The powerful Big Combo CONNECT pairs a primary and backup pump in one compact system that is pre-assembled so it's easy to install. The primary pump expels 4400 GPH @ 0 feet lift (3540 GPH @ 10 foot lift), and the backup pump handles 2600 GPH @ 0 feet (1850 @ 10 foot lift). The unit's controller monitors the pump, power and battery conditions 24/7, ensuring your sump system is ready to protect. The system's two sets of dual float switches make sure both pumps turn on when needed. With the Big Combo on guard, the control box monitors the system and activates the backup pump if the power goes out or the AC pump fails, keeping your basement dry. The system is compatible with the Basement Watchdog Wi-Fi Module, which provides real-time alerts via text, email or through the app to let you know the status of your sump system whether you are at home or on the go.
