Backwater valves

Staufix FKA

The reliable solution for

wastewater with sewage.

Particularly reliable motor operation: In contrast to conventional

backwater valves, the Staufix FKA closes the backwater flap

with the help of a motor. This means that it is also suitable

for wastewater containing sewage – not only for showers,

washbasins and washing machines, but also for toilets.

Staufix FKA 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.

How it works

1 Backwater valve

Sealing gasket set

During normal operations, both flaps are open

so that all the wastewater can drain away fully.

In the event of backwater from the sewer, the flap

is closed and locked by a motor and then opened

again automatically afterwards.

Installation kit for the floor slab

The backwater valve is available for floor slab instal-

lation with a tileable cover and can also be installed

in waterproof concrete by using an extension piece

with central flange and an elastomer waterproofing

membrane.

The backwater valve has a plug-in, fully

wired, convenient control unit with SDS

self-diagnosis system.
