Operating mode
  1. Water leak detection
    The water leak detector emits an audible alarm and sends a closure signal to the Sedna valve.
  2. Water inlet closure
    As soon as it receives the signal from one of the water leak detectors, the valve closes the water inlet automatically.
  3. Sending alerts messages
    As soon as the leak is detected, you will receive an email or push notification notifying you about the source of the leak and the closure of the water inlet*.
*Requires a permanent Internet connection and the Neviweb app available on the App Store and Google Play.

Up to 20 water leak detectors can be controlled with a single Sinopé smart water valve (VA4220WF / VA4221WF).

It is also possible to operate the valve without an Internet connection. However, you will not receive any notification when a water leak is detected.

Features
Valve
  • Remote access and control of the main water supply through smartphone and tablet*
  • Automatic valve closure as soon as a water leak is detected by one of the detectors.
  • Compact design facilitating access to the product once installed
  • Possibility to back-up the device with lithium batteries (not included) for ongoing operation
  • The valve is equipped with a self-testing system to ensure proper operation at all times
  • Possibility to open and close the valve manually
  • Removable controller allowing the replacement of parts without any further modification to the plumbing
Detector
  • Audible alarm and email or push notification sent notifying of a water leak, a risk of frost, or when the batteries are low*
  • Ultra-precise sensors detecting a minimum water level of 0.4 mm (0.015 in.)
  • Compact sensors that slide easily under the sink, toilet, bathtub and near the water heater
  • Probe facilitating the installation of detectors in hard-to-reach locations
  • Detectors powered by two AAA batteries that last up to 10 years on supplied lithium batteries 
  • Detectors with gold-plated sensing electrodes to counter oxidation
*Requires a permanent Internet connection and the Neviweb app available on App Store and Google Play. Without an Internet connection, no notification of valve closure or leak detection can be sent.
