Step-by-Step Instructions

1. Turn off the water supply. The first step is to turn off the water supply to the sink. There will be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to shut them off.

2. Disconnect the water supply lines. Once the water supply is turned off, you can disconnect the water supply lines from the sink. Use a wrench to loosen the nuts that hold the lines in place. Be careful not to overtighten the nuts, as this can damage the lines.

3. Remove the old sink. Once the water supply lines are disconnected, you can remove the old sink. First, remove the drain stopper from the sink. Then, lift the sink up and off of the countertop. Be careful not to damage the countertop when removing the sink.

4. Clean the countertop. Once the old sink is removed, take some time to clean the countertop. Remove any old caulk or debris from the surface of the countertop.

5. Apply plumber's putty to the new sink. Before installing the new sink, you need to apply plumber's putty to the bottom of the sink. Plumber's putty is a type of sealant that will help to prevent water from leaking around the sink.

6. Install the new sink. Once the plumber's putty is applied, you can install the new sink. Place the sink on the countertop and align it with the drain hole. Press down on the sink to seat it in place.

7. Connect the water supply lines. Once the sink is installed, you can connect the water supply lines. Hand-tighten the nuts that hold the lines in place. Be careful not to overtighten the nuts, as this can damage the lines.

8. Apply caulk around the sink. Once the water supply lines are connected, you can apply caulk around the sink. Caulk is a type of sealant that will help to keep water from leaking around the sink.

9. Turn on the water supply. Once the caulk is applied, you can turn on the water supply. Check for any leaks around the sink. If you find any leaks, tighten the nuts on the water supply lines or apply more caulk.
