Backwater valve

Drehfix

The compact drain for renovation.

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 odour

trap, sludge bucket, manually locked emergency closure and a

discharge rate 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 suitable for renovation projects.
