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.

Our enhanced sensor catches even tiny water traces, so you get an alarm before a drip becomes a disaster. 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.

Features
  • Enhanced sensor for precise detection of smallest water traces
  • Manual reset for added safety after water detection
  • Versatile compatibility with dehumidifiers, aquariums, and washing machines
  • 5-year warranty and exceptional customer support
  • Prevents major flooding and water damage with automatic appliance shut-off
