Resideo’s new Braukmann L5 Wi-Fi Water Leak Shutoff Valve connects to the main water supply and can automatically turn off the supply to the home if a water leak is detected. Designed with the professional in mind, the high-quality valve is easy to install, support and offers easy monitoring via the Resideo App, the company says. An included 5' cable sensor can be plugged into the L5 that detects water along its entire length. The L5 can also connect with future and existing Resideo Wi-Fi Water Leak & Freeze Detectors to expand the coverage. Connect up to 100 sensor cables and lay them through a basement or utility room to extend the sensor length up to 500'.
