Liberty 442-25A-EYE: High-Output Wi-Fi Backup Pump System
Ensure your basement has maximum protection against flooding with the Liberty Pumps 442-25A-EYE Series High-output System. This is not a standard backup; it's a professional-grade, high-endurance solution designed for ultimate peace of mind. It pairs a high-flow 12V DC pump with a heavy-duty, fan-cooled 25A charger and a dual-battery box, providing significantly longer run times than single-battery systems.
The "EYE" in the name means it's equipped with Liberty's powerful NightEye Wi-Fi technology. This system connects to your home's Wi-Fi and sends instant, free alerts (text, email, or push notifications) to your phone for high water, power loss, or low battery conditions. You’ll know the status of your sump pit from anywhere in the world.
The microprocessor-controlled 25A charger is a workhorse, efficiently managing and charging two Group 27 or 31 batteries (sold separately). In extreme situations, the charger is powerful enough to run the DC pump as a continuous power supply.
