Tools and Materials You’ll Need
Before you begin, make sure you have:
- A new faucet (compatible with your sink)
- Adjustable wrench or basin wrench
- Screwdriver
- Plumber’s tape (Teflon tape)
- A bucket or towel
- Plumber’s putty (optional)
- A flashlight or headlamp
- Vinegar or a cleaning product to remove mineral buildup

1. Shut Off the Water
Start by turning off the hot and cold water valves under the sink. Then, open the faucet to release any remaining water and relieve pressure.
Pro Tip:
If you can’t find the shutoff valves or they’re stuck, turn off your home’s main water supply.
2. Disconnect the Supply Lines
Place a bucket or towel under the sink to catch any residual water. Use a wrench to disconnect the water supply lines from the faucet. Keep the washers if they’re still in good condition—or replace them if needed.

4. Install the New Faucet
Insert the new faucet through the mounting holes in your sink. From underneath, secure it with the provided nuts. Hand-tighten first, then use a wrench to finish (be careful not to overtighten). Apply plumber’s putty if recommended by the manufacturer.


5. Reconnect the Water Supply Lines
Reconnect the hot and cold supply lines to the new faucet. Add a bit of plumber’s tape to the threads to ensure a tight, leak-free seal. Tighten with a wrench, but don’t overdo it.
6. Turn the Water Back On and Test
Slowly reopen the shutoff valves under the sink. Turn on the faucet and check for leaks—both around the base and under the sink.
