Abstract
A sump, ejector, or other pump monitor configured to monitor the amperage of electric current power supplied through the pump monitor to a pump and communicate one or more signals regarding the amperage or variations in amperage to a remote signal receiving device which indicate a predicted failure or actual failure of the pump. In various embodiments, the pump monitor operates with a remote pump failure warning system. The remote signal receiving device or remote pump failure warning system provides suitable warnings to one or more user access devices.
