The Drehfix is a basement drain with integrated, removable backwater valve (Type 5). In addition, it protects connected discharge points such as washbasins, showers or washing machines against wastewater from the sewer. With an odour trap, sludge bucket, manually locked emergency closure and a drainage capacity of 1.8 l/s, it can be used flexibly and is so compact that it fits in the recesses of old cast iron drains. It is therefore ideally suited for renovation projects.
Integrated backwater valve
The basement drain with an integrated backwater valve reliably protects against wastewater flowing back from the sewer. The backwater valves can be locked manually during heavy rain or in the event of an extended absence. Thanks to the practical one-handed closure, the drain can be opened quickly and conveniently maintained without tools.
