Mounting conditions
The following requirements exist for the mounting of the drain / over-
flow:
n
The bathtub is installed.
n
The drainage line is installed all the way to the bathtub.
n
The underside of the bathtub is accessible.
Backflow situation: If a negative pressure situation should occur when
the bathtub is filled, there is a possibility that bath water may flow back
into the drinking water system.
To ensure that no bath water flows back into the drinking water system,
a pipe interrupter must be installed in the pipeline between the shut-off
fitting and the bathtub inlet.
The following schematic diagram shows what this should look like:
