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.
