A tiny, inexpensive device is often the only thing standing between a minor drip and a catastrophic basement flood. The GE Personal Security Water Leak Alarm acts as a silent sentry in those high-risk zones like laundry rooms, garages, or near hot water tanks where you simply can't monitor the floor 24/7. I found the setup process remarkably painless. Because it is battery-operated and uses a simple peel-and-stick application, you don't need to mess with any complicated wiring or electrical work.
