<human>: How can I tell if I have a clogged drain in my bathroom?
<bot>: One way to tell if you have a clogged drain is to check the water level of your sink. If it's low, then there may be a clog somewhere. You can also try pouring a mixture of baking soda and vinegar down your drain. This should help break up any clogs. If that doesn't work, you might need to call a plumber for further assistance.
