The premium backwater valve for wastewater without sewage is equipped with two mechanical flaps which close automatically in the event of backwater. One flap serves at the same time as an emergency closure to be closed by hand. Thanks to the modular KESSEL system, existing systems can easily be converted to a Staufix FKA premium backwater valve or a Pumpfix F backwater pumping station.
