Acceptable solution when installing kitchen mixers with
Soft-pex with LK PE-X and PAL Universal pipes Pipe-in-
Pipe.
When penetrations for LK PE-X and PAL Universal pipes
Pipe-in-Pipe without a wall box are to connect to a kitchen
or washbasin mixer, for example, the angle at the transi-
tion between the LK PE-X – LK PAL pipe and the mixer's
connecting pipe must be fixed. This is preferably done
using a wall washer fitted with thread connection.
Replacement of pipes in conduits
A damaged LK Universal PE-X pipe (size 16x2.0
mm) can usually be replaced without causing
structural damage. Provided that installation has
been carried out according to the instructions and
that LK Fixing plates and LK Clip for Sleeve Pipe
have been used to the extent prescribed by the as-
sembly instructions.
LK recommends a maximum of 4 bends from
manifold to termination/tap location; up to 2 of
these may have a radius of less than 100 mm.

Soft-pex
LK PE-X and PAL Universal pipe
LK PAL Pipe-in-Pipe is generally regarded as not
replaceable; however it can be replaced if only 2
bends with a radius of 100 mm are to be installed.
Replacement of pipe in conduit using LK Exchange nipple.
LK Pipe extractor PE-X 16.
Use LK Exchange nipple, RSK 187 37 91 for 16
mm PE-X pipes, to secure the damaged pipe to
the new pipe. Screw LK Pipe extractor, RSK 188
07 73, into the other end of the pipe, then pull out
the damaged pipe and replace it with the new
pipe. Replacement of Pipe-in-Pipe PE-X dim.
20 to 32 mm normally requires a maximum of
2 bends of large radius. Note that Pipe-in-Pipe
PE-X of dim. 20 mm fixed with LK Angle Wall
box 20 mm cannot be replaced.
Extracting a damaged inner pipe is facilitated by
means of the following measures:
• Softening of the pipe by flushing through
with hot water or hot air.
• Lubrication between media carrier pipes and
empty pipes with a mineral oil solution or
similar lubricant which reduces the friction.
Note that the conduit/sleeve pipe must be blown
clean after the change of the pipe.
