6.3.3 Drain connection
Rules for safe installation of the drain connection
Observe the following rules to prevent hazards caused by a faulty drain connection:
■
There must be no restriction or reduction in the cross-section of the drain pipe.
■
The slope of the drain pipe must equal min. 3.5% (2°).
■
If more than one appliance is connected to one drain pipe, this pipe must be large enough to allow
the wastewater to flow out unchecked.
■
The appliance must be connected to the drain using a NON-flexible pipe. A fixed connection is rec‐
ommended; alternatively an open funnel waste trap can be installed.

composition of the wastewater. These include:
■
DIN 1988 part 2 and part 4
