My original RO/DI system was in the kitchen, used for drinking and my tank. I usually either just get a few gallons from the pressure tank at a time for topoff water. When I'm making more than that for water changes, I usually set my alarm watch to make sure I don't overflow. Well, we were going out for my birthday and after chasing my 3-year olds all over to get them into the car, strapped in, etc, I forgot!!!
Came home to find this! The water had overflown. The kitchen floor had soaked through into the basement ceiling, which then came down! The ceiling had to be repaired, the entire carpeting replaced, couch barely salvaged, the kitchen floor is still warped (contractor can't figure out how to fix it without taking up all cabinetry and appliances), the kids' lamb had to be put to sleep
To my wife's credit, my tank and I are still alive! Now I have use a float switch!
