When I saw the ceiling has water draping in ground level kitchen, and damaged the ceiling drywall., my first thought is the the pipes broken in upper level kitchen. The water was actually come from dishwasher in upper level, and it happened that the tile floor in that area was not properly grouted.
So I have to 1: shut down water to dishwater. 2: buy the dishwasher parts the leaking, 3: grout the floor tiles, 3: replace the dishwasher parts, 4: fix the ceiling drywall.
