## How to Change a Sink Faucet Kitchen
Changing a sink faucet is a relatively simple plumbing repair that can be completed in about an hour or two. With the right tools and a little bit of patience, you can easily replace your old faucet with a new one.
### Tools and Materials You’ll Need
* Adjustable wrench
* Basin wrench
* Plumber’s putty
* New faucet
* Teflon tape
### Step-by-Step Instructions
**1. Turn off the water supply.**
The first step is to turn off the water supply to your sink. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to shut off the water.
**2. Disconnect the old faucet.**
Once the water is turned off, you can disconnect the old faucet. Use an adjustable wrench to loosen the nuts that hold the faucet in place. Be careful not to overtighten the nuts, as you could damage the faucet or the sink.
Once the nuts are loose, you can pull the old faucet out of the sink. Be careful not to spill any water from the faucet.
**3. Clean the sink.**
Once the old faucet is removed, take a few minutes to clean the sink. Use a sponge or cloth to wipe away any dirt or debris. You can also use a mild cleanser to clean the sink if needed.
**4. Apply plumber’s putty.**
Before you install the new faucet, you need to apply plumber’s putty to the base of the faucet. Plumber’s putty is a pliable material that helps to seal the faucet and prevent leaks.
To apply plumber’s putty, simply roll out a small piece of putty into a snake-like shape. Then, wrap the putty around the base of the faucet, overlapping the ends by about 1/2 inch.
**5. Install the new faucet.**
Once the plumber’s putty is in place, you can install the new faucet. Insert the faucet into the hole in the sink and tighten the nuts by hand. Then, use an adjustable wrench to tighten the nuts further, but be careful not to overtighten them.
**6. Connect the water supply lines.**
Once the faucet is in place, you need to connect the water supply lines. The hot water line is usually red or orange, and the cold water line is usually blue or green.
To connect the water supply lines, simply screw the lines onto the corresponding valves under the sink. Tighten the nuts by hand, and then use an adjustable wrench to tighten them further.
**7. Test the faucet.**
Once the water supply lines are connected, you can test the faucet. Turn on the water supply valves and let the water run for a few minutes. Check for any leaks around the base of the faucet or the water supply lines.
If you find any leaks, tighten the nuts or bolts until the leak stops.
**8. Finish up.**
Once you’ve tested the faucet and made sure there are no leaks, you can finish up. Wipe away any excess plumber’s putty from around the base of the faucet, and install the faucet handle.
Your new faucet is now installed and ready to use!
### Tips

* Be careful not to overtighten the nuts or bolts when installing the new faucet.
