About the WaterCop System

The WaterCop System is designed to detect leaks at predetermined locations, and automatically shut off the water supply to help effectively reduce the chances of major water damage. A WaterCop system will provide your home with round-the-clock indoor flood protection. It works with wired and wireless flood sensors, wall switches, and most home security/automation systems.

WaterCop offers homeowners many benefits:

  • Added property protection and peace of mind
  • Potential insurance savings (discounts or credits)
  • Integration with home security and automation systems
  • 24/7 protection and conservation while you're home or away

Flood damage and losses related to plumbing problems can lead to higher home insurance costs and possibly the loss of affordable coverage altogether. The WaterCop system, when properly installed and maintained, offers a proven method to effectively reduce the chance of catastrophic flooding related to plumbing.

WaterCop Systems are ideal protection for:

  • Single-family residences
  • Multi-family residences
  • Vacation homes and villas
  • Rental homes and apartments
  • Senior living homes and centers
  • Offices
  • Dormitories
  • Condominiums
  • Laundry businesses

System Components

The WaterCop System is composed of three basic parts:

  • WaterCop Electric Actuator Motor, the main system control unit.
  • Ball valve, connected to the Electric Actuator Motor, automatically turns off your water supply when any flood sensor detects water.
  • Flood sensors, which detect water from a leak or overflow, house a wireless radio transmitter that sends a signal to the WaterCop Motor to turn off your water supply.

How the System Works

Flood sensors constantly monitor their selected areas for accumulating moisture. When a leak is detected, a sensor sends a wireless radio frequency signal to the WaterCop motor, instructing it to activate the valve to shut off the water supply to the home. Once shut, the WaterCop valve will remain closed until it is manually reset. The flood sensors are battery-powered, enabling them to be located anywhere a leak is likely to occur, or where water might cause damage.

As the brains of the system, the motor features a built-in wireless receiver with user adjustable digital security codes, which allows additional nearby WaterCop systems to operate independently. The motor also has auxiliary low voltage contacts with a modular RJ-45 interface socket for direct connection to optional WaterCop accessories, or for integration with a third-party home security or automation system using standard Cat5 computer cabling.
