The Liberty Pro370-series simplex submersible sewage packages are one of the most advanced residential sewage packages on the market. The series pairs a premium Liberty sewage pump with a 21"x 30", 41 gallon basin and a QuickTree float system.
The key feature of the series is the QuickTree float system which allows for easy removal and exchange of the floats without disturbing the pump. The QuickTree kit features a stainless steel float tree, pre-mounted pump float, and an additional clamp for an alarm float. The QuickTree can simply hang from the holder underneath the access cover. Other features of the Pro370 series includes integral rubber seals permanently attached to the cover, unique integrated cord seal technology, integrally molded torque stops that secure the pump in proper position, integrally molded anti-flotation collar, and integrally molded handles for easy transportation and installation.
The basins are durable polyethylene with radial ribs for added strength. The larger size (40% more capacity than standard 18" x 30" basins) also decreases switch cycles, which allows for longer pump life. All packages listed below include the basin itself and a Liberty sewage pump that can handle up to 2" solids. Some models may include accessories such as the Night Eye Alarm. Each basin package is shipped with a clear, disposable construction cover that protects the system during masonry work and rough-in.
Another strength of the Pro370 series is that each unit is compatible with a variety of optional accessories, such as an access riser that allows the basin to be buried to maximum depth of 18" below grade.
