Claim:
1. An automated system for testing and monitoring a sump pump installation of the type having a liquid container, a motor driven pump which when powered discharges liquid from the container, and a switch circuit which supplies current to power the pump motor upon the liquid level in the container rising to a predetermined level, and removes current from the motor upon the liquid level in the container falling to a lower predetermined level, the test and monitoring system comprising: a liquid conduit including an electrically-actuated valve which admits liquid to the liquid container in response to a valve control signal; a test control module which when actuated supplies a valve control signal to initiate a test cycle having an elapsed time during which liquid is admitted to the container to cause the liquid level in the container to rise to at least the predetermined level, to test the pump discharging of liquid from the 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 processor circuit for recording the elapsed time of successive test cycles; wherein the test control module includes an indicator circuit which indicates in response to completion of the test cycle whether the pump discharges from the container a portion of the liquid.
