<human>:  How do I unclog a sink drain?
<bot>: The first step to unclog a sink drain is to remove any debris or blockages in the drain. You can use a plunger, a plumbing snake, or a commercial drain cleaner. If the clog is still not cleared, then you may need to disassemble the drain trap to remove the clog. Once the clog is removed, you can reassemble the drain and run hot water down the sink to help flush out any remaining debris.
