## How to Replace Your Kitchen Sink Plumbing
Replacing the plumbing under your kitchen sink is a relatively simple task 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
* Basin wrench
* Bucket
* Channel locks
* Flashlight
* Gloves
* Hacksaw
* Pliers
* Putty knife
* Screwdriver
* Sponge
* 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 located under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to close them.
#### 2. Disconnect the Water Lines
Once the water supply is turned off, you can disconnect the water lines from the sink. Use an adjustable wrench to loosen the nuts that connect the water lines to the sink. Be careful not to overtighten the nuts, as this can damage the water lines.
#### 3. Remove the Old Sink
Once the water lines are disconnected, you can remove the old sink. First, use a putty knife to remove any old caulk around the sink. Then, use a screwdriver to remove the screws that hold the sink in place. Once the screws are removed, you can lift the sink out of the cabinet.
#### 4. Clean the Countertop
Once the old sink is removed, you can clean the countertop. Use a sponge and some dish soap to remove any dirt or debris.
#### 5. Install the New Sink
Now you can install the new sink. First, place the sink in the cabinet and align it with the holes for the water lines. Then, use a screwdriver to insert the screws that hold the sink in place.
#### 6. Connect the Water Lines
Next, you need to connect the water lines to the new sink. First, apply some Teflon tape to the threads of the water lines. Then, screw the water lines into the sink. Be careful not to overtighten the nuts, as this can damage the water lines.
#### 7. Turn On the Water Supply
Once the water lines are connected, you can turn on the water supply. Slowly turn on both shut-off valves and check for leaks. If you see any leaks, tighten the nuts on the water lines until the leaks stop.
#### 8. Finish Up
Once you’ve checked for leaks, you can finish up the installation. First, apply a bead of caulk around the edge of the sink. Then, use a sponge to smooth out the caulk. Finally, let the caulk dry for 24 hours before using the sink.
### Tips
* If you’re not comfortable replacing the plumbing under your kitchen sink, you can hire a plumber to do it for you.
* Be sure to turn off the water supply before you start working on the plumbing.
* Use Teflon tape on all of the threaded connections to prevent leaks.
* Check for leaks after you’ve turned on the water supply.
* If you see any leaks, tighten the nuts on the water lines until the leaks stop.
