Examples of the 3 Outlet Types Available(See following pages for other variations of outlet)
Series 7 (max 12l/s capacity)
Series 7+ (max 25l/s capacity)
Series 5 (max 6l/s capacity)
Geberit Pluvia is the leading syphonic roof
drainage system used throughout the world.
Architects, Consultants and Contractors have
chosen the system for some of the most
prestigious and ground breaking building
designs due to the freedom and flexibility it
provides.
Pluvia uses the ingenious gravity induced
vacuum principle to create a syphonic action,
which allows the complete drainage of a roof
area with smaller diameter pipes than used in
a conventional gravity system.
Geberit Pluvia Advantages
■ No slope in pipework required
■ Less underground pipe
■ Less sitework
■ Fewer pipes and fittings
■ Reduced pipe dimensions
■ Less space required
■ Self cleaning action
■ Quick and easy fastening system
■ The only system to be fully BBA Accredited
CD-ROM available with
installation details of
various outlets and roof
configurations.

Pluvia Rail System
The Geberit Pluvia rail system was developed for
the installation of horizontal pipework.
Advantages of the rail system
■ Quick installation
■ Fewer ceiling fastening points
■ Controls thermal movement
■ No expansion because of rigid installation
■ No expansion sockets in the horizontal pipes
■ Simple prefabrication is possible
■ One fastening for anchor and sliding brackets
The expansion and contraction of the pipework is
prevented by the rail system, the properties of
HDPE allows rigid fixing.

Brackets, Anchor Points and Expansion
The following conditions are important to
ensure perfect and easy assembly of the
sleeve:
1. Chamfering the inserted pipe end to
approximate 15°
2. Check the scale on the outer surface of
the expansion socket for insertion depth.
3. Mark the correct insertion depth
on the pipe.
4. Lubricate the pipe end well with soft soap,
Silicone or Vaseline.
N.B. Do not use oil or grease which can
damage the rubber seal.

Geberit recommend that a maintenance programme is
always implemented on completion of the project. The
intervals between inspection will depend on the
location of the building. The maintenance programme
should include:-
Clearing of all outlets of any debris
or silt as shown in figure 1.
a Remove lid
b + c Remove function disc
d Rinse function disc with
water
e Wipe outlet with cloth
1 2 3
Check that no pipes connecting
to outlets are blocked with silt etc,
if blockages are found they can
be removed by using a water jet
through the outlet after removing
the top unit and function plate (a,
b & c in figure 1)
Ensure all outlets have gratings
and tops in place. `order spares
from Geberit if necessary.

Testing of System
On completion of a Geberit Pluvia System the integrity of
all joints must be tested using an air test as described in
BS EN 12056, which in general requires a 38 mm air test
for 3 minutes.
If the installation has been designed
using the Geberit software it is not
normally necessary to performance
test the installation. Third party
approval by the BBA included
verification that the software is a true
reflection of the actual flow
performance.
