  • Connect up to 8 sensors

    This controller unit can connect up to 8 water detection sensors, allowing you to cover the whole water pipe area in the house.

  • Easy-operated Controller

    8 LED lights indicating which sensor has detected water. Three buttons give you different choices to interact freely with the controller.

What’s included

  • Ball valve with sound/light alarm
  • Controller module
  • 5V / 1A Transformer
  • 2 pieces of water sensors

Step1: Install the ball valve to the pipe.

To install the ball valve, shut off the main water supply line, turn on a faucet on the water supply line, drain out the remaining water and air in the pipe. Locate the ball valve's position to be installed, use a pipe cutter to cut the sides of the pipe. Put the ball valve into the spliced pipe. Please note that sweat joints/plumber's cement(not included) may be needed to secure the installation. Depending on the type of the pipes, couplers(not included) may also be required to close the installation.

Step2: Mount the control module on the wall.

The control module should be mounted at a location close to the application that is vulnerable to water leakage, and a power outlet is required.

Step3: Make sure the location is damp.

Place and spread the sensors on the ground. Up to 8 sensors are supported. For best performance, drop the sensors at places close to the wall and which may have direct contact with water in case of a leak incident.

Step4:

Plug the power cable, valve cable, and sensor cables into the ports on the control module.
