With the Basement Watchdog Big Combo CONNECT (Model CITS-50) on guard, you’ll have confidence knowing your basement is protected. The control box automatically monitors the system, and should your power go out, the battery backup sump pump will take over to keep your basement dry.

Two Dual Float Switches—Four Times the Protection

The Basement Watchdog Big Combo CONNECT (Model CITS-50) includes two sets of micro-reed Dual Float Switches. We introduced this technology, proven reliable in other uses for over 50 years, to the pump industry and improved it by including two floats on each pump. Simply stated: if two is good, four is better.

30+ Years Protecting Basements

The Basement Watchdog has been protecting homes for over 30 years and continues to be a market leader. We build the most dependable, user-friendly pumps in the industry using intelligent design, premium components, and quality manufacturing practices that include thoroughly testing every single unit.

Pumping Power

The Basement Watchdog Big Combo CONNECT (Model CITS-50), our most popular option, moves an impressive 4,400 GPH at 0’ height (3,540 GPH at 10’ height) from the primary AC sump pump, and 2,600 GPH at 0’ height (1,850 GPH at 10’ height) from the battery backup sump pump. Plus, both the primary and backup can run simultaneously, providing extra capacity if needed.

Automatic Charging

The Basement Watchdog Big Combo CONNECT (Model CITS-50) is equipped with an automatic, multi-stage, 1.6amp charger that keeps the battery fully charged and ready to go. Plus, it’s compatible with our wet-cell and maintenance-free batteries. This model can handle two of our batteries, connected in parallel, to double your runtime.

The Basement Watchdog Big Combo CONNECT (Model CITS-50) can link to The Basement Watchdog Wi-Fi Module (Model BW-WiFi) or a home security system, allowing for real-time alerts via text, email, through our app, or from your home security provider.
