Discharging the
backwashing water
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
For the backwashing water a wastewater
connection (for example a floor drainage) in
accordance with DIN 1986 must be in place.
If there is no wastewater connection an
appropriately sized bucket can be used.
The dimensioning depends on conditions on
site (e.g. wastewater pipe gradient, number
of pipe bends, length of the wastewater
pipe, etc.). The dimensioning must at least
allow all the wastewater to be discharged at
the same time. If it is not possible to provide
a wastewater connection directly beneath
the domestic water station station, the flush-
ing water can be fed several metres to the
next wastewater connection, either through
a hose or a pipe to be fitted to the flushing
water valve. This pipe must have the same
dimension as the flushing water valve.
In all options, a free discharge must be
ensured in accordance with EN 1717.
The following points must be noted if a
bucket is used for backwashing:
–
If the mains pressure is high, water can
splash out of the bucket. In this case,
damage to property close to the domes-
tic water station is possible.
–
When the bucket is half-filled the back-
washing process must be stopped.
Otherwise it is possible for the bucket to
overflow. Therefore the bucket must be
adequately dimensioned and the back-
washing should be carried out quickly.
