triple backflow protection (two automatic and one manual emergency shutoff)
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.
