Uncontrolled water leaks cause immense amounts of damage every year. An effective protection is the installation or retrofitting of a safety fitting. The protectliQ safety fitting monitors the installation site with a wired sensor. It uses water sensors to detect imminent damage and shuts off the water pipe. In order to monitor an additional room, a second, wired water sensor can be connected. The easily installed safety device is used as a line fitting. The protectliQ is suitable for installation next to the pureliQ filter series, or the other filters of the Grünbeck product portfolio. Battery operation ensures reliable monitoring, even in the event of a power failure.
