Guide to Fixing a Leaky Tap
Step 1 - Turn Off the Water Supply
Before you begin any repair work, it's crucial to shut off the water supply to prevent potential flooding. Locate the water shut-off valve, typically situated under the sink. Turn the valve clockwise until it's fully closed. This action stops the water flow to the tap, allowing you to work safely.
Step 2 - Disassemble the Faucet
Start by removing the tap handle. Look for a small screw at the back of the handle and unscrew it using an appropriate screwdriver. If the screw is stubborn, apply a small amount of penetrating oil and wait a few minutes before trying again. Once the screw is removed, lift off the handle.
Next, locate the packing nut. This large nut sits just below where the handle was. Use an adjustable spanner to loosen and remove it. With the packing nut off, you can now twist out the spindle. This is the component that controls water flow when you turn the tap.
Step 3 - Inspect and Replace the Washer
Examine the removed components carefully to identify the source of the leak. In most cases, a worn-out washer is the culprit. You'll find the washer at the base of the spindle. It may be pressed in place or held by a small nut.
Remove the old washer and take it to a hardware store to ensure you get an exact replacement. Fit the new washer securely in place. If the washer isn't the issue, inspect the valve seat for damage. A damaged valve seat may require replacement or regrinding.
Step 4 - Reassemble the Faucet
With the new washer in place, it's time to put everything back together. Start by reinserting the spindle. Ensure it's properly aligned and seated. Next, reattach the packing nut. Tighten it firmly with your adjustable spanner, but be careful not to overtighten as this can damage the components.
Finally, replace the tap handle. Align it correctly and secure it with the screw you removed earlier. Ensure all parts are tightened securely to prevent future leaks.
Step 5 - Turn On the Water Supply and Test
Once reassembly is complete, it's time to restore the water supply. Turn the shut-off valve counterclockwise to allow water flow. Open the tap slowly and check for any leaks around the handle, base, or spout. If water flows smoothly without any drips, you've successfully fixed your leaky tap.
Additional Tips and Considerations
Protecting the Tap During Repair
To avoid scratches and maintain the tap's finish, wrap a cloth around it before using tools. This precaution also prevents the tap from rotating while you're loosening or tightening components.
Using the Right Tools
Having the correct tools is essential for a successful repair. An adjustable spanner or pipe grips are crucial for most steps. If you need to replace the valve seat, a seat wrench is indispensable. Invest in quality tools to make the job easier and prevent damage to the tap.
Preventing Parts from Falling Down the Drain
Before starting the repair, plug the sink drain. This simple step prevents small parts like screws or washers from being lost if accidentally dropped. It can save you significant time and frustration during the repair process.
Common Issues and Solutions
Leaks Around the Handle
If you notice water seeping around the handle after repair, the tap's nut packing may be faulty. Remove the handle again and inspect the packing. If it's worn or damaged, replace it with a new one to ensure a watertight seal.
Faulty Valve Seat
A damaged valve seat can cause persistent leaks even after replacing the washer. In this case, you'll need to either replace the valve seat using a seat wrench or use a seat grinder to resurface it. This process requires precision and may be best left to a professional if you're unsure.
