacement washers and O-rings (ensure these are the correct size and type for your tap)
- Plumber's tape
Shutting off the water
Before you start your repair, it's crucial to turn off the water supply to the tap. You’ll typically find the valve under the sink or, in some cases, a main shutoff valve for your home. Once you’ve turned off the water, turn the tap on to drain any water left in the pipes and to depressurise the system.
Disassembling the tap
Most taps have a decorative cap on top of the handle. Gently prise this off with a flathead screwdriver to expose the screw that holds the handle in place. After removing this screw, you should be able to lift off the handle, exposing the internal parts of the tap.
Replacing the washer or O-ring
With the handle off, you will see a nut securing the stem. Using your wrench, loosen and remove this nut. Be mindful of the order and orientation of any components you remove. At this stage, you can replace the washer or O-ring. These are usually found at the bottom of the stem for washers, or around the stem for O-rings. If you notice any wear or damage on these parts, replace them with the new ones you've got ready.
Reassembling the tap
Once you’ve replaced the necessary parts, it’s just a matter of putting everything back together. Reverse the steps you took to disassemble the tap, making sure everything is tight and secure. It’s usually helpful to apply some plumber's tape around the thread of the stem before screwing the nut back on, as this can help prevent future leaks.
Testing your work
Once you’ve reassembled the tap, turn the water supply back on and test the tap. If everything went smoothly, the drip should have ceased. If it hasn’t, you may need to disassemble again and double-check that everything has been put back correctly and that the washer or O-ring is seated properly.
When to call a professional
While many dripping taps can be handled with a few tools and a bit of patience, there are times when it's best to call in a professional. If you've attempted a fix but the leak persists, or if the leak is accompanied by other plumbing issues, a qualified plumber can ensure that there are no further underlying issues.
Preventing future leaks
Regular maintenance is key to preventing future tap leaks. Periodically check the condition of the tap's washer and O-ring and replace them if they begin to show signs of wear. A general check over your home’s taps every few months can save you a lot of hassle down the line.
Conclusion
Fixing a dripping tap is not only satisfying in ridding yourself of an irritating noise but also beneficial for your water bill and the environment. With a bit of know-how and the right tools, you can tackle this common home maintenance issue confidently. Remember, if you ever feel out of your depth, there's no shame in calling a professional — sometimes, it's the safest and most efficient option.
