The Vevor sump pump battery backup system is designed to keep your basement protected during power outages and primary pump failures. It includes a smart controller, DC sump pump, float switch, and 15V adapter for a complete backup solution. The system monitors water level, power status, battery status, and float switch signals around the clock, activating automatically when needed. A copper motor delivers up to 2000 GPH with a maximum lift of 16', while the IP68 waterproof pump and corrosion-resistant PP construction support long-term use in damp environments.
