Standard-compliant in nominal widths

Ø 50 or Ø 75.

Individual drainage points such as washbasins, showers or

washing machines can be very simply protected against backwater

with the Staufix Ø 50 or Staufix Ø 75 backwater valves.

The Staufix Ø 50 or Ø 75 can be installed in the pipe to protect

several drainage points. There are also additional variants of the

Staufix Ø 50 with siphon traps, with washing machine connections

or with inlet funnel for the emergency overflow of heating systems.

This ensures that individual drainage points are protected.

Standard-compliant

The small backwater valves Staufix Ø 50 and

Staufix Ø 75 are each equipped with two flaps and an

emergency closure – and the first standard-compliant

backwater double valves for wastewater without

sewage per EN 13564 Type 2.

Area of application

The backwater valves are versatile in use: They can

be installed as individual safeguards for washbasins,

showers or washing machines, as a central backwater

protection in horizontal drainage pipes or as an

emergency overflow for heating systems.

Tool-free maintenance

The maintenance and cleaning of the backwater

valves is particularly convenient and possible without

any tools whatsoever thanks to the quick-release

closure.
