Command Large Motorized Valves to Stop Leaks

The WaterCop Classic Interface for 1-1/2-in and 2-in Large Valves with 12VDC Actuator is specifically designed to integrate with large-sized WaterCop valves (sold separately). This indoor control unit connects to WaterCop motorized valves and leak sensors (sold separately) to command your WaterCop Leak Detection System. When a connected leak sensor sends an alert that it detects water, the Interface sends a command to connected motorized valve to close to prevent further leakage. The interface can also connect to third-party home automation and security systems via CAT5 cable to send alerts when it changes the open/close status of connected valves.

  • Receives wireless signals from wireless flood sensor(s)
  • Automatically activates the shut-off valve upon leak detection
  • On/off valve control buttons allow for manual operation
  • Color-coded LED indicates current valve position
  • Includes 20-foot power cord for any standard outlet
  • Optionally integrates into a security/automation system

WaterCop works around the clock monitoring potentially vulnerable areas in your home for plumbing leaks and flooding. When a leak is detected, the WaterCop system sends a signal to close the main supply valve. The WaterCop Classic system supports third-party integration with additional devices such as lights, buzzers, auto dialers, or security/automation systems to further alert and notify property owners and that the WaterCop system has detected unwanted water been activated.
