<human>:  How to fix a leaking faucet?
<bot>: First, turn off the water supply to the faucet. Then decide if the faucet needs to be replaced or if you can repair it. If you can repair it, you will need to remove the handle, inspect and repair the parts, such as the springs and seals, and then put the handle back on and turn the water supply back on. Test the faucet to see if it's fixed. If not, you may need to replace the faucet.
