The PS-C33 Combination Backup and Primary Sump Pump System comes pre-assembled with check valves installed, weep holes drilled, completely plumbed and mounted on a platform for quick and easy installation. The energy efficient primary AC sump pump will provide 3,000 GPH (50 GPM) at a 10 ft. lift and its caged dual float (DFC1.5) will deliver years of dependable service. The backup sump pump will protect from power outages, primary AC pump failure, primary AC float failure and provide extra capacity if needed. Plus, when maintenance is needed or a problem arises, it sounds an alarm, pinpoints problems, provides solutions on the control panel, and (using one of the Pro Series CONNECT Modules) can alert remotely via, text, email or in app notification. The backup system delivers 2,400 GPH (40 GPM) of pumping capacity at a 10 foot lift and will pump intermittently for days on a single charge of the Pro Series battery.
