This is a regular residential bathroom sink. Granted, it's over a 100 year old house with 100 year old plumbing, but still... so nothing goes into this sink except for toothpaste from regular brushing of teeth, that's it. I pour in some liquid plumr, let it sit overnight, and then the water flows fine. For a while. Give it a day or two, and it gets super clogged again. Is the toothpaste causing the clog? I'm a real loss here because I can't think of what is the cause, and how to permanently fix it...
