The Basement Watchdog BWSP Battery Backup Sump Pump System is a submersible pump that automatically switches to battery power during AC power failures, ensuring your basement stays protected even when the power goes out. This system pumps water out of your sump pit quickly and reliably, preventing flooding and water damage when you need it most—whether you’re home or away.
Designed for homeowners who want peace of mind during power outages and storms, this battery backup system combines a high-capacity pump with intelligent monitoring and alert features. The dual float switch and micro reed switch technology provide redundant protection, while the fluid sensor monitors battery performance and alerts you before power drops, so you can service the system proactively.
