The kitchen is located on the floor above. I tried running the garbage disposal for the kitchen sink but nothing happened. The downstairs toilet is flushing and working fine. I'm not sure what the source of the problem is, as both downstairs sinks clogged up at the same time. Is there any way I can determine which sink is the culprit? I tried running a drain snake through them both but to no success.Just figured I'd ask here before calling a plumber. Thanks. via /r/DIY http://bit.ly/2IzqODL
