Preassembled for Easy Installation

When you buy a Basement Watchdog Big Combo CONNECT (Model CITS-50), most of the plumbing has been done for you. The primary AC sump pump and battery backup pump come preassembled—including check valves, elbows and pipe already measured and glued—making it fast and hassle-free for you to install the best protection in the industry.

The Basement Watchdog BWSP 24-7 Monitoring Controller
24/7 Monitoring

The controller for the backup pump on your Basement Watchdog Big Combo CONNECT (Model CITS-50) combined battery backup and sump pump system provides crucial, 24-hour-a-day monitoring of pump, power and battery conditions, ensuring your system is ready to protect. The easy-to-understand controller detects irregularities, sounds an alarm, and visually pinpoints problems and solutions on the front panel.

Big Dog pump protects automatically
Protects Automatically

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.

The Basement Watchdog Big Dog (CITS-50) has two dual float switches for 4x the protection
2 Dual Float Switches—4x the Protection

The Basement Watchdog Big Combo CONNECT (Model CITS-50) includes two sets of microreed 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 floats are good, four are better.

Pumping Power of The Basement Watchdog Big Combo CONNECT (CITS-50)
Pumping Power

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

automatic, multi-stage, 20-Amp smart charger
Automatic Smart Charger

The battery backup pump on The Basement Watchdog Big Combo CONNECT (Model CITS-50) is equipped with an automatic, multi-stage, 1.6-Amp charger that keeps the battery fully charged and ready to go. Plus, it’s compatible with our maintenance-free battery.

Product Specifications

General

Pump Category/Type

CITS-50 Combination

Other Model CITE-33 Combination

AC & DC Pumps: Duty Type

CITS-50 Continuous

CITE-33 Continuous

AC Pump: Motor Horsepower

CITS-50 1/2 HP

CITE-33 1/3 HP

What does AC Pump: Motor Horsepower mean?

A unit of power that indicates how much work a pump can perform when connected to a working wall outlet. The higher the horsepower, the more powerful the pump is, allowing it to move more fluid, overcome greater pressure, or lift fluid to higher elevations   

AC Pump: Motor Cooling

CITS-50 Water-Cooled

CITE-33 Water-Cooled

What does AC Pump: Motor Cooling mean?

How are pumps cooled? Most pumps are oil filled, using dielectric oil to draw heat from the motor and lubricate the bearings. That oil is in contact with the housing of the pump, which is cooled by the groundwater in the pit. Water-cooled motors have both more efficient motors and better bearings, which create less heat and no need for cooling oil. The motor is pressed directly against the housing, which is cooled by the groundwater in the pit. Note: A small amount (less than 1 oz.) of food-grade oil is in the bearings of a PSC motor for lubrication, not for cooling the pump.

AC Pump: Motor Type
