Big Dog Computer-controlled AC/DC Battery Backup Sump Pump System

The top-of-the-line, and most powerful, of Basement Watchdog three battery backup sump pump systems. Pumps 3500 GPH. at a 0 ft. lift, or 2200 GPH at a 10 ft. lift. (A 10 ft. lift is needed in most installations.) This pump fits next to the main AC pump and automatically begins pumping during a power outage, when the main pump fails, or when water flow exceeds the capacity of the main pump. Its state-of-the-art monitoring system sounds an alarm when maintenance is needed or a problem arises. A light on the display panel will indicate the cause of the alarm and the corrective action. This computer-controlled model runs the pump weekly and monitors the system continually. It has a powerful 20 amp charger, which will recharge the battery quickly, and if the power is on, it will run the pump with AC current, instead of the battery. It evaluates the battery and indicates the percent of battery charge.
