Then, according to chapter 8.2 "Checking the tightness", measure
each section of the installation in order to get an indication of the
fault location and the faulty section by means of a simple exclusion
procedure.
Disconnect connected appliances, a central water heater, washing
machines and dishwashers or cisterns from the mains supply using
the respective shut-off cocks in order to also check the end devices
or fittings for leaks.
Do not attempt to force open or close stuck, calcified fittings!
The risk of destruction of the fitting including an
unintentional water leakage is very high!
Very rarely moved and old fittings can also cause small
leaks after closing and opening. This also necessarily check
after a time.
If the leak cannot be found, close all water taps.
Now actuate all the cisterns of the entire installation once in
succession.
Please wait 5 min and do not remove any water!
Close the KFR valve on the water meter (see also next page, Figure
10.2.2).
