The Basement Watchdog Emergency battery backup sump pump system can be easily installed in either a normal sized or narrow sump pit and automatically begins pumping during power outages, when the main pump fails or when water flow exceeds the capacity of the main pump. Its unique 24 hour a day monitoring system sounds an alarm when maintenance is needed, or a problem arises. A display panel indicator light will identify the cause of the alarm and the proper corrective action. The dual float switch provides double the protection and will activate the backup pump when either float is raised.
