We went on a 10 day vacation. Upon returning found a 4 X 8 foot part of the ceiling in the laundry room had collapsed due to the sheet rock getting water soaked. The section is below the toilet in a bathroom. When we went to the bathroom nothing was happening. No broken pipe, nothing running. Small amount of water at end of room near the toilet. Toilet inlet pipe is not leaking, toilet works fine. Bathroom ceiling is fine It did rain very hard for a few days here. Home is raised ranch and entire back of house is above ground. Did leave water on while we were gone (probably a mistake). The puzzle is where did the water come from and why do we not see a continuing problem? The section where the ceiling gave way is where a lot of pipes for the bathroom run but the water on the floor above implies the water came from the bathroom and not a pipe (also there is no drip) Could the water have run down the outside of the vent pipe for the plumbing? If it did how come we have water in the bathroom?
TIA for any ideas.
