How it Works

Your Kevlyn Pumps “OPD350” is a plumbing trade designed fluid detection and notification system with an integral pump with the capacity to move 340 gallons per hour.

When your customer’s water heater develops a leak, the OPD350 primary sensor will detect the leak. An audible alarm will sound and the app will send a push notification to their mobile device.

The pump will start when the water level in the reservoir closes the low voltage circuit.. The pump will stop and start depending on water inflow.

A notification will be sent every hour unless the test/silence button is push. This will reset the notification to restart (if needed) in 12 hours.
