Have you ever turned off your mixer tap fully, only to find that it persistently drips or leaks? This common issue not only wastes water but can also be a frustrating nuisance around the home. In this post, we'll explore why mixer taps begin to drip or leak and provide you with some professional insight on how to address this problem.
Understanding the Mixer Tap Mechanics
Mixer taps blend hot and cold water, allowing you to control both the temperature and flow with one or two handles. Inside these taps are cartridges or washers that control water flow. When you turn the tap handles, these components either block or allow water passage. As simple as it may seem, several issues with these components can cause your tap to leak or drip.
Common Causes of Dripping Mixer Taps
The primary reason for a dripping mixer tap is usually wear and tear on the valve or washer. Over time, these small parts undergo a lot of pressure, eventually leading to deterioration. Here’s a deeper insight into these problems:
1. Worn Out Washer: In traditional taps, a rubber washer forms a water-tight seal. Frequent use can wear this part down.
2. Faulty Ceramic Disc Cartridge: Modern mixer taps often use ceramic cartridges. These can crack or wear, causing a drip.
3. Improper Installation: Sometimes, leaks result from not fitting the tap correctly. This might be misaligned parts or overtightened connections.
How to Spot the Problem
First, determine whether the leak is coming from the spout or the base of the tap. A spout leak typically indicates a problem with the internal mechanism (washer or cartridge), whereas a base leak might suggest an issue with the tap’s fitting or a worn O-ring.
DIY Tips to Fix a Dripping Mixer Tap
Fixing a dripping mixer tap can often be a straightforward DIY task. Here’s how you can attempt it:
- Turn Off the Water Supply: Always start by turning off the water at the mains. Don’t rely on isolation valves as they might not be fully reliable.
- Plug the Sink: Avoid small parts like screws falling down the drain.
- Disassemble the Tap: Carefully remove the handle and cover. Each tap varies, so have your mobile device handy to take pictures as you go.
- Replace the Washer or Cartridge: Identify if you have a washer or cartridge system and replace the faulty part. You can usually find replacements at your local hardware store.
Remember, take your time to understand the tap’s assembly before you start disassembling. Missteps here can cause further issues.
When to Call a Professional
If you’ve replaced the washer or cartridge and the tap still drips, or if you're uncomfortable with DIY, it might be time to call a professional. Some tap designs can be complex, and an experienced plumber can ensure a correct and safe repair. Additionally, if you notice multiple dripping taps at home or weak water flow, it could indicate broader plumbing issues.
Prevention Tips for Long-Term Care
Regular maintenance can prevent future tap problems. Here are a few tips:
- Regularly clean your taps to prevent build-up of limescale, which can affect tap performance.
- If your home has hard water, consider installing a water softener to protect plumbing fixtures.
- Annually check the integrity of the tap’s components.
Conclusion
A dripping mixer tap is usually a result of worn-out internal components such as washers or cartridges. Identifying the exact cause of the leak is essential for effective repair. While replacing these parts is often a simple DIY task, don't hesitate to contact a professional if the problem persists or if the repair seems beyond your skill level. Regular maintenance and attentive use can help extend the life of your taps, keeping them functional and efficient for years to come. Remember, conserving water is not only good for the environment but also for your water bills. So take action early when you spot a drip!
