A space-saving, ready-to-use lifting system for single-room wastewater disposal, capable of handling wastewater from toilets, showers, dishwashers, washing machines, and basement kitchens.

The Wilo-DrainLift MINI3 series lifting systems provide reliable domestic wastewater handling. They are the ideal choice when gravity drainage is not possible. Depending on the model size, up to three inlets can be connected to handle wastewater from washbasins, showers, bathtubs, washing machines, or dishwashers. The compact design allows for integration into any pre-wall installation. Additionally, the system ensures quiet and discreet drainage. Models designed for toilets feature a sewage pump equipped with a rotating cutter for reliable and safe waste processing.
