Flood & Leak Alerts

Phyn Water Sensors are engineered to provide fast, early detection alerts when a leak starts or weather conditions push water into the home. The moment water touches the metal probes at the base of the Sensors, a notification is sent directly to your phone, the device starts flashing, and an audible alarm is triggered. Phyn Water Sensors are your first line of defense against water and environmental damage.
