It is in my bedroom which is next door to the bathroom, and on the other side of the bedroom outside the house is the sprinkler pipe...The wetness occupies maybe 2 feet by 2 feet and it is starting to warp the floorboards. I don't think it's coming from the walls or the ceiling because that's dry, and what's weird is the spot just sort of starts on the floor about at least one foot away from any wall in the room. Help. Do you think it's a slow leak or something? I noticed it Sunday night and it was a maybe like six inches by one foot and it's slowly getting bigger.
