SOLOLIFT2 domestic lifting station - toilet discharge and grey wastewater



SOLOLIFT2 is a unique range of compact lifting stations enableing a drain of any domestic sanitary appliance wherever needed, independent from the gravity drain system. The units collect and pump the wastewater through a thin pressure pipe (>23mm) to the next down pipe – up to 6m high or 100m distance.

An extra toilet or a complete bathroom in attic or basement must be no longer only a wish with SOLOLIFT2.

The range consists of 5 compact lifting station variants for disposal of domestic wastewater.

3 units, called WC-1, WC-3 and CWC-3, are designed to take wastewater from a toilet and further sanitary appliances.

2 units, called C-2 and D-2, are designed to take grey wastewater from several objects.

The numbers indicates how many additional inlet connections are possible.

SOLOLIFT2 is designed according to the needs of professionals – high reliability and easy, clean service in mind.

The units come ready to use with a plug and operate full automatic when water enters the tank.


Wherever the drain of a sanitary appliance is required but no gravity drain pipe is available or possible. The units with a WC connection are dedicated to installation in private homes only. Other units can be utilized also for commercial application.

WC-1, WC-3 and CWC-3 are designed to take the wastewater of up to 1 toilet, 1 washbasin, 1 shower and 1 bidet.
CWC-3 is the extra slim variant, designed to be integrated in front-wall installation.

C-3 and D-2 are designed to remove the (hot) wastewater from a bath, shower, washbasin, sink, washing machine and dishwasher.

Their compact measurement enables the integration in front-wall installation and floor units.
