Ever had that annoying drip, drip, drip sound from your mixer tap that seems to echo through the house at the quietest of hours? Not only is it irksome to the ears, but it's also wasteful and can lead to higher water bills over time. If this is a problem you're currently facing, you're probably keen to understand why it's happening and how you can fix it without necessarily calling in a professional right away.
Understanding Why Mixer Taps Drip
A dripping mixer tap is a common issue in many households. At the heart of this problem are usually the internal components of the tap – primarily the washer or the ceramic cartridge. Over time, these parts can wear out or become damaged due to regular use, leading to a persistent drip. Hard water areas can exacerbate this wear as mineral deposits build up, further impairing the tap's functionality.
Identifying the Problem
Before you can fix a dripping mixer tap, it’s crucial to identify where the problem lies. Is the tap dripping from the spout or is it leaking from the base? Drips from the spout typically suggest a problem with the tap’s washer or cartridge, whereas leaks from the base can indicate a faulty O-ring or seal.
Tools You'll Need
To tackle this repair, you’ll need a few basic tools:
1. An adjustable spanner
2. Screwdrivers (both Phillips and flat-head)
3. Replacement washers or a ceramic cartridge (depending on your tap model)
4. An Allen key (if necessary for your tap model)
5. Plumber's tape
Turn Off the Water Supply
Before you start any work on your mixer tap, it’s imperative to turn off the water supply. This might mean shutting off the valve under the sink or, in some cases, turning off the main water supply to your home if you cannot isolate the tap.
Disassembling the Tap
Start by removing the decorative cap on the tap's handle, usually accessible by gently prying it off with a flat-head screwdriver. Underneath, you'll find a screw that holds the handle in place — unscrew this. Once the handle is off, use your adjustable spanner to unscrew the packing nut, exposing the inner valve. If your mixer tap utilizes a ceramic cartridge, you’ll see this component once the nut is removed.
Replacing the Faulty Part
With the valve or cartridge exposed, carefully remove it. If you’re dealing with a washer, inspect it for wear or stiffness and replace it if necessary. For ceramic cartridges, it’s usually best to replace the entire unit as they can be difficult to repair. Be sure to take the old washer or cartridge with you to a plumbing supply store to find an exact match.
Reassembling the Tap
Once the new washer or cartridge is ready, reverse the disassembly steps. Place the new part into the valve, reattach the packing nut, put the handle back, and secure it with the screw you removed earlier. Don’t forget to replace the decorative cap.
Testing Your Work
After everything is reassembled, turn the water supply back on and test the tap. There should no longer be a drip. If the tap still drips, you may need to disassemble it again and check if the washer or cartridge is properly seated or if another component might be causing the leak.
When to Call a Professional
While many mixer tap issues can be resolved with a simple washer or cartridge replacement, some problems might be beyond a simple DIY fix. If you’ve replaced the necessary parts and the tap continues to drip or leak, it might be time to call a professional. This could indicate a more complex issue with the plumbing that requires specialist tools and expertise.
Prevention Tips
To prevent future issues with your mixer taps:
- Regularly clean your taps to avoid mineral build-up, especially in hard water areas.
- Gently operate the taps without excessive force to reduce wear and tear on internal components.
- Consider installing a water softener if you live in a hard water area to protect your plumbing fixtures.
Conclusion
Fixing a dripping mixer tap is often a straightforward task that requires minimal tools and a bit of patience. By understanding the underlying causes and following the steps outlined, you can not only save water but also extend the life of your taps. However, don’t hesitate to consult with a professional if the problem persists, as some plumbing issues can be more complex than they initially appear. Keep your home’s plumbing in top shape by tackling these minor repairs promptly and efficiently.
