Discharging the
backwashing water
ATTENTION
(See chapter on “Safety information and
dangers due to non-compliance”)
An adequately dimensioned wastewater
connection (e.g. floor drain) to DIN 1986
must be available for the backwashing wa-
ter. If there is no wastewater connection an
appropriately sized bucket can be used.
The dimensioning depends on the local cir-
cumstances (e.g. wastewater pipe gradient,
number of pipe bends, length of the waste-
water pipe, etc.). The dimensioning must at
least allow all the wastewater to be dis-
charged at the same time. If it is not possible
to provide a wastewater connection directly
beneath the Domestic Water station, the
flushing 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 en-
sured in accordance with EN 1717.
The following points must be noted if a buck-
et 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. Oth-
erwise it is possible for the bucket to
overflow. Therefore the bucket must be
adequately dimensioned and the back-
washing should be carried out quickly.
