Yesterday I walked into the living room and it was literally raining. My houseguest had put a 'rag' in the upstairs bathroom sink, turned on the water and forgotten all about it. My couch and a recliner were soaked with almost an inch of water on the wood floor.
Today almost everything is dry. My wood floor has scrapes from me moving everything.
Now I need to find a way to stop this disaster from happening again. If I use Flexseal on my ceiling, the water will just soak into the wood floor and rot it. I'm very tempted to 'paint' the whole bathroom and put a 6" board across the threshold to enclose the whole half bath. Or I could just turn off the water to the sink and remove the line.
