The backflow sensor reacts at accumulation heights of
100 mm, measured from the upper edge of the base pipe‐
line.
Therefore, when planning, the installation heights of the
existing floor drains, out of which water could flow in the
case of backflow, must be taken into account.
If a backflow trap is retro-fitted in a base pipeline, the
height difference of 30 mm between connection pipe and
sleeve must be taken into account.
