Backwater pumping station

Pumpfix F

The unique backwater solution.

More than a backwater valve: Pumpfix F is the only backwater

valve that pumps against backwater. In normal operation, the

backwater pumping station continuously disposes of the waste-

water via the slope to the main sewer, making it energy-neutral.

In the event of backwater, the backwater

flap closes automatically

to protect the building from flooding and any wastewater from

the building is pumped into the flooded sewer via the integrated

sewage. The integrated cutting system shreds solids meaning

the Pumpfix F can be used with wastewater containing sewage.

It can also drain basement staircases up to 5 m2.

Pumpfix F is available in two variants – for installation in an

exposed drainage pipe and for floor slab installation, where you

can choose between a black cover or tileable cover.

Application

For flats under the backwater level with no access to a toilet

above backwater level.

How it works

Pumpfix F is the only backwater valve with hybrid

function: In normal operation it uses the natural slope

to the sewage pipe. In the event of backwater from

the sewage pipe, the pump is automatically switched

on in order to reliably pump the building’s wastewater

into the flooded sewer.

the requirement for costly roof
