Experiencing a dripping mixer tap can be more than just an annoyance; it can lead to higher water bills and potential damage to your kitchen or bathroom. Leaks often arise from a failure within the tap's mechanism — typically a worn out washer or a problem with the ceramic cartridge. This blog will guide you through identifying the problem, executing a DIY fix, and knowing when it’s time to call in a professional.
When you notice a leak, it’s crucial to address it promptly to avoid further complications. By understanding the basics of mixer tap construction and maintenance, you can effectively manage minor repairs and extend the life of your fixtures.
Understanding Mixer Taps
Mixer taps blend hot and cold water, allowing the user to control the output’s temperature and flow with either a single handle or dual controls. These are common in kitchens and bathrooms and rely on internal components that can wear out over time, causing leaks.
Identifying the Source of the Leak
1. Location of the Drip
- Spout: Indicates issues with the tap valve or cartridge.
- Base of the Tap: Suggests a problem with the O-ring or the seal between the tap and the sink.
Distinguishing where the water is coming from can help you understand which parts might need your attention.
Tools You Will Need
Gather the necessary tools before you begin:
- Adjustable spanner
- Screwdrivers (both Phillips and flat-head)
- Replacement parts (washers, O-rings, or a ceramic cartridge if required)
- Cloth to protect the tap’s finish
- Allen keys (for some modern taps)
Step-by-Step Repair Instructions
If the Leak Is From the Spout
1. Turn Off the Water Supply: Always start by turning off the water at the mains to avoid a watery mess.
2. Remove the Tap Handle: This is usually secured with a screw, often hidden under a decorative cap that you can gently pry off with a flat-head screwdriver.
3. Dismantle the Tap Headgear: Use an adjustable spanner to loosen and remove the headgear nut, revealing the valve or ceramic cartridge underneath.
4. Replace the Faulty Component:
- For traditional taps with washers: Replace the washer at the base of the valve.
- For taps with ceramic cartridges: It’s often best to replace the entire cartridge as it can be challenging to fix a damaged ceramic part.
5. Reassemble the Tap: Make sure all parts are secure but not overtightened as this can damage the new components.
If the Leak Is From the Base
1. Remove the Tap from the Sink: This might require loosening the nuts under the sink using a basin wrench.
2. Replace the O-ring or Washer: These are located around the base of the tap where it meets the sink. Examine the old O-ring or washer and replace it with one of the same size and thickness.
3. Reinstall the Tap: Ensure it’s fixed tightly enough to prevent future leaks but again, avoid overtightening.
Testing Your Work
Once everything is reassembled, turn the water supply back on and check the tap for leaks. Operate the tap a few times and observe any escaping water. If it continues to leak, you may need to disassemble again and check if the components are properly aligned and securely fastened.
When to Call a Professional
While many mixer tap issues can be resolved with DIY repairs, some situations call for professional intervention:
- If the leak persists after your repair attempts
- If there’s significant damage to the tap or plumbing
- If you're not confident in performing the repairs safely
Maintaining Your Mixer Tap
Regular maintenance can prevent common issues:
- Regularly clean your tap and avoid harsh chemicals that can corrode tap components.
- Check the tightness of the tap’s fittings periodically as they can loosen over time.
Conclusion
Fixing a leaking mixer tap often involves simple replacement of internal components like washers, O-rings, or cartridges. By following the steps outlined, you can manage minor repairs yourself. Remember, if the problem continues or you're unsure about tackling it, a professional plumber can ensure the repair is done safely and effectively. Plus, regular maintenance and timely repairs will prolong the life of your mixer taps, maintaining their functionality and appearance.
