I registered an account to ask this questions, and hopefully someone on this forum can help me out. I live on the first floor of a 2 story apartment building. It seems that the water from upstairs is coming up in our kitchen sink. Our bathroom is fine, and nothing comes up when we flush the toilet or take a shower. I drew up a diagram of how I think it works, but this is just how I make sense of it in my head. I am no plumber by any means, or have any working knowledge of how plumbing systems work, so bear with me on the drawing. Please let me know what you guys think, or if you have any questions. Thank you.
