4.2 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 ap-
propriately 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 filter, 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 DIN 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 Back-
wash protective filter 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.
