Our verdict

A preassembled primary and backup combo that most buyers install without a plumber, though its bundle of cords and floats can be a tight fit through a sump basin lid.

Overview

The Basement Watchdog CITS-50 is a preassembled and preplumbed combo system pairing a primary sump pump with a battery backup pump and a monitoring controller, built around a copper wound PSC motor.

A WiFi connect module, also sold separately, enables text, email, and push alerts through the Basement Watchdog app.

Preassembled primary and battery backup combo with check valves built in
Copper wound PSC motor rated 1/2 HP
24 hour monitoring with alarm and warning light
Compatible with AGM and wet cell backup batteries

Who it's for

Fits homeowners who want a primary pump and a battery backup pre wired together rather than sourced and plumbed separately. Less suited to anyone with a sump lid where floats have to route through a narrow opening, since a couple of buyers found that awkward.

Pros and cons

Pros

Ships preassembled and preplumbed with check valves already installed
Backup pump and battery keep the basement dry if the primary fails
Runs quietly according to multiple buyers
WiFi module option adds remote alerts through the app

Cons

Cords for the backup controller and primary float are not disconnectable, so fishing them through a sump lid means unbolting the floats
Battery and WiFi connect module are sold separately
One buyer had the main pump fail within 3 months from a float assembly issue

Performance notes

The primary pump's copper wound PSC motor is rated for efficiency and long service life, moving 73 GPM at 0 feet of lift and 59 GPM at 10 feet. The backup pump and controller run continuously in the background, monitoring pump, power, and battery status, and will sound an alarm and light a warning if the primary fails, at which point the backup pump takes over on battery power.
