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. |
