Staufix SWA - Backwater Valve

The basis for your security

The twin flap backwater valve Staufix SWA can be used as central backwater protection according to EN 13564 type 2. It is suitable for showers, sinks and washing machines that are located in the basement. Cellar steps up to 5 m² can also be drained via the backwater valve, if penetration of rainwater into the building during the backwater phase is prevented by a thresher or similar solutions.

Normally, the waste water flows from the building through the backwater valve into the sewer. Backwater from the sewer is prevented from entering the building by the backwater flaps. One flap can be also locked using a manual emergency closure during a backwater incident or longer periods of absence. The second flap serves additional safety.

The backwater valve Staufix SWA is available as an installation kit for the concrete slab and is especially well suited for new buildings. The version for exposed drainage pipes is a good option for renovation projects and can be fitted quickly and easily.
