Staufix SWA backwater valve

The reliable solution for wastewater.

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.

Advantages

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.
