Basement Watchdog makes two kinds of systems: battery backup pumps that sit beside the primary pump you already have, and combination units that replace your primary pump and add a backup in one assembly. If your current primary pump is sound, look at the backup-only models (Emergency BWE, Special CONNECT BWSP, Big Dog CONNECT BWD12-120C). If the primary pump also needs replacing, a combination unit such as the CITE-33 covers both jobs.
This page uses Basement Watchdog’s product pages. Nobody flood-tested these pumps for it, and it doesn’t compare failure rates with other brands.
Which configuration fits
| Situation | What to look at | What still needs checking |
|---|---|---|
| Primary pump works; you want outage protection | Backup-only BWE, BWSP or BWD12-120C | Pit space for a second pump, battery and controller location, discharge tie-in |
| Primary pump also needs replacing | Combination unit such as CITE-33 | Whether the whole assembly fits the pit; capacity of each pump at your lift |
| You want phone alerts | A CONNECT model plus the optional Wi-Fi module | What still alerts you if the home’s internet goes down in the same outage |
Basement Watchdog’s backup pump range lists the BWE as its most economical backup, the BWSP as its best-selling one and the Big Dog CONNECT as its most powerful. All three use a dual float switch and a controller that monitors the pump, power and battery around the clock. A backup-only listing doesn’t include a new AC primary pump.
CITE-33: read the numbers at your lift
The CITE-33 combination unit pairs a 1/3 HP AC primary pump with a battery backup pump. The two pumps have very different capacities:
| Pump | Flow at 0 ft | Flow at 10 ft | Maximum head |
|---|---|---|---|
| AC primary (1/3 HP) | 3,720 GPH | 3,100 GPH | 22 ft |
| Battery backup | 2,000 GPH | 1,000 GPH | 15 ft |
At a 10-foot lift, the backup moves about a third of what the primary does. Size the plan from the backup’s flow at your actual vertical lift plus pipe losses, not from the zero-lift number on the box. If heavy rain already keeps your primary pump running constantly, the backup may not keep up during an outage.
Other published details for the CITE-33:
- Battery: sold separately. Basement Watchdog lists the BW-27AGM and says the system works with maintenance-free AGM or wet-cell batteries.
- Runtime: 80 hours on one battery, based on a 10 percent duty cycle. A pit that cycles more often drains the battery faster.
- Discharge: 1-1/2-inch NPT on the AC pump; 1-1/4-inch FNPT on the backup, with a 1-1/2-inch adapter.
- Switches: dual micro-reed float switches on each pump.
- Warranty: two-year limited, extendable to four years when you buy the battery and register.
Before you buy
Measure the pit diameter and depth, and check that both floats can move freely without touching the pit wall, the pipes or each other. Budget for the battery if it isn’t included, and decide where the controller and charger will mount, away from water. Test the system the way the manual says to, and replace the battery on the schedule it gives. If water has reached outlets or equipment, stay out of it and call an electrician or your utility rather than troubleshooting powered equipment.
Verdict
Basement Watchdog is a reasonable choice for adding outage protection to a sump system, as long as you pick the configuration that fills your real gap. Keep a sound primary pump and add a backup-only model, or replace both with a combination unit like the CITE-33. Either way, size the plan from the backup pump’s flow at your lift.
