Our take on the Sentry Basement Sentry 12-Volt 29-GPM Thermoplastic Battery-powered Sump Pump STBB100

The Basement Sentry STBB100 is a 12-volt battery backup sump pump system that installs alongside an existing 115V primary pump in the same sump basin. It runs on a deep-cycle battery and includes the pump, controller, alarm, battery charger, float switch and battery box. It is aimed at homeowners who want flood protection during power outages or primary pump failure, and it also adds pumping capacity in heavy water. Against rivals it is a full kit rather than a pump alone, but the battery is sold separately and the 29 GPM rating is modest next to higher-output backup systems.

Questions and answers

Does the STBB100 include a battery?
No. It works with a deep-cycle battery, which is sold separately. Sentry recommends its own Basement Sentry batteries.
Can it replace my main sump pump?
No. It is a backup that installs in the same basin as a 115V primary pump. It handles outages and float failures, not everyday primary duty.
What is included in the box?
The 12V pump, controller, alarm system, battery charger, float switch and battery box. The primary sump pump and battery are not included.
How much water can it move?
It is rated at 29 GPM. That is enough for backup duty in most basements but lower than high-output backup systems.
Will it tell me when it is running?
Yes. The controller includes an alarm that sounds when the backup pump activates, so you know the primary has failed or power is out.
What kind of battery does it need?
A deep-cycle battery. Check the battery's capacity, since runtime during an outage depends on it.
