Drinking water connection
To prevent the intrusion of non-drinking water into the drinking water
pipelines, concealed pipe interrupters are installed between the mixer
tap and an inlet. The Viega concealed pipe interrupters can be used as
a safety mechanism, if the following points are ensured during installa-
tion:
n
The direction of flow runs from diagonally downward to vertically
downwards. Pipelines are not allowed to rise downstream from the
pipe interrupter.
n
The pipe interrupter must be installed at least 150 mm above the
highest possible non-drinking water level.
n
There must not be any shut-off downstream from the pipe inter-
rupter.
n
The pipe interrupter must not be involved in the pressure test with an
installed membrane, the membrane is destroyed during a pressure
test and the pipe interrupter cannot perform its function. If a pressure
test is required, the insert with the membrane must be exchanged for
a connecting piece, model 6161.83.
n
Pipe interrupters may only be used with compatible components.
