whilst testing a house that had sustained severe water damage (but dehumidifiers had been in for a month so it was dry now) from a burst pipe, i really needed to go to the toilet(house was in the middle of nowhere) but there was no water in the toilet, so i thought i'd just turn the stoptap back on. still no water, so i go out onto the drive to see if i can find the main stoptap, found it, turned it on, went back to the house to see it raining in from the hole in the ceiling, bloody water everywhere so the bloody pipe had not been fixed! ran back 100m to turn it off, got back to the house, bloody soaked. quickly mopped it up with rockwool and parked some dehumidifiers on there to dry it out and went home to the toilet. by the time i got back it looked dry so i got away with it, and i heard through the grapevine they done some tests to see how it was drying out the next day and there was water trapped in the stud walls and they had to rip them out because if it was still there after a month then it was never gonna dry out. whoops
