HydroCheck WaterWatcher Water Sensor Alarm: Prevents major flooding and water damage with automatic appliance shut-off
For homeowners who want to protect their basement or laundry room from unexpected leaks, the HydroCheck WaterWatcher is your first line of defense. It's not just about detecting water; it's about preventing the panic and expense of a flooded floor by automatically shutting off appliances like dehumidifiers or washing machines the moment moisture is sensed.

The manual reset ensures appliances stay off until you've fixed the issue, giving you control. Compatible with aquariums, well pumps, and more, it offers versatile protection with a 5-year warranty for peace of mind.
