Water Heater Watchdog Water Sensor, Alarm, and Pump

All-In-One Overflow Protection Device for Water Heaters

The Water Heater Watchdog by Kevlyn Pumps is a unique system for fluid detection and notification that also has a pump that can move up to 340 GPH of water. Your equipment starts to leak into a pan. The device has a sensor that can detect the water. Once detected it will start the audible alarm and send a push notification to your mobile phone. If the leak continues, another notification will be sent when there is one inch of water detected. When the water reaches a predetermined height, the pump will start. If the silence button is pushed it will reset the alarm.
