Doubly secure with two self-closing flaps: The Staufix SWA backwater valve for wastewater offers especially reliable protection against backwater. In the event of backwater arising, the outer flap closes securely with the second flap providing additional security. The system can also be locked with a manually actuated emergency closure. Staufix SWA is suitable for showers, washbasins and washing machines.
Staufix SWA 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. It can be retrofitted with the Staufix FKA and Pumpfix F conversion kits – even when already installed.

Application possibilities
Thanks to its two pendulum flaps, the backwater valve Staufix SWA for wastewater without sewage offers double the security in laundry rooms, guest bathrooms or in the case of a separate washbasin below the backwater level. The following examples show the situations in which the Staufix SWA can demonstrate its strengths:
Installation kit for the floor slab
The backwater valve is available for floor slab installation and can also be installed in waterproof concrete by using an extension piece with central flange and an elastomer waterproofing membrane. The integrated drainage function ensures that any surface water that arises, for example due to a pipe break, will be pumped into the sewer despite there being backwater.
Simple retrofitting
The Staufix SWA backwater valve can be retrofitted with the Staufix FKA and Pumpfix F conversion kits – even when already installed.
