2.2 Intended use
2.2.1 Areas of use
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.
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.
Viega recommends closing the emergency trap if operation, where no
wastewater is produced, is interrupted for a number of days.
