All-In-One Overflow Protection Device for Water Heaters

The Kevlyn Pumps “OPD350” 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 OPD350 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, and another notification will be sent. A notification will be sent every hour unless the silence button is activated. If the silence button is pushed it will reset the alarm and notifications to start again in 12 hours.
