Human: How do you find out if you have a clogged drain? Assistant: 
The first step is to identify the type of clog. You can usually tell by the color and texture of the material that has built up in your drain. If it’s hard or crumbly, then you likely have a blockage caused by grease or food particles. If it’s softer and more liquidy, then you likely have an obstruction caused by soap scum or hair. Once you know what kind of clog you have, you can take steps to fix it. For example, if it’s soap scum, you can try using a mixture of baking soda and vinegar to scrub away the buildup.
