Our verdict
Pick the Wayne ESP25n for more flow at lift (28 GPM at 10 ft) and a cast iron build. Pick the Basement Watchdog BWE for its dual float switch and a control panel that monitors the pump, power and battery.
The central trade-off
Flow at 10 ft. 25 GPM for the BWE and 28 GPM for the ESP25n, per the makers.
Switching. The BWE's dual float gives a second chance to start.
Battery. Neither includes a battery; the BWE takes AGM or wet-cell.
