How it works
The basement drain with an integrated backwater valve reliably protects against wastewater flowing back from the sewer. Drainage points connected to the drain, such as showers, washbasins and washing machines, are also protected. The backwater valve can be locked manually during heavy rain or in the event of an extended absence.
