Handyman thinks lack of use in the basement lead to a clog that built up over the years. Years before Airbnb they were renting out the apartment through the local tourism department because there aren’t a lot of hotels here but it’s a scenic area. But they stopped as they got older so now it only sees use for a couple weeks twice a year when we come. But when we come with 3 people it puts more pressure on the waste line and starts backing up, and finally became a problem tonight.

He thinks there’s a drain in the floor of our bedroom and somebody just put down laminate flooring overtop of it. There should be a drain somewhere but he doesn’t see one, and given the water intrusion there as the other drains were backing up that’s his best guess. Won’t know for sure until he pulls up the floor this week, though.
