2.2.3 Replacing a damaged tapping valve
CAUTION!
A hole must be drilled in accordance withÄ Chapter 3.4.3
‘Tapping the supply line’ on page 20 to make a tight con‐
nection. The tapping valve must not be positioned at the
location of an existing hole. When a Viega tapping valve is
replaced, the new tapping valve must not be placed in the
position of the previously dismounted tapping valve.
Failure to comply may cause a leak in the connection to
the supply line.

Product information
Fig. 2: Components tapping valve
1 Spindle
2 Tapping / valve casing
3 Outlet sleeve with clamping ring
4 Pipe clamp bottom piece
5 Pipe clamp top
Geopress tapping valves are made of high-quality plastic. They are
equipped with an outlet sleeve for Geopress K.
The fitting is pressed onto the supply line. A spring set in the bottom
part of the pipe clamp keeps the pressing force on the pipe at a con‐
stant level. The integrated cutter is connected to the actuating spindle.
The cutter is used for tapping and subsequently remains in the fitting.
The cutter holds the cut-out pipe wall plate securely. The sleeve in the
drill hole prevents the tapping valve from twisting on the supply line.
The model is equipped with an operation shut-off for the house service
connection. The spindle acts as a drilling rod during tapping, and after
commissioning as an actuating spindle for the shut-off.

Traceability code
Product information
2.3.5
The position of newly laid pipes and connection lines, including detailed
information about pipeline parts, must be documented and regularly
updated. The traceability code on the tapping valve allows every con‐
nector to be traced back and simplifies the documentation in as-com‐
pleted drawings.

3.1 Transport
3.2 Storage
Handling
Leave the fitting in the original box, in this way spare parts important for
mounting won't get lost.
Remove the protective foil during mounting, as described in the
mounting instructions Ä Chapter 3.4.1 ‘Pressing onto the supply line’
on page 16.
3.3 Assembly information
3.3.1 Mounting instructions
Pipes must be visually inspected for the following damage before instal‐
lation:
n Ovalities: threshold values must not be exceeded, see Ä ‘Regula‐
tions from section: Notes on mounting’ on page 6.
This is valid for coiled bundles as well as rods.
n Dents
n Cracks
n Grooves (maximum depth 10 % of nominal wall thickness)
Only process the sections of the pipes, which do not exhibit these fea‐
tures.
Check scope of delivery
The design of the tapping valve for d 63 is different from
the other pipe sizes. The pressing takes place on the
opposite side of the outlet sleeve.

The following components must be included:
n Tapping valve
n clamping ring
n Locking pin for clamping ring and a replacement pin
n Fixing bolts for tapping valve

3.3.2 Space requirements and intervals
Adequate space is a prerequisite for mounting. Only carry out the
pressing when the hinged adapter jaw (model 2296.2 or 0796.2, Z2) or
Geopress hand press tool is placed exactly in the seat of the tapping
valve.

3.4 Assembly
3.4.1 Pressing onto the supply line
When replacing a faulty tapping valve, observe the instruction in
Ä
Chapter 2.2.3 ‘Replacing a damaged tapping valve’ on page 7.
Requirements:
n The supply line has operating pressure.
n The pipeline trench has been made properly.
n The main shut off valve for the supply line is accessible.
n The tapping point is 5 x DN, however at least 0.5 m from pipe con‐
nections or other pipe fittings.
n Information about the supply line to be tapped are available:
n General manufacturer's information
n Experience from previous mountings
n All components are operational.
n The required components of the tapping valve / connecting pieces
are the correct sizes.
n Pipes with protective coating have been stripped.
n The tapping point is free of grooves, damage and ovalities.
n All of the required tools are ready for use.
Handling
Pressing with a battery-powered press machine is
described in the following. Alternatively, the Geopress
hand press tool can be used.
▶ Prepare and clean the tapping point at the supply line. The surface
around the mounting point must be clean, undamaged and free from
grease.

Handling
▶ Remove the protective foil from the inlet of the tapping valve.
▶ Check the seal for damage, contamination and correct positioning.
▶ Position the tapping valve at the prepared point on the supply pipe.
▶ Push the bottom part of the pipe clamp into the first notch until it
snaps into place.
▶ Alignment: Turn the marking on the tapping valve centrally to the

3.4.5 Use
Telescopic stem extension
Handling
The stem extensions are equipped with a sleeve pipe bell suitable for
Geopress tapping valves. This prevents dirt from entering the sleeve
pipe and the concrete seat of the tapping valve. The stem extensions
are continuously adjustable and are self-supporting in any position.
Delivery sizes / Setting ranges [m]
n 0.70–1.00
n 1.00–1.50
n 1.25–1.80
n 1.50–2.00
If the tapping valve is operated with another support, it is possible to
prevent dirt entering the sleeve pipe via the scraper ring adapted to the
Geopress tapping valve (model 9696.2).

3.4.6 Leakage test
3.5 Disposal
Handling
Perform leakage test before drilling.
If performing a dry leakage test or a test with water before the tapping
process, the maximum test pressure of 700 kPa (7 bar) must not be
exceeded. This is a preliminary test to confirm that the tapping band
seals to the surface of the mains pipe. The tapping band is only rated to
the maximum operating pressure once the mains pipe has been tapped.
Carry out the test on a house service connection that is finished but not
yet covered. The result of the leakage test must be documented as
proof of the safety of the pipeline.
If a leak is found in a tapping valve during a leakage test, a new one
should be installed.
Separate the product and packaging materials (e. g. paper, metal,
plastic or non-ferrous metals) and dispose of in accordance with valid
national legal requirements.
