## How to Replace a Kitchen Sink Faucet
Replacing a kitchen sink faucet is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.
### Tools and Materials You’ll Need
* New kitchen sink faucet
* Adjustable wrench
* Basin wrench
* Plumber’s putty
* Teflon tape
* Utility knife
* Flashlight (optional)
### Step-by-Step Instructions
#### 1. Turn Off the Water Supply
The first step is to turn off the water supply to your kitchen sink. There are typically two shut-off valves located under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are fully closed.
#### 2. Disconnect the Water Lines
Once the water supply is turned off, you can disconnect the water lines from the old faucet. Use an adjustable wrench to loosen the nuts that connect the lines to the faucet body. Be careful not to overtighten the nuts, as this can damage the lines.
#### 3. Remove the Old Faucet
Once the water lines are disconnected, you can remove the old faucet. There are typically two nuts that hold the faucet in place, one on the top of the sink and one on the bottom. Use a basin wrench to loosen the nuts and remove the faucet.
#### 4. Clean the Sink Surface
Once the old faucet is removed, take a moment to clean the sink surface around the faucet holes. This will help to ensure a good seal for the new faucet.
#### 5. Apply Plumber’s Putty
Apply a ring of plumber’s putty around the base of the new faucet. This will help to create a watertight seal between the faucet and the sink.
#### 6. Wrap Teflon Tape Around the Water Lines
Wrap a few turns of Teflon tape around the threads of the water lines. This will help to prevent leaks when you reconnect the lines.
#### 7. Install the New Faucet
Insert the new faucet into the sink holes. Make sure that the faucet is properly aligned and that the plumber’s putty is evenly distributed around the base.
#### 8. Tighten the Mounting Nuts
Tighten the mounting nuts on the top and bottom of the sink. Do not overtighten the nuts, as this can damage the faucet or the sink.
#### 9. Reconnect the Water Lines
Reconnect the water lines to the new faucet. Use an adjustable wrench to tighten the nuts until they are snug.
#### 10. Turn On the Water Supply
Slowly turn on the water supply to your kitchen sink. Check for leaks around the faucet and the water lines. If you find any leaks, tighten the nuts further.
### Troubleshooting Tips
* If you are having trouble removing the old faucet, you may need to use a penetrating oil to loosen the nuts.
* If the new faucet is not fitting properly, you may need to adjust the mounting nuts or use a shim to level the faucet.
* If you are experiencing leaks after installing the new faucet, check to make sure that the nuts are tight and that the plumber’s putty is properly applied.
### Conclusion
Replacing a kitchen sink faucet is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.
