Human: How can I fix a leaking faucet? Assistant: 
You can start by turning off the water supply under the sink and then checking to see if the pipes need to be tightened or replaced. If the leak is coming from the faucet, you can replace the washers, O-rings, and other seals that may have deteriorated over time. Additionally, you may need to replace the valve cartridge depending on what type of faucet you have.
