<human>:  Can you tell me how to replace a broken faucet?
<bot>: To replace a broken faucet, start by turning off the water supply valves underneath the sink. Disconnect the lines from the old faucet and remove it from the sink. Install the new faucet into the appropriate holes in the sink and re-connect the water supply lines. Test the new faucet and turn the valves back on when you're finished.
