    Intended use for backflow traps
    According to EN 12056‑4 and DIN 1986‑100 drainage points beneath the backflow level should be secured under certain circumstances by backflow traps according to EN 13564‑1 against backflow from the sewer.
    If there are unsecured drainage points below the backflow level, cellar flooding can lead to damage to property, contamination and the risk of disease. The deciding factor as to what is above or below the backflow level is normal water level in the odour trap.
    Drainage points above the backflow level are not in danger of backflow. Drainage equipment should only be below the backflow level when it is absolutely necessary.

    The requirements on the backflow prevention are described in the standards DIN EN 13564‑1 and DIN EN 1986‑3.
    Maintenance should be carried out twice a year, inspections once a month.
    All Viega backflow traps are quality-​controlled in acc. with DIN EN 13564.
    The choice of product is determined by the type of water, which flows through the backflow prevention in the direction of the sewer.

    One differentiates between:
    • Waste water free from faecal matter – e.g. from showers or washing machines (grey water). All Viega backflow traps are suitable for use in grey water.
    • Waste water containing faeces – e.g. from urinals and toilets (black water). Viega offers Grundfix Plus Control for use with black water.
