You don't have don't have to shell out a hefty payment to a plumber to fix that annoying leaky faucet. Learn how to fix a leaky faucet with this helpful guide. Fixing a dripping faucet in your home can save energy, water, and money.

Identify the Faucet Type

Identify the type of faucet you have before you start any repairs on it. Disc faucets have two ceramic discs encased in a cylinder with neoprene seals in the cylinder bottom. There are really only two things that can go wrong in a disc faucet: Dirt or slime buildup around the seals may cause the faucet to leak or the discs inside the cylinder may be damaged. Always try cleaning the cylinder before replacing it. If the discs in the faucet are cracked, you must replace the entire cylinder.

Turn off the water to the faucet before you begin the repair.
