<human>: How do I know if I have a clogged drain in my kitchen sink?
<bot>: To determine if you have a clogged drain in your kitchen sink, check the water flow. If it is slow or not draining at all, then you may have a clog. You can also use a plunger to try and dislodge any blockages, but if that doesn’t work, you may need to call a plumber.
