Apt. 302 Caused This Leak. Wait, I'm Apt. 302.

I live in a 60-year-old building. Recently the kitchen sink drain in my apartment developed a leak. I had no clue, because it was all going on behind the wall. Three stories below in the lobby, they got a very big clue.

So apartments or people, you get to be 60-years-old there will be plumbing issues.
