Test and monitoring system for a sump pump installation operable from a remote location

An automated system for testing and monitoring a sump pump installation of the type having a liquid container, a motor driven pump which following activation operates until subsequently deactivated by a predetermined control effect to pump liquid from the container, and a pump switch circuit which supplies current to the pump motor to activate the pump upon sensing the liquid level in the container having risen to a first predetermined level, the system comprising:

• a liquid conduit connected to an external liquid source and including an electrically-actuated valve which when open flows liquid from the external source into the container;
• a test control module which when actuated opens the electrically-actuated valve to initiate a test cycle during which liquid flows into the container to cause the liquid level therein to rise to at least the first predetermined level, after which the motor driven pump is activated to pump liquid from the container and the test control module closes the valve to terminate the flow of liquid into the container, the pump continuing to operate until occurrence of the predetermined control effect;
• a communications circuit for receiving and verifying from an external originator a control signal addressed to the automated system, and for actuating the test control module to initiate the test cycle in response thereto;
• and
• wherein the test control module further includes an indicator circuit which indicates a successful test upon deactivation of the pump.

An automated system for testing and monitoring a sump pump installation of the type having a liquid container, a motor driven pump which following activation operates until subsequently deactivated by a predetermined control effect to pump liquid from the container, and a pump switch circuit which activates the pump by supplying operating current to the pump motor upon sensing the liquid level in the container having risen to a first predetermined level, the system comprising:

• a liquid conduit connected to an external liquid source and including an electrically-actuated valve which opens to flow liquid from the external source into the container in response to an applied valve control signal;
• a test control module which when actuated applies a valve control signal to the electrically-actuated valve to open the valve to initiate a test cycle during which liquid flows into the container to cause the liquid level therein to rise to at least the first predetermined level, after which the pump switch circuit supplies current to the pump motor to activate the pump to pump liquid from the container, and the test control module closes the valve to terminate the flow of liquid into the container, the pump switch circuit continuing to supply current to the pump motor causing the pump to continue to operate until occurrence of the predetermined control effect;
• a communications circuit for receiving and verifying from an external originator a control signal addressed to the automated system, and for actuating the test control module to initiate the test cycle in response thereto;
• wherein the test control module includes a current sensor circuit sensing current supplied to the pump motor by the pump switch circuit;
• and
• wherein the test control module further includes an indicator circuit which, in response to the current sensor sensing the termination of current flow to the pump motor, indicates the occurrence of a successful test.
