## How to Fix a Kitchen Sink Faucet Drip
A dripping kitchen sink faucet is a common problem that can be easily fixed with a few simple steps. Here’s how to do it:
### Tools and Materials
* Adjustable wrench
* Plumber’s tape or pipe sealant
* Replacement washer or O-ring (optional)
### Step-by-Step Instructions
**1. Turn off the water supply:**
* Locate the shut-off valves under the sink and turn them clockwise to turn off the water supply to the faucet.
**2. Open the faucet:**
* Open the faucet to release any remaining water pressure in the line.
**3. Remove the aerator:**
* Unscrew the aerator, which is located at the tip of the faucet, by hand or using a wrench. If there is a lot of mineral buildup, you may need to use vinegar or a commercial cleaning solution to loosen it.
**4. Inspect the washer or O-ring:**
* Check the washer or O-ring, which is a small rubber or plastic seal located inside the aerator or the base of the faucet handle. If it is worn, cracked, or damaged, it will need to be replaced.
**5. Replace the washer or O-ring (if necessary):**
* If the washer or O-ring needs to be replaced, remove the old one and insert the new one in its place. Make sure it is seated properly.
**6. Apply plumber’s tape or pipe sealant:**
* Wrap plumber’s tape or apply pipe sealant around the threads of the aerator or the base of the faucet handle, depending on where the leak is coming from. This will help create a seal and prevent leaks.
**7. Reinstall the aerator:**
* Screw the aerator back onto the faucet. Tighten it securely by hand or using a wrench.
**8. Turn on the water supply:**
* Turn on the shut-off valves under the sink to turn on the water supply to the faucet.
**9. Check for leaks:**
* Turn on the faucet and check for any leaks. If there is still a leak, you may need to tighten the aerator or the base of the faucet handle more securely.
### Additional Tips
* If the leak is coming from the base of the faucet handle, you may need to replace the cartridge inside the faucet. This is a more complex repair that should be performed by a plumber.
* If you have a two-handle faucet, you may need to replace both the hot and cold water washers or O-rings.
* If the leak is coming from the connection between the faucet and the sink, you may need to tighten the mounting nuts or replace the gasket.
* If the leak is coming from the water supply lines, you may need to tighten the connections or replace the lines.
### Conclusion
Fixing a kitchen sink faucet drip is a relatively easy task that can be completed in a few minutes with the right tools and materials. By following these simple steps, you can save yourself the time and expense of calling a plumber.
