<human>:  How do I unclog a sink drainage pipe?
<bot>: First, you should try to unclog the sink by using a plunger. Begin by placing the plunger over the sinkhole and pressing it down firmly. If the clog isn't removed with the plunger, you can try to unclog it with a snake, a long flexible metal tool that you can insert down the drainpipe to break up the clog. If this doesn't work, you may need to remove the sink trap to access the pipe and manually remove the clog.
