Have you ever been kept up at night by the persistent drip-drip of a tap? Not only is a dripping tap annoying, but it can also be surprisingly wasteful, potentially leading to higher water bills and undue strain on your plumbing system. This post delves into the common causes of a dripping tap, how to fix them, and when you might need to call in a professional.
Understanding the Causes of a Dripping Tap
A faucet doesn't start dripping without reason. Several factors could be at play, and pinpointing the exact cause can help you choose the best repair method. Here are the most likely culprits:
Worn Out Washer
The washer on a tap forms a water-tight seal, preventing water from leaking out when the tap is turned off. Over time, these washers can wear out or become stiff and brittle, losing their ability to seal properly.
Improper Washer Installation
Sometimes, even a new washer can cause dripping if it's not the correct size or isn't installed properly.
Corroded Valve Seat
The valve seat is where the spout and tap body meet. If this becomes corroded or covered in mineral deposits, it won't provide a smooth surface for the washer to seal against, leading to drips.
O-ring Issues
O-rings are small, typically rubber rings placed around the valve stem that stop water from leaking around the handle. If these become loose or worn out, they can cause the tap to drip.
High Water Pressure
In some cases, dripping taps can be caused by water pressure being too high, which forces water through even when the tap is off.
Spotting the Problem
To determine what’s causing your tap to drip, you’ll need to do a bit of investigative work:
1. Listen and Look: Examine where the tap is dripping. Is it from the spout or around the handles? This can help you determine if the issue might be with the washer or the O-ring.
2. Check Water Pressure: If your taps only drip at certain times (like at night), it might be due to high water pressure.
Fixing a Dripping Tap
Replacing the Washer:
Most commonly, replacing the worn out washer or correcting its installation solves the problem. Here’s a safe way to replace a washer:
1. Turn off the Water Supply: Always turn off your home's water supply before attempting any repairs.
2. Plug the Drain: Use a sink plug or a rag to block the drain. This prevents any small parts from disappearing down the drain.
3. Dismantle the Tap: Use a wrench to unscrew the tap’s headgear and reveal the valve. In some taps, you may need to remove a decorative cap and unscrew a retaining nut.
4. Replace the Washer: Remove the old washer and replace it with a new one that matches exactly in size and type. Ensure it’s seated well.
5. Reassemble the Tap: Put everything back together and turn the water supply back on. Check for leaks.
Addressing Other Issues:
For O-ring or valve seat issues, the process may involve replacements similar to changing a washer, but you might need specific tools or parts specific to your tap model. If in doubt, consult the manual or manufacturer’s guidelines.
When to Call a Professional
If you've tried the above fixes and your tap still drips, or if the dripping quickly returns, it could be indicative of a deeper issue within your plumbing system. This is particularly true if you suspect the problem is related to high water pressure or internal pipe damage.
Preventing Future Drips
Regular maintenance of your taps can help prevent issues before they start. Periodically check and replace worn-out parts, and consider installing a pressure regulator if high water pressure is a problem in your area. Additionally, softening your water can minimise the risk of mineral buildup, which often leads to plumbing issues.
Conclusion
Addressing a dripping tap promptly not only saves water but can prevent more significant damages to your plumbing system. Simple washer replacements and O-ring checks can be done safely at home. However, don't hesitate to contact a plumbing professional if the problem persists or if you're unsure about the repair process. Remember, keeping your taps in good working order is not only good for your peace of mind but also beneficial for your wallet in the long run.
