Have you ever noticed a persistent dripping sound echoing from your kitchen or bathroom sink? That subtle but incessant drip can be more than just a minor annoyance; it could signify a worn-out tap washer that needs attention. Replacing a tap washer is one of the more straightforward plumbing tasks, but understanding its nuances can save you from future headaches and unnecessary water wastage.
What Causes Tap Washers to Fail?
Tap washers endure constant pressure and frequent use, making them susceptible to wear and tear. Primarily made from rubber, these small discs can harden over time, losing their flexibility and ability to form a tight seal. Factors such as water quality and over-tightening of the tap can accelerate this deterioration.
Identifying a Faulty Tap Washer
The most common symptom of a faulty tap washer is a leaking or dripping tap. If you close your tap firmly and still notice water trickling through, it's a reliable indicator that the washer might be compromised. Additionally, if turning the tap handle feels notably stiff or if the leak worsens when the tap is in use, these are further signs that the washer needs replacing.
Tools You Will Need
Before you begin the replacement process, assemble the following tools:
- Adjustable spanner or wrench
- Screwdriver (flathead or Phillips depending on your tap)
- Replacement washer (ensure it's the correct size for your tap)
- Cloth to protect the tap's finish
Shutting Off the Water Supply
Safety first. Ensure the mains water supply is turned off before you start working. This prevents any water from coming through while you’re disassembling the tap, which keeps your workspace dry and safe.
Dismantling the Tap
First, plug your sink to avoid losing any small components down the drain. Next, most taps will have a decorative cap on top of the handle; gently pry this off with your screwdriver to expose the retaining screw. Remove this screw and carefully lift off the tap's handle.
Below the handle, you’ll see a nut that holds the tap’s headgear in place. Use your adjustable spanner to loosen and remove this nut. Once removed, you can access the old washer seated at the base of the headgear.
Replacing the Washer
Remove the old washer. It might be screwed in place or simply slotted on a pin. Evaluate the condition of the seating and the stem for any grit or mineral deposits – clean these areas thoroughly. Place the new washer onto the stem or screw it in, ensuring it sits snugly without warping.
Reassembling the Tap
Follow the disassembly steps in reverse. Replace the headgear and tighten the nut to secure it - be firm but avoid over-tightening as this can damage the new washer. Reattach the handle and the decorative cap.
Testing Your Work
Once everything is reassembled, turn the water supply back on and test the tap. No water should leak when the tap is off, and it should flow smoothly when turned on. If there are any leaks, slightly tighten the headgear nut, but if the problem persists, there may be another issue at play.
Knowing When to Call a Professional
If replacing the washer does not resolve the dripping, or if the tap’s components are extensively corroded or damaged, it might be time to call a professional. Complex issues underlying simple symptoms can often go unnoticed without the trained eye of a seasoned tradesperson.
Preventative Maintenance
To extend the life of your tap washers, avoid over-tightening the tap handles – turning them beyond the point of resistance can quickly wear out the washers. Regularly cleaning your taps can also prevent the build-up of limescale and debris, which can exert additional pressure on the washers.
Conclusion
While a dripping tap might be tempting to ignore, addressing it promptly with a simple washer replacement can prevent escalated water bills and potential water damage. This task not only offers a practical introduction to basic plumbing but also instils a greater understanding of household water systems.
If this guide has helped you fix a dripping tap, consider examining other taps in your home. Regular maintenance and timely repairs are key to a well-functioning plumbing system.
Feel confident about tackling this and similar issues yourself, but remember, there's no substitute for professional expertise when repairs go beyond the basics.
