How can I fix a leaking hose bib in my outdoor faucet?

To fix a leaking hose bib on your outdoor faucet, you can start by turning off the water supply to the faucet. Next, unscrew the handle and stem of the hose bib to access the washer. Replace the washer with a new one and reassemble the hose bib. Turn the water supply back on to check if the leak is fixed. If the leak persists, you may need to replace the entire hose bib.
