Stronger than the backwater: The Pumpfix S is the only basement
drain with backwater valve, which pumps against backwater.
It normally drains sewage free wastewater to the sewer by
gravity – even handles incoming flood water or flooding from a
burst water supply pipe. Yet it shows its true strength in case of
backwater: The pump then switches on automatically and pumps
the building’s wastewater into the flooded sewer. It is also ideally
suitable for draining outdoor basement stairs.
The Pumpfix S is available in two models: a compact version
with polymer grating, which is particularly suitable for renovation
projects, and a larger version with multiple inlet connections
and a tileable cover.
Installation in waterproof concrete
The KESSEL sealing kit for installation in waterproof concrete
ensures reliable protection against moisture damage. The
extension section with central flange and elastomeric water-
proofing membrane can also be used for deeper installation.
Additional inlet connections
In addition to the cover with integrated inlet several lateral inlets
can also be attached, for a shower, washing machine and wash-
basin. The Pumpfix S basement drain can therefore also be used
as central backwater protection.
