Basement Watchdog Combo systems (Big Combo CONNECT CITS-50, Combo CITE-33): quick sheet

Covers: Factory-assembled primary + 12 V battery backup sump systems made by Glentronics under the Basement Watchdog name: Big Combo CONNECT CITS-50 (1/2 HP cast iron primary, BWSP-A 'Special CONNECT' backup controller with remote terminal and USB port) and Combo CITE-33 (1/3 HP cast iron primary, simpler backup controller). Both use a caged dual-float switch with a blue piggyback 'Dual Float Controller' on the primary and a dual float on the backup. Current manuals are dated 2025; older units sold under the same names may have different controllers, so match the controller model on its label (for example BWSP-A) to the manual. Model and serial labels: on the back of the black backup control unit, on the blue piggyback controller, and on the primary pump nameplate. Battery is sold separately (Basement Watchdog recommends its BW-27AGM). Search terms: Basement Watchdog Big Combo, CITS-50, CITE-33, Watchdog combo beeping, Watchdog battery light, Watchdog fuse light, Basement Watchdog reset button.

A one-piece pit assembly: an AC cast iron primary pump and a smaller DC backup pump share a wye fitting that ties into one 1-1/2 in. discharge, each with its own built-in check valve. The primary runs from the wall through a blue piggyback controller fed by a caged dual float. The backup runs from a deep-cycle battery through a black control unit that sits on the battery box, charges the battery, watches power, battery and pump, and sounds an alarm with a lit panel light that names the problem. On CITS-50 the controller also exercises the backup pump weekly and has dry-contact and USB (Wi-Fi module) outputs. Most service calls are an alarm that won't stop, a backup pump that ran because the primary failed, or a dead battery.
