## How to Change a Kitchen Sink Fixture
Replacing a kitchen sink fixture 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
* Adjustable wrench
* Channel-lock pliers
* Basin wrench
* Utility knife
* Plumber’s putty
* Teflon tape
* New kitchen sink fixture
* Spray bottle filled with water
* Rags
### Step 1: Turn Off the Water Supply
Before you begin working on the sink, turn off the water supply valves under the sink. These valves are usually located near the base of the faucet.
### Step 2: Disconnect the Water Lines
Use the adjustable wrench or channel-lock pliers to loosen the nuts that connect the water lines to the faucet. Be careful not to overtighten the nuts, as this can damage the water lines.
### Step 3: Remove the Faucet
Once the water lines are disconnected, you can remove the faucet from the sink. To do this, reach under the sink and loosen the nuts that hold the faucet in place. Once the nuts are loose, you can lift the faucet out of the sink.
### Step 4: Clean the Sink Hole
Before you install the new faucet, take a moment to clean the sink hole. Use a utility knife to remove any old plumber’s putty or sealant from the hole. You can also use a spray bottle filled with water to rinse the hole.
### Step 5: Apply Plumber’s Putty
Apply a bead of plumber’s putty around the base of the new faucet. The plumber’s putty will help to create a watertight seal between the faucet and the sink.
### Step 6: Install the Faucet
Insert the new faucet into the sink hole. Be sure to align the faucet with the holes for the water lines. Tighten the nuts that hold the faucet in place.
### Step 7: Connect the Water Lines
Connect the water lines to the faucet. Be sure to wrap the threads of the water lines with Teflon tape before tightening the nuts.
### Step 8: Turn On the Water Supply
Turn on the water supply valves under the sink. Check for leaks around the faucet. If you notice any leaks, tighten the nuts that hold the faucet in place.
### Step 9: Finish Up
Once you’re satisfied that there are no leaks, you can finish up the installation process. Insert the handles into the faucet and tighten the screws that hold them in place. You can also connect the spray hose to the faucet, if desired.
### Troubleshooting
If you encounter any problems while changing a kitchen sink fixture, here are a few troubleshooting tips:
* If the faucet leaks around the base, you may need to apply more plumber’s putty.
* If the faucet is loose, you may need to tighten the nuts that hold it in place.
* If the water lines leak, you may need to replace the washers.
With a little patience and these step-by-step instructions, you can easily replace a kitchen sink fixture.
