Basement drain "Pumpfix S" with pump

Wastewater disposal even when water backs up

If wastewater (without sewage only) occurs when the backwater valve is closed, the pump automatically switches on from a certain level and disposes reliably of washwater into the sewer even against backwater pressure.

Use:

For safe protection from backwater and draining through floor drains below the backwater level that have to be used even during the backflow phase.

Application:

• Showers, sinks and washing machines
• Dripwater connections on safety valves and heating equipment
• Cellar steps up to max. 20 m²

Pre-condition:

• Free gradient to the sewage pipe
• Rooms with lower-priority use according to DIN 12056-4

Must not be used:

• For draining wastewater collected above the backwater level
• For rainwater, with the exception of cellar steps
