Yellow (duration)

Leakage measurement indicates slight leakage.

Water withdrawal or leak was detected during system
restart.

Their overall system was not tight for several hours.
Fl indicates with high accuracy a pressure loss in the
installation. Few drops per minute can be detected.
In most cases, leaking, little dripping water outlets are the cause.
Testing:

Were any small amounts of water taken over a long period of
time with short interruptions?

Were there any persons present?

Are there multiple slow-dripping faucets, if applicable?

Do the solenoid valves of dishwashers and washing machines
really close tightly?

Do you find drips forming on the faucets?

Carefully check all water leakage points.

Look for traces of lime, e.g. in the toilet.
Persons were not present. Dripping end users are not detectable:
Micro leakage in the piping system is possible!
Test the piping system for leaks (see chapter 8.2 "Checking for
leaks").
For larger systems (if the installation allows this by means of shut-
off valves), temporarily disconnect individual strings, floors or
devices from the system to be measured.
