Staufix backwater valve

The original solution for wastewater.

Staufix backwater valve for floor slab installation

You can't improve on an original. But we can. The new Staufix backwater valve is the result of decades of product development and optimisation. It is just as safe as the original Staufix, but now even more compact, allowing a simpler installation and more flexible mounting.

The Staufix backwater valve is available in two versions – for installation in an exposed drainage pipe and for floor slab installation, where you can choose between a black cover or tileable cover.

At KESSEL, we are also constantly putting our products to the test. In addition to product quality, the focus is also on functionality and simple installation. For example, we have made the well-known Staufix backwater valve even more compact and easy-to-install.

Staufix backwater valve installation situation

Installation situation

The Staufix and StaufixControl backwater valves can be installed either in an exposed drainage pipe or in the floor slab – convenient and tidy thanks to the installation kit with a vertically adjustable upper section. Even installation in waterproof concrete is possible by means of an extension piece with flange and an elastomer waterproofing membrane.

The one-handed closure allows convenient maintenance without tools.

Tool-free maintenance

With the one-handed closure, the cover is particularly easy to open and close ­– for convenient maintenance, with absolutely no tools required.
