We've had a plumbing emergency. The roommate found a wet spot on her carpet. Tracing it back to the wall, we found the sheet rock was wet on both sides of that wall. A pipe in the wall was leaking. 

To get access to the pipe, the plumber had to remove the hot water tank. So no hot water for the next few days.

Right now there are blowers and dehumidifiers drying things out. Fortunately the husband and the room mate are traveling, so they won't have to endure most of the restoration.
