Removing the Old Shut-Off Valve
With the water supply shut off, you can begin removing the old shut-off valve.
Using an adjustable wrench or basin wrench, loosen the packing nut that holds the valve in place. Then, use needle-nose pliers to remove the old shut-off valve.
Be careful not to damage the surrounding piping or faucet when removing the old valve.
Installing the New Shut-Off Valve
Install the new shut-off valve by tightening the packing nut in a clockwise direction. Make sure it's snug but do not overtighten.
Also, apply some Teflon tape to the threads of the new valve, then hand-tighten the valve.
Finally, turn the water supply back on and test the faucet to ensure the new valve is functioning correctly.
