Zoeller's Aquanot Fit 508 is the contractor's choice for battery backup sump protection — a step up from consumer systems in both capacity and reliability. The 508 pumps at 1,800 GPH at 10 feet of head on battery power, significantly outperforming standard backup pumps during peak water intrusion. The integrated charger maintains the battery at full charge and provides real-time diagnostics including charge status, AC power status, and pump operation hours. The system is compatible with group 27 and group 31 AGM batteries for extended runtime. Zoeller backs it with a 3-year warranty and has been manufacturing sump equipment in Louisville, Kentucky since 1939. A premium choice for homeowners in high-water-table areas or basements with finished living space to protect.
