Grundfix Plus Control meets the
requirements as type 3 backflow
trap with double backflow protection
The backflow trap is suitable for use in drain pipelines made of HT or
sewer pipe DN 100, 125 or 150. When using other pipes such as e. g.
clay pipes or cast-iron pipes, the relevant adapters for HT and sewer
pipes must be used.
EN 12056
many
EN 13564
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 sanitary equipment, drainage equipment and pipe materials.
Viega recommends closing the emergency trap if operation, where no
wastewater is produced, is interrupted for a number of days.

Maintenance

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