Full Answer

Begin the repair by turning off the water to the faucet. Locate the shut-off valves where the pipes exit the walls, and turn the valves counterclockwise. Cover the sink drain with a washcloth to prevent parts from falling into it. Cover the jaws of pliers with duct tape to prevent scratches.

Use a flat-blade screwdriver to pry off the decorative caps from the handles. Use the appropriate screwdriver to remove the retaining screws and handles from the faucet. Use the tape-covered pliers to remove the packing nut from the cold-water side of the faucet, place the handle back on the faucet stem, and turn it in the direction to open the valve. Continue turning to remove the stem.

The compression washer is on the opposite end of the stem from the handle and held in place with a brass screw. Coat the new washer with nontoxic plumber's grease and place it in the stem. If the repair kit includes new brass screws, use them to replace the existing ones and reverse the steps to install the stem. Repeat the process with the hot-water side of the unit.
