It’s a common nuisance: the relentless drip, drip, drip of a leaking tap. Not only is it annoying, but a dripping tap can significantly increase your water bill and lead to unnecessary water wastage. Often, the culprit behind this common plumbing issue is a worn or damaged washer. Addressing a faulty washer promptly can save you from more complex and costly repairs down the line.
Understanding Why Washers Fail
Washers are integral to the functioning of your taps. Positioned inside the tap mechanism, they form a water-tight seal preventing water from passing through when the tap is turned off. Over time, washers can deteriorate due to normal wear and tear or can become stiff and lose their flexibility, mainly if they're infrequently used. Factors like water quality and over-tightening of taps can accelerate this degradation.
Identifying the Problem
The first sign of a worn washer is usually a tap that won’t completely halt water flow, no matter how hard it's turned off. You might notice a slow drip or a continuous trickle. In some cases, the tap might also make a screeching sound when turned, indicating that the washer has hardened and is sticking against the valve seat.
Safety First
Before attempting any repair work on your taps, it's crucial to ensure your safety and protect your plumbing. Always start by turning off the water supply to the tap. This is typically done via the isolation valve, often located under the sink or where the plumbing for the tap is accessible. Once the water is off, open the tap to release any remaining water and pressure in the pipes.
Tools You'll Need
To replace a tap washer, you'll need a few basic tools:
- An adjustable spanner or wrench
- A flat-head or Philips screwdriver depending on the screw type in the tap
- Replacement washers
- Possibly some penetrating oil if components are stiff
Step-by-Step Washer Replacement
1. Remove the tap handle – This is usually secured with a screw, sometimes hidden under a decorative cap that you can gently pry off. Remove the screw and lift the handle off.
2. Dismantle the tap mechanism – Use the wrench to unscrew the tap’s covering, also known as the tap bonnet. If it’s stiff, apply some penetrating oil around it and wait a few minutes before trying again.
3. Replace the washer – Once the bonnet is off, you’ll see the stem carrying the faulty washer, typically held in place by another small screw. Remove this, replace the washer with one of the same size and composition, and reassemble the tap.
4. Test your work – Turn the water supply back on and check the tap for leaks. It might take a few minutes for the system to pressurize fully.
When to Call a Professional
While many people are comfortable performing minor repairs like changing a washer, certain situations should prompt you to call a plumbing professional:
- If the tap continues to drip after the washer has been replaced, the issue might be in the valve seat or other parts of the tap mechanism.
- In cases where the tap assembly is old or corroded, disassembling it could cause further damage or require special tools.
- If there are no isolation valves, or if turning off the water supply to your home is required, you might prefer a professional to handle the task.
Long-Term Prevention
To extend the life of your washers and taps:
- Avoid over-tightening them since this can deform the washer more quickly.
- Regularly use all the taps in your home to keep the washers flexible.
- Consider installing a water softener if you live in a hard water area, as mineral buildup can also affect the function of your plumbing.
Conclusion
Fixing a dripping tap caused by a worn washer is a straightforward task that can be satisfying and economically beneficial. Not only does it stop the irritating drip, but it also conserves water and can save money on your water bill. Remember, though, sometimes what seems like a simple fix might uncover more significant plumbing issues, so don’t hesitate to call in a professional if the problem persists or you’re unsure at any point during your DIY plumbing attempt.
By understanding and attending to your home's plumbing needs, you can maintain a more efficient and trouble-free water system.
