-Is the dripping faucet driving you crazy? Before you call a plumber or replace it, you may be able to fix it by replacing a small part. Different faucets require different fixes depending on style and brand. Often, the cause of the dripping is a worn out part that is easily replaced. An older faucet may need a new rubber washer while newer models may require new seats and springs, a new cartridge, or a new stem. If you're unsure, your local hardware store or the faucet manufacturer can help. Start by shutting off the water supply under the sink. Turn on the faucet and drain the line. Cover the drain with a cloth to catch any small parts you may drop while you work. To see the parts you will need to replace, use an Allen wrench to loosen the handle screw and remove the handle. Unscrew the cap with an adjustable wrench. Tape the jaws of your wrench with painter's tape, so you don't scratch the faucet's finish. This faucet requires removing the metal stem and ball to remove the faulty seats and springs. Use the Allen wrench to remove these parts from inside the faucet. Take the originals with you to the hardware store to ensure you buy the correct replacement part. It's also smart to compare how much the replacement part will cost in relation to a brand new faucet. Some parts can cost almost as much as new faucet. Using the Allen wrench, insert the new seat and spring into the faucet. Reassemble, turn the water back on, and with any luck, the drip is gone.
