This is an amazing device. From ease of setup to alert functionality to product support, it’s the total package.

Worked 2 days after installation. Saved my basement from flooding.

I had lamented for the last couple of years that there was no way of knowing the status of our sump pump, while we were away from home. Battery back up units just didn’t have the capacity to keep things dry. With the PumpAlarm I can know immediately when a problem begins and initiate a response before things get out of hand.
