Reliable and durable. This is proven by our Staufix backwater valve. It is the ideal solution to provide protection for individual draining elements such as a shower, washbasin and washing machine which are located below the backwater level.
The Staufix is available as a type 1 and 2. Type 2 has two free-hanging backwater flaps that protect against the ingress of water from the sewer in the event of backwater. In addition, one of these flaps can be manually locked via an emergency closure. The backwater valves are available in two different versions – for installation in an exposed drainage pipe and for floor slab installation, where you can choose between a black cover or tileable cover.

Application possibilities
The Staufix 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.
