2.2.1 Areas of use
Correct place of installation of the
backflow trap
Securing of drainage points

Securing of drainage points
beneath the backflow level
Requirements in backflow traps
type 3
The backflow trap is suitable for faecal matter free, typical household
wastewater up to a temperature of 95 °C with pH values ≥ 4 or ≤ 10.
Use in industrial areas or in pipelines, which transport aggressive liquids
is not permitted. This includes cleaning agents, which can damage sani‐
tary equipment, drainage equipment and pipe materials.
EN 12056
DIN EN 12056-4
DIN 1986-100
EN 13564
Viega recommends closing the emergency trap if operation, where no
wastewater is produced, is interrupted for a number of days.

Product information
1 Street / backflow level
2 Area safe from backflow
3 Backflow level
4 Area at risk of backflow
5 Backflow trap
The connection of the upper floor to the underground pipe must be
made between the backflow trap and sewer within the building – only
then is it possible to ensure that the wastewater system can function
faultlessly. To ensure that drainage is guaranteed, backflow traps may
not be employed as the central safeguard for a building with drainage
equipment installed above the backflow level – in the event of backflow,
it would lead to flooding in the building due to wastewater being unable
to drain away.
See Ä „Regulations from section: Place of installation and installation
conditions“ on page 6
2.2.3
Maintenance
Maintenance must be carried out twice a year to ensure safe operation.
