4.2 Discharging the
backwashing water
ATTENTION
(see chapter "Safety
dangers due to non-compliance")
An adequately dimensioned wastewater
connection (e.g. floor drain) to DIN 1986
must be available for the backwashing
water. If there is no wastewater connection
an appropriately sized bucket can be used
(see fig. 4).
The dimensioning depends on the local
circumstances (e.g.
gradient, number of pipe bends, length of
the wastewater pipe, etc.). The dimen-
sioning must at least allow all the waste-
water to be discharged 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
ensured in accordance with DIN 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 filter 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 (see fig. 4) and
the backwashing should be carried out
quickly.
