I guess it was bound to eventually happen. I've been using a DIY ATO for over four years now and it finally failed me. The bottom float switch became stuck in the "on" position and the backup switch was also stuck, which emptied about 8 gallons into my sump overflowing my floor. Of course this happened while I was away but I managed to clean up most of it though a few gallons made it down into my neighbors unit down below. Their damage is minimal and their home owners insurance will cover it. Thankfully Note to self, don't wait five years before cleaning the switches
