The comparison illustrates the difference:
With Geberit SuperTube (illustration on left), the discharge capacity is 12 l/s. This technology facilitates a consistent discharge pipe with a pipe dimension of d110, meaning there is no need for a ventilation pipe. What's more, the horizontal pipelines can be laid to a length of up to six metres without a slope.
A conventional discharge pipe (illustration on right) achieves a discharge capacity of 12.4 l/s with pipe dimensions of d160 and an additional d90 ventilation pipe.
