GROHE Sense is a smart water sensor that is placed in the home wherever there is the risk of a leak, such as the basement, laundry room, bathroom or kitchen. It detects leaking water around-the-clock and alerts homeowners. GROHE Sense Guard goes one step further. It tracks water pressure and the flow of water in the main water line, and measures home water consumption. It automatically turns off the water supply when a pipe breaks or water usage exceeds a specific maximum set by the user.
