slab which will be protected against
groundwater or earth moisture – sealing gas-
ket set 83023 must be used (accessory). If
the concrete slab will be equipped with a
membrane or sheet – this sheet is to be
connected to the Staufix SWA body with the
counter flange supplied with the 83023. In
the case that a water proof concrete is being
used then the heavy duty Kautschuk seal (in-
cluded with the 83023) is inserted and then
fixed tight with the counter flange. Please in-
stall the Kautschuk flange properly so that

access to the backwater valve for service or repair. It may be required that the upper section
is shortened to meet on-site installation heights / requirements.
