Where Dirty Water Should Not Be

I came home 5 weeks ago to a icky water scene where gross water came up my kitchen sink and flooded my kitchen and some of my living room. I currently have no kitchen, but hopefully that will change next week.
  1. Your sink
  2. Your pots and pans that are in your cabinets
  3. Your counters
  4. Your kitchen floor
  5. Your carpet
  6. Your carpet padding
  7. EVERYWHERE. Dirty water with shmutz and other people's food scraps should not come up your kitchen sink. Ever.
