Materials You'll Need:

Turn off the water supply: Start by turning off the main water supply to your home. This will prevent water from flowing into the sink while you are working.
Disconnect the drain line: Locate the drain line that connects the sink to the drainpipe. Disconnect the drain line by unscrewing it from the sink.
Install the shut-off valve: Place the shut-off valve in the middle of the drain line. Tighten the nuts on the shut-off valve using an adjustable wrench.
Reconnect the drain line: Screw the drain line back onto the sink. Tighten it securely with a basin wrench.
Apply plumber's putty: Apply a bead of plumber's putty around the base of the shut-off valve. This will help to seal any gaps and prevent leaks.
Turn on the water supply: Turn the main water supply back on. Check for any leaks around the shut-off valve. If you find any leaks, tighten the nuts on the valve or add more plumber's putty.
