Mine is completely my fault - I was a resident surgeon and had been on call the entire weekend and decided to do water changes when I got off - I lived in Manhattan on the 17th floor in a shoebox sized studio with a 150, 135, 65 and 72 bow front .
I was in the midst of a water change when I passed out and woke up to 6 inches of water on the floor and immediately freaked out . I used a pile of dirty scrubs and every towel or absorbent article of cloth that I had to attempt to mop-up the mess.
after I had got the majority of it up , I got a knock on the door from security and asked if everything was alright as there had been a leak that had gone down 3 floors.
I profusely apologized and told them I had accidentally over filled the “bath tub”. As a side note, there no fish tanks allowed in the apartment. I kept expecting to get an eviction notice over the next month, but It it never came somehow.
