Fixing a leaky faucet is a common plumbing issue that you may be able to tackle yourself. Here are the general steps to follow:
Turn off the water supply to the faucet. Look for a valve under the sink and turn it clockwise to shut off the water.
Remove the handle. Depending on the type of faucet, you may need to use a screwdriver or an Allen wrench to remove the handle. You may need to pry off a cover to access the screw.
Remove the cartridge or valve stem. Use pliers to remove the cartridge or valve stem from the faucet body. If you're not sure which type of faucet you have, take the old parts to the hardware store to find the right replacement. BONUS: Most faucets have a life-time warranty, so call the manufacture and ask them if they will send you free replacement.
Replace any worn or damaged parts. Check the O-rings, washers, and other parts for damage or wear. Replace any parts that are not in good condition.
Reassemble the faucet. Put the faucet back together in the reverse order that you took it apart. Turn on the water supply and test the faucet to make sure it no longer leaks.
