Water Leak Detection System with Automatic Shut Off Valve, 2 Sensors and Sound Alarm, Briidea Leak Water Automatic Shutoff, Flood Stopping for Water Heaters, Laundry and More
  • FLOOD PREVENTION: Freezing and cracking of water pipes caused by low temperature in winter and aging of water pipes or other reasons can result in a water leakage, which may damage the wooden floor or water heaters may even spontaneously ignite in severe cases. Suitable for household appliances with lever ball valves, this automatic valve shut off system is designed to prevent water leakage from causing you huge losses.
  • WORKING PRINCIPLE: This water leak detection system has two ways of detection mechanisms by a floor water leak sensor and a pressure release pipe sensor. As long as any one of them detects a water leak, it will trigger an alarm and automatically shut off the valve to protect your home or business from damages caused by floods. Save your money on homeowners insurance!
  • PRODUCT FEATURES: The sensors are designed to be highly sensitive-- the floor water leak sensor will activate once it senses water, and the pressure release pipe sensor will only activate after one minute of continuous water leakage, which reduces the risk of false alarms; The controller is very easy to operate with three indicator lights. Enjoy the convenience and benefits our product brought to you!
  • EASY INSTALLATION: There are two simple installation methods and the required installation supplies are in package. The stainless steel clamp is suitable for various sizes of water pipes; No wiring required, simply install the device and place the water leak sensor on the floor. Just a few of minutes, no more water leakage worries at home.
  • LOUD ALARM: The alarm sound (higher than 90db) is loud enough to warn people in the house at once. With our user-friendly setting, you can also set the alarm to sound only 10 seconds if it is activated, in case you can't tolerate the sound.
