Around 3 years ago I had a 15 gallon sump (15 gallon glass aquarium) under my 90g that had the side literally blown out by an older glass heater I had put in there to see if it still worked. Lessons learned- just buy new heaters, don't test anything that can explode in an active sump, always have shoes that can withstand glass on the floor ready to go.
My wife and I were watching tv/napping on the couch at 2 in the morning on a Friday night and hear a loud "pop". So here we are at 2 am and we had water pouring everywhere. The tanks are in the kitchen where we have tile floor and a 3/4 inch tall wooden divider that separates the hardwood floors in the living room from the kitchen tile. Luckily that kept the water in the kitchen only.
It was a disaster. I immediately ran to shut off the valve for the overflow to stop the DT from draining out further, then went for the fuse panel to shut off anything in that area (the fuse the heater was on had already popped) and my wife went for every towel we owned. Between headlamps, towels and a wet vac we got it sorted after about 3-4 hours enough to get some sleep then finish drying and damage assessment the next day.
