ABSTRACT:
A battery powered auxiliary sump pump is described which is a backup to the primary sump pump. The auxiliary sump pump provides an intermittent audible alarm and an intermittent visual alarm when the auxiliary sump pump is activated. Thus, the device provides an intermittent audible and visual alarm signal which is more perceptible to an observer than a continuous alarm.
