Two of interest:
1. Had to step out of a meeting w/ a customer overseas when my wife texted me to say there was an usually loud noise coming from the mancave (i.e. fish room). Turns out the HOB overflow lost its syphon and the return pump was running dry. Had her turn off the return pump switch until I could return the following week.
2. Called my wife during a power outage and, for some reason, asked her to check on the mancave. She walks in and states "the floor is wet". I frantically told her to get out of the room, go to the breaker box, and shut down everything! I immediately left work to resolve it. Turns out it was a back-syphon issue with my return line. It was plumbed too deep into the tank...which I had propped up higher...but it knocked loose during a recent cleaning and I hadn't realized. Probably overflowed about 10 gallons.
