Have you ever been kept awake by the repetitive sound of a dripping tap? It’s not only a nuisance, but it can also be the sign of underlying plumbing issues that might need attention. Understanding why your tap is dripping is the first step to solving the problem effectively and ensuring it doesn’t lead to higher water bills or further damage.
The Anatomy of a Tap
Most taps function through a simple mechanism involving a handle, a spindle, a washer, and a valve seat. When you turn the tap handle, the spindle moves, allowing the washer to either block or release water flow by pressing against the valve seat. This system is efficient but prone to wear and tear over time.
Common Causes of a Dripping Tap
1. Worn-Out Washer
The washer endures constant friction as it seals against the valve seat, which can cause it to wear out or become damaged. This is the most common cause of a dripping tap. A simple test is to feel if the tap’s handle has become unusually easy to turn; a loose feel often indicates a worn washer.
2. Damaged Valve Seat
The valve seat can become corroded or encrusted with mineral deposits from the water. This damage can prevent the washer from forming a watertight seal, thus leading to a drip.
3. Improper Washer Installation
If a washer is not the correct size or is not installed properly, it won’t seal correctly. This sometimes occurs during DIY replacements or after a maintenance service.
4. High Water Pressure
Occasionally, dripping taps can result from excessively high water pressure pushing water through even when the tap is turned off.
Spotting the Problem
To determine the cause of the leak, start by identifying the type of tap: is it a compression, ball, disc, or cartridge type? Compression taps, which are characterised by separate handles for hot and cold water, are more prone to issues with washers.
DIY Fixes You Can Try
- Replacing the Washer: This is the most straightforward repair if you have a compression tap. First, ensure the main water supply is turned off. Next, remove the tap’s handle and spindle to access the washer. Replace the old washer with a new one of the same size and material.
- Cleaning the Valve Seat: Use a valve seat wrench to unscrew the valve seat. Clean any debris or build-up and check for damages. If the damage is extensive, it might be wise to replace the seat altogether.
- Adjusting Water Pressure: If high water pressure is suspected, you might need to adjust the pressure-reducing valve where your main water line enters the house.
When to Call a Professional
If you’ve tried the above fixes and your tap continues to drip, or if the tap has multiple issues like a damaged valve seat along with a faulty washer, it’s time to call a professional. Plumbing is intricate, and further DIY attempts might exacerbate the problem.
Long-Term Prevention
1. Regular Maintenance: Scheduling regular check-ups with a plumber can help catch issues early before they turn into dripping taps.
2. Water Softener: If you live in an area with hard water, consider installing a water softener to reduce mineral build-up in your plumbing systems.
3. Quality Parts: When replacing parts, opt for high-quality components that might be more resistant to wear and longer-lasting.
Conclusion
A dripping tap might seem like a small annoyance, but it can signify the need for a closer look at your plumbing system. By understanding what causes tap leaks, you can address the problem more effectively, save on water bills, and prevent future issues. While many tap problems can be resolved with a bit of DIY, don't hesitate to call in a professional if the issue persists or is beyond your comfort zone. Remember, taking care of your taps not only saves water but also preserves the integrity of your home’s plumbing infrastructure.
