A test and monitoring system for a sump pump installation of the type having two electrically-powered pumps in a sump container wherein each, when actuated by rising liquid in the container, pump water from the container to a dispersal site. A test control module initiates a first test cycle in which the operation of the second pump is inhibited and fresh water is admitted into the container until the first pump, if functional, pumps liquid from the container. The test control module then initiates a second test cycle in which operation of the first pump is inhibited and fresh water is again admitted into the container until the second pump, if functional, pumps liquid from the container. A separate indication of a satisfactory of unsatisfactory test is given for each sump pump. |

1. An automated system for testing and monitoring a sump pump installation of the type having a liquid container, a first electrically driven sump pump which, when actuated by a rising liquid level in the container, pumps liquid from the container, and a second electrically driven sump pump which, when actuated by rising liquid level in the container, pumps liquid from the container, the test and monitoring system comprising:
a liquid conduit including an electrically-actuated valve which, in response to an applied actuation signal, admits fresh water into the container; a test control module having a first test cycle which inhibits operation of the second pump and applies an actuating signal to the valve to admit liquid into the container until the first pump, if functional, to pump liquid from the container, and having a second test cycle which inhibits operation of the first pump and applies an actuating signal to the valve to admit liquid into the container until the second pump, if functional, pumps liquid from the container; and wherein the test control module includes first and second indicator circuits which indicate for each pump whether the respective test cycles were successful or unsuccessful. |
