Have you ever been kept awake at night by the constant drip-drip-drip from your bathroom tap? It’s not just a minor annoyance; a dripping tap can lead to increased water bills and potential long-term damage to your plumbing. Understanding why taps drip and knowing how to address this common issue can save you not just in costs but also prevent potential headaches in the future.
Dripping taps are one of those pervasive problems that many think they can live with but shouldn’t. It’s a symptom of underlying issues that, if left unchecked, could lead to more significant plumbing emergencies.
What Causes a Tap to Drip?
The primary reasons for tap drippage extend from wear and tear of the internal components to more complex water pressure issues. Here are some common causes:
Worn Out Washer
The most common cause of a dripping tap is a worn-out washer. These are small discs attached to the tap's handle, crucial for forming a water-tight seal. Over time, washers can degrade, lose their flexibility, or become dislodged, leading to a persistent drip.
Faulty Tap Cartridge
Modern mixer taps often use cartridges instead of washers. These cartridges control the flow and mix of hot and cold water. Like washers, cartridges can wear out or become damaged, resulting in a drip.
Corroded Valve Seat
The valve seat, which connects the tap and the spout, can become corroded. This corrosion prevents the washer or cartridge from sealing properly which can lead to leaks.
High Water Pressure
Sometimes, the culprit can be your home’s water pressure. If the pressure is too high, water can be forced out through weak points in the tap, causing a drip.
How to Spot a Dripping Tap
Identifying a dripping tap is straightforward:
1. Visual inspection: See if water continues to drip when the tap is turned off.
2. Sound: Listen for the tell-tale dripping noise, which is particularly noticeable during quiet night hours.
DIY Fixes for a Dripping Tap
Replacing the Washer
1. Turn off the water supply to your tap.
2. Plug the drain to prevent small parts from falling down it.
3. Unscrew the tap handle and remove the tap cover to access the valve.
4. Remove the valve and replace the washer, ensuring it’s the correct size and fit.
5. Reassemble the tap and turn on the water supply to check if the drip has stopped.
Replacing the Cartridge
1. Similar steps are involved as with replacing a washer, but you’ll need to purchase a specific cartridge for your tap model.
2. Cartridges must be installed aligned correctly, which might require noting the position of the old cartridge before removal.
Knowing When to Call a Professional
While many tap issues can be resolved with DIY approaches, certain situations should be handled by professionals:
- If the tap continues to drip after you've replaced the washer or cartridge.
- If there is significant corrosion or damage to the tap assembly.
- If adjustments to your water pressure system are needed.
Professional plumbers have the tools and expertise to address these issues without causing further damage to your plumbing.
Long-term Prevention Strategies
Preventing future drips begins with routine maintenance:
- Regularly clean your taps to prevent lime scale build-up.
- Replace washers and cartridges at the first sign of wear.
- Monitor your home’s water pressure.
By incorporating these tips into your household routine, you can extend the life of your taps and minimize future repairs.
Conclusion
Addressing a dripping tap sooner rather than later can save you from more significant plumbing jobs down the line. Simple steps like replacing a washer or cartridge can often be done without professional help. However, don't hesitate to call a plumber if the issue persists or the repair is beyond your comfort level. Regular maintenance and being proactive with potential issues can ensure your taps operate smoothly, keeping your nights silent and your water bills low.
