Steps to Replace a Moen Bathroom Sink Drain Stopper:

Turn Off Water: Begin by turning off the water supply to the sink. Locate the shut-off valves beneath the sink and turn them clockwise.
Remove Stopper Assembly: Using an adjustable wrench, carefully loosen the tailpiece nut that connects the stopper assembly to the sink drain. Once loose, lift the stopper assembly straight up.
Inspect Washer: Examine the rubber washer on the old stopper assembly. If it's damaged or worn, replace it with a new one.
Apply Plumber's Putty: Apply a thin layer of plumber's putty around the base of the new stopper assembly.
Install Stopper Assembly: Insert the new stopper assembly into the sink drain hole. Manually tighten the tailpiece nut as much as possible.
Tighten with Wrench: Using the adjustable wrench, further tighten the tailpiece nut by turning it clockwise.
Insert Allen Wrench: Locate the set screw on the underside of the stopper assembly. Insert the Allen wrench and tighten the screw until snug.
Check for Leaks: Turn on the water supply and check for any leaks around the stopper assembly. If necessary, adjust the tailpiece nut or Allen screw to ensure a watertight seal.

Additional Tips:

If the old stopper assembly is stuck or difficult to remove, use a flashlight to locate the set screw. Loosen the screw to free the stopper.
Use a utility knife to trim any excess plumber's putty that may have squeezed out during installation.
For pop-up drain stoppers, the Allen screw may be located on the side of the stopper assembly. Refer to the manufacturer's instructions for specific details.
If you encounter any difficulties or have any safety concerns, do not hesitate to contact a qualified plumber for assistance.
