Geberit Drainage Systems
System installation
Rigid installation with anchor brackets
Anchor brackets for rigid fixings must be stronger than
possible expansion or contraction forces (P) of the Geberit
HDPE pipe (see table opposite).
Th
is table shows that in the low temperature range
(Column 2) the forces are greater than in the high
temperature range (Column 1).
Whilst Geberit manufactures Pluvia anchor brackets
for its system, it does not manufacture or supply drop
rods for connecting the brackets to the ceiling. These
must be sourced from a suitable supplier that can
verify they can withstand the forces shown in the
table above.
5.2.3 Rigid fixing
Principal:
Any variation in length must be prevented by embedded
fixed points (electrofusion couplings, branches, bends or
collar bushes) or by the provision of corresponding fixed
point structures.
Rigid fixing of the Geberit HDPE system can be achieved
by using a proprietary bracketry system (that may in
incorporate struts or very strong drop rods) or the Geberit
Pluvia rail system, as outlined below.
