Stack sizing
Basic requirements for selecting Sovent dimensions
The dimensions of the individual connection pipes,
the combined waste stacks and the underground/
collector pipes must be selected as for conventional
drainage, in accordance with applicable national
standards and regulations.
The dimensions of the Sovent stack must be selected
according to the following formula:

Geberit Sovent -
installation
In general, the installation of a Geberit Sovent
system follows the same rules as the installation of a
conventional drainage system. It does, however, require
much less work since secondary ventilation is not
necessary. The installation of a Sovent fitting is similar
to the installation of an ordinary branch fitting.
The Sovent fitting has six connection possibilities.
The connections are capped off and can be used to suit
the optimum installation configuration. It is necessary to
have a Geberit welding machine (Universal or Media).
Installation Instructions
Prerequisites:
• Temperature of the welding plate 230°C.
• Ambient temperature -10°C to +40°C.
• The reference values for the time needed for the
butt welding process are known.
• Fix the Sovent fitting into the welding machine.
• Saw open the required connections.
• Use a machine to plane the opened connection
off smoothly.
• Clamp the corresponding pipe section of the
connection pipe.
• Heat both clamped parts.
• Press the parts together and let them cool.
• Remove the finished Sovent fitting from the
welding machine.
