Sump pump system

USPTO Application #: 20070258827
Title: Sump pump system
Abstract: A programmed microcontroller based sump pump system includes multiple pumps that can be employed with one as a primary pump and one as a back-up, or can be employed in combination to increase the discharge rate. The microcontroller monitors the back-up battery condition, and computes and displays the battery life; monitors the system for clogs or vapor locks in the discharge piping; switches to an emergency periodic pumping mode of operation, when needed; and notifies the user by phone or e-mail of a system malfunction.
