The Little Giant SPBS Series Battery Backup System from Franklin Electric allows contractors to provide homeowners with peace of mind that their basement is protected from flooding when the electricity goes out. It comes in four systems: two options that feature the full system including a primary sump pump, backup sump pump, controller, charger, and alarm, and two options providing everything except the primary sump pump. The full systems use Little Giant 6EC or 10EC sump pumps that deliver capacities from 53 to 67 gpm. The result is a system with high flow rates, quick charging time and hours of battery longevity. Adding the RS-12 switch provides hours of reliable pumping when the electricity goes out. The switch technology requires nothing mechanical to operate the pump, minimizing the opportunity for mechanical hang-ups. 260/824-2900; www.littlegiant.com.
