Abstract

A test and monitoring system for a sump pump installation of the type having a battery-powered sump pump which pumps liquid from a sump container when the liquid level in the container rises. A current probe operatively associated with the electrical circuit between the battery and the pump provides an output signal indicative of current flow to the motor. The system includes a control module which is periodically actuated to initiate a test cycle wherein a valve is actuated open to admit liquid into the pit. If the pump is operative, the pump pumps liquid from the container, causing the liquid level in the sump container to fall, and the control module in response to the output signal of the current probe to terminate the test cycle and indicate a successful test. If the sump pump is inoperative, the liquid level in the container continues to rise and the test cycle is terminated, the valve is closed and an unsuccessful test is indicated.
