Replacing a tap washer is a straightforward DIY task. Here’s a step-by-step guide to help you through the process:
Tools and Materials Needed:
- Adjustable wrench or pliers
- Screwdriver (flathead and/or Phillips)
- New washer (make sure it’s the correct size)
- Cloth or towel
- Bowl or bucket (to catch water)
- Vinegar or a descaling solution (if needed)
Step-by-Step Guide:
Step 1: Turn Off the Water Supply
- Locate the water supply and close the valve to stop the water supply to the property.
- Open the tap inside the house to drain remaining water and relieve pressure.
Step 2: Remove the Tap Handle
- If there are decorative caps on the tap, gently pry them off with a flathead screwdriver.
- Use the appropriate screwdriver to remove the screws holding the handle in place.
- Carefully pull the handle off the tap.
Step 3: Disassemble the Tap
- Use an adjustable wrench or pliers to loosen and remove the retaining nut or collar that holds the tap mechanism in place.
- Once removed, you should see the washer at the base of the tap.
Step 4: Replace the Washer
- Take out the old washer. It may be held in place by a screw or just fit onto a stem.
- Clean the area where the washer was seated. If there’s any buildup, use vinegar or a descaling solution to clean it.
- Place the new washer onto the tap stem. Ensure it fits snugly.
Step 5: Reassemble the Tap
- Reattach the retaining nut or collar and tighten it securely (but don’t overtighten).
- Replace the tap handle and secure it with the screws.
- If applicable, snap the decorative caps back into place.
Step 6: Turn the Water Supply Back On
- Slowly turn the shut-off valves back on to restore the water supply.
- Check for leaks by turning on the tap.
Step 7: Test the Tap
- Turn the tap on and off a few times to ensure it operates smoothly.
- Inspect for any leaks around the base of the tap.
Tips:
- Always take the old washer with you to ensure you purchase the correct replacement.
- If the tap continues to leak after replacing the washer, there may be other issues that need addressing, such as a damaged valve seat.
By following these steps, you should be able to replace your tap washer easily and effectively!
