## How to Demo a Kitchen Sink
Replacing a kitchen sink is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can easily remove your old sink and install a new one.
### Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
– Adjustable wrench
– Basin wrench
– Channel locks
– Plumber’s putty
– Utility knife
– Caulk gun
– Silicone caulk
– New kitchen sink
– New faucet (if desired)
– Garbage disposal (if desired)
### Step-by-Step Instructions
#### 1. Turn Off the Water Supply
The first step is to turn off the water supply to your kitchen sink. You can do this by locating the shut-off valves under the sink and turning them clockwise. If you do not have shut-off valves, you will need to turn off the main water supply to your home.
#### 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 faucet. Be careful not to overtighten the nuts, as this can damage the water lines.
#### 3. Disconnect the Drain Line
Next, you need to disconnect the drain line from the sink. Use a basin wrench to loosen the nuts that connect the drain line to the sink. Be careful not to overtighten the nuts, as this can damage the drain line.
#### 4. Remove the Old Sink
Once the water lines and drain line are disconnected, you can remove the old sink. Carefully lift the sink out of the countertop and place it on the floor. Be sure to support the sink with your hands so that it does not fall and break.
#### 5. Clean the Countertop
Once the old sink is removed, you can clean the countertop. Use a damp cloth to wipe away any dirt or debris. If there is any old caulk around the sink, use a utility knife to remove it.
#### 6. Apply Plumber’s Putty
Before you install the new sink, you need to apply plumber’s putty to the underside of the sink. Plumber’s putty is a sealant that helps to create a watertight seal between the sink and the countertop. To apply plumber’s putty, simply roll it into a rope and place it around the edge of the sink.
#### 7. Install the New Sink
Once the plumber’s putty is in place, you can install the new sink. Carefully lift the sink into place and set it on the countertop. Be sure to align the sink with the holes for the water lines and drain line.
#### 8. Reconnect the Water Lines
Once the sink is in place, you can reconnect the water lines. Use an adjustable wrench to tighten the nuts that connect the water lines to the faucet. Be sure to tighten the nuts securely, but do not overtighten them.
#### 9. Reconnect the Drain Line
Next, you need to reconnect the drain line to the sink. Use a basin wrench to tighten the nuts that connect the drain line to the sink. Be sure to tighten the nuts securely, but do not overtighten them.
#### 10. Install the Garbage Disposal (Optional)
If you are installing a garbage disposal, now is the time to do it. Follow the manufacturer’s instructions to install the garbage disposal.
#### 11. Install the Faucet
If you are installing a new faucet, now is the time to do it. Follow the manufacturer’s instructions to install the faucet.
#### 12. Caulk the Sink
Once the sink, faucet, and garbage disposal are installed, you can caulk the sink. Caulk helps to create a watertight seal between the sink and the countertop. To caulk the sink, simply apply a bead of silicone caulk around the edge of the sink. Use your finger or a caulk tool to smooth out the caulk.
#### 13. Turn On the Water Supply
Once the caulk is dry, you can turn on the water supply to your kitchen sink. Check for any leaks around the sink, faucet, and drain line. If you find any leaks, tighten the nuts or bolts that are causing the leak.
