Ever turned off your mixer tap only to notice that it continues to drip or even run a thin stream of water? This minor annoyance is not just a waste of water; it can actually lead to bigger plumbing issues over time, such as increased water bills or even water damage. Let's get into what might be causing your mixer tap to drip and provide some guidance on how to fix it.
If you're facing a dripping mixer tap, you might think it's a simple wear and tear issue. However, several factors could be at play here. Understanding these can save you time and money and prevent future drips.
Understanding Mixer Tap Mechanics
Mixer taps blend hot and cold water streams, providing water at your desired temperature. They typically function through either a cartridge, compression valve, or a ceramic disc mechanism. The type of mechanism your tap uses can influence how you approach repairs.
Common Causes of Drips
1. Worn Out Washer or O-Ring: These are typically found in traditional compression valve mixer taps. The rubber washer or O-ring can wear out over time, causing water to leak.
2. Damaged Cartridge or Ceramic Discs: In more modern mixer taps, cartridges or ceramic discs control the flow and mix of the water. These can become damaged or clogged with debris.
3. High Water Pressure: Sometimes, the issue isn't with the tap itself, but with the water pressure in your home. High pressure can cause ongoing dripping.
Step-by-Step Guide to Fixing a Dripping Mixer Tap
Tools You Will Need:
- Adjustable wrench
- Screwdrivers
- Replacement washer or cartridge (depending on your tap)
- Allen keys
Identifying the Type of Mixer Tap
Before you can fix a drip, you need to identify what type of mechanism your mixer tap uses. This information will typically be found in the manufacturer's manual.
Turning Off the Water Supply
Always start by turning off the water supply. This can typically be done at the shut-off valves under the sink. Turn on the tap to release any remaining water in the pipes.
Disassembling the Tap
Most mixer taps have a decorative cap on the handle, which you can usually pry off gently with a screwdriver. Underneath, there will be a screw that holds the handle in place. Remove this screw and take off the handle.
Inspecting the Interior
With the handle off, you'll be able to see the top of the cartridge or the valve. Use your wrench to unscrew and carefully remove this component.
Replacing Faulty Parts
Examine the cartridge, washer, or ceramic discs for any signs of wear or damage. If they look worn, take the component to your local hardware store to find an exact replacement. Replacing these parts is generally straightforward—fit the new part in the same place as the old one.
Reassembling the Tap
Once the new part is in place, reassemble the tap by reversing the disassembly steps. Turn the water supply back on and check if the drip has stopped.
When to Call a Professional
If you've replaced the part and the drip persists, or if the tap is damaged in some way (like a crack in the fixture), it's time to call a professional plumber. Some issues, especially related to water pressure or internal pipe damage, are best left to the experts.
Prevention Tips
Keeping your mixer tap in good condition involves regular maintenance. Periodically clean your tap, check for signs of wear on the components, and manage your home's water pressure if necessary. Simple actions like not turning the handles too vigorously can prolong the life of your tap.
Conclusion
A dripping mixer tap can be more than just an annoyance; it can signify that something is not quite right with your tap’s internal mechanics. With the right tools and a bit of know-how, most homeowners can manage simple repairs like replacing a washer or cartridge. Remember, for more complex issues, especially those involving the main water supply or internal damages, consulting with a professional plumber is advisable. Take action today to stop the drip and ensure your mixer tap functions efficiently for years to come.
