Flushing and disinfection of drinking water installations
Note:
The DVGW work sheet W 557 Cleaning and Disinfection of
Drinking Water Installations and ZVSHK (German Central Association
Plumbing, Heating, Air Conditioning) instruction sheet "Flushing,
disinfection and commissioning of drinking water installations" include
all the key requirements for practical application.
1 | General
If a drinking water installation is not operated immediately after filling
and flushing or disinfection, in accordance with DIN EN 806-4 6.2.1, the
water must be replaced at regular intervals and at the latest after 7 days
The prerequisites for flushing are installation and preparation as per
chapter D, compliance with the instructions of the manufacturers of the
parts used in the installation as well as observance of the local
conditions and regulations.
2 | Flushing of pipes with a water/air mix
1.
Close all withdrawal points.
2.
Completely open all shut-off fittings (e.g., maintenance fittings) in
the piping section to be flushed.
3.
Insert the flushing compressor power plug and press the program
button "water/air mix" on the flushing compressor control unit (the
compressor aggregate fills the compressed air vessel).
4.
Slowly open the on-site water inlet shut-off fitting. The flushing air
pressure automatically adjusts to the water pressure (the
compressed air is fed into the water stream in a volume-controlled
and pulsatile manner as soon as there is a flow as a result of
opening the withdrawal points).
5.
Deaerate the entire drinking water installation via, for example, the
withdrawal points and check that the components installed (e.g.,
bypasses ...) are leakproof.
6.
Open the withdrawal points of the flushing section in accordance
with the flushing order, fig. D-16 pos.
