When using the Geberit Pluvia rail system (see section
5.2.4) the fixing to the structure is at 2.5m centres. The
fixing between the rail and the pipe is as shown on the
above table for horizontal bracketry fixing.

The main purpose of guide brackets is to support the
pipe and allow the axial movement caused by the effects
of expansion and contraction.
For all fixations of Geberit HDPE pipes Ø 40 - 315mm
except for anchor brackets.

System installation
Geberit HDPE drainage system pipes and fittings are
used for all above ground drainage applications, soil
and waste, siphonic rainwater, gravity rainwater and
chemical waste systems. They may also be used for
underground drainage applications, provided the pipe
work is under the footprint of the building (maximum of
1 metre outside the building outer walls).
5.1
Spacing for bracketry
Geberit HDPE pipes are to be fixed with anchor brackets
and guide brackets. The distance between anchor
bracket
s
is
a
maximum of 6 metres or whenever stability
is required in the system.
