Claim Text:
1. An automated system for testing and monitoring a sump pump installation of the type having a liquid container and a battery-powered motor-driven sump pump which when actuated by liquid rising to a first predetermined level in the liquid container discharges liquid from the liquid container, comprising: a liquid conduit including an electrically-actuated valve which admits fresh water into the liquid container when actuated by a valve control signal; a test control module which when actuated supplies a control signal to the valve to initiate a test cycle during which liquid is admitted into the liquid container, the liquid level in the liquid container rising to at least the first predetermined level, to test the pump discharging of liquid from the liquid container, said test control module then supplies a valve control signal to stop the admittance of liquid upon a predetermined event terminating the test cycle; a current probe in electrical communication with the battery and the sump pump motor to provide an output signal indicative of current flow to the motor; and wherein the test control module further includes an indicator circuit responsive to the output signal which indicates a successful test in response to cessation of current flow to the pump motor.
