Hoping for some advice with a situation my wife and I had this morning while I was on my way to the office. The upstairs bathroom toilet overflowed. My wife didn't shut it off in time and enough water overflowed to cover the floor of the bathroom. When she went downstairs she could see water leaking from the recessed lighting in the kitchen. She cleaned it all up and opened one of the light fixtures and she said quite a bit of water came pouring out. It's all cleaned up now but I'm wondering, will the water between the walls dry up on it's own? Is this a job for a plumber or will it dry out on it's own? I can't imagine it's any more than 4 or 5 gallons of toilet water that actually went through but who knows. What would you advise I do?
