Before starting any plumbing work, it’s crucial to ensure safety. Turn off the water supply to the sink and open the faucet to release any remaining water. Place a bucket beneath the sink to catch any water that might leak.
Step-by-Step Guide:
1. Remove the Old Valve
- Use an adjustable wrench to loosen the packing nut that connects the valve to the water supply pipe.
- Carefully remove the old valve by unscrewing it counterclockwise.
2. Clean the Connection
- Clean the threads on the water supply pipe and the new valve using a rag or brush.
- Apply a few wraps of Teflon tape clockwise around the threads to create a watertight seal.
3. Install the New Valve
- Hand-tighten the new valve onto the water supply pipe.
- Use an adjustable wrench to further tighten the valve, but avoid overtightening.
4. Connect the Handle
- Attach the handle to the valve stem and tighten it securely.
5. Reconnect the Water Supply
- Turn on the water supply to the sink.
- Check for any leaks around the valve. If there are leaks, tighten the packing nut further using an adjustable wrench.
6. Test the Valve
- Turn the valve on and off several times to ensure it’s working properly.
- Check for any leaks and make adjustments as needed.
7. Clean Up
- Remove the bucket and any rags or towels you used.
- Run water through the sink for a few minutes to flush out any debris.
