Stronger than the backwater: The Pumpfix S is the only basement drain with a backwater valve that pumps against backwater. It normally disposes of wastewater without sewage continuously via the free slope to the sewer – even in the event of a burst water pipe or flooding. Yet it shows its true strength in the event of backwater: The pump then switches on automatically and the Pumpfix S drains reliably, even against the backwater pressure. It is also ideally suited for draining outdoor basement stairs.
The Pumpfix S is available in two versions: a compact version with a polymer cover, which is particularly suitable for renovation projects, and a larger version with numerous connection options and a tileable surface.
In addition to the inlet option via the cover, several horizontal inlets can also be attached, for example, for a shower, washing machine and washbasin (Drilling open the drain body allows connections of up to DN 100 to be fitted, above the compression flange and in the upper section up to DN 70). The Pumpfix S basement drain can therefore also be used as central backwater protection.
