9.2.2 Status display permanent yellow
Yellow (Duration)

Minor permanent water withdrawal or a small leak was
detected over a long period of time.

Water withdrawal or leakage was detected during
system restart.
Fl accurately indicates a pressure drop in the installation.
A few drops per minute can be detected as an error.
In most cases, the cause is leaking, dripping water outlets.
Examination:

Were any small quantities of water removed over a longer period
of time with short interruptions?

Were there people present?

Are there several slow dripping taps?

Do the solenoid valves of dishwashers and washing machines
really close tight?

Can drops be found on the taps?

Carefully check all water outlets.

Look for traces of limescale, e.g. in the toilet.
There were no persons present. Dripping end users are not
detectable:
Micro leaks in the piping system are possible!
Test the pipeline system for leaks (see chapter 8.1.4 "Test
operation").
If the fault persists and no cause can be found, a specialist is
required.
