CAUTION!
In the case of longer pipe runs with only a minimum gradient, it is possible for water pockets with a siphoning
effect to develop due to thermal expansion of the plastic pipes between the mounting points:
• The pipe should be fixed to a rigid structure (e.g. profile rail, pipe etc.).
• Always make sure that pipe runs have a continuous gradient of at least 2 %.
