The washer can become hardened, worn or the seat wears, causing the faucet to leak. You can close the faucet tighter to stop the leaking temporarily, but this increases the internal damage to the faucet. To repair the leak, first turn off the water. If there's a shutoff valve beneath the fixture, turn off the water at that point. Otherwise, turn it off at the main house shutoff valve in the basement, utility room, or crawlspace.

It will thread out. Reinstall the handle if you have difficulty turning it (Fig. 1). Clean chips from the faucet cavity, but do not use harsh abrasives or a file. Examine the stem. If the threads are badly corroded or worn, take it to your retailer and get a new stem to match. Clean the stem if it's dirty. Now look at the washer, which is located on the lower end of the stem and held in place by a brass screw. If the washer is squeezed flat or has a groove worn in it, replace it–this should stop any dripping. Take the washer with you to your dealer to ensure an exact match in size and style. If the brass screw is damaged, too, replace it with a new brass screw.
