Technical field

The present invention relates to a discharge system according to claim 1.

State of the art

Due to the state of the art, different flushing systems for toilets and urinals are known. In principle, a distinction must be made between pressure flushes, in which the flush water is brought to the toilet bowl or urinal under the pressure of the pipe, and gravity flushes, in which the flush water is brought to the toilet bowl or urinal due to the force of gravity.
