Remove the handle cap using a Phillips or flathead screwdriver.
Use an Allen wrench to loosen the screw holding the handle in place.
Pull the handle straight up to detach it from the faucet body.
Check the O-rings or washers located around the base of the handle. Replace any worn or damaged ones.
Reassemble the handle, applying plumber's tape to the base's threads.

Fixing Spout Leaks

Inspecting the washers or seals within the aerator and replacing them if necessary.
Reinstalling the aerator and tightening it securely.
