Meet Flood Buzz: the lean, mean, water leak-detecting machine trusted by homeowners for over 10 years and named by Plumber Magainze as "America's most cost effective water leak alarm". Flood Buzz alarms are small but powerful devices that emit loud alarms as soon as water touches them. There are no moving parts, no extra components to break, nothing to install, and they are fully reusable with internal batteries that last for several years.
