<human>: How do I know if I have a clogged sink drain?
<bot>: To determine if you have a clogged sink drain, check to see if water is not draining as quickly or easily as usual. If the sink is slow to fill up after being used, it could be due to a clogged pipe. You can also try using a plunger to dislodge any blockage and then check for an improvement in drainage. Additionally, you may want to look into replacing your sink's drain assembly.
