∫ the system shall be drained completely and dried out by
blowing air through the system, then, if practicable, the
piping shall be sealed to prevent intrusion of water and
foreign matter.
When the system is connected to the permanent water
supply with all taps and valves installed all draw-off points
should be opened until clear water exits the system. This
will assist in the development of the protective internal film
within the pipe work and draw fresh disinfected water into
the system.
In large installations, the flushing should be performed
in sections. Multi-storey buildings should be flushed by
commencing on the uppermost floor and working down
storey by storey.
Water services used to supply drinking water shall be
protected against contamination during installation,
commissioning and repairs. If any water supply service is
exposed to foreign substances or contaminated supply, the
service shall be flushed, chlorinated and tested before being
placed in service.
After the water system is in operation, special care needs
to be given when modification, change in usage patterns
or where extensions are added to the systems. The entire
system needs to be checked so that all requirements of the
Standards and Plumbing Code of Australia are continually
being met.
HOW CAN COPPER TUBE HELP?
Copper tubing has been the primary material for
Australian and New Zealand plumbing for over 50 years.
Design information, including the governing standards, are
based around copper and copper pipe sizes.
Taking the extra care and consideration when designing,
installing, commissioning and operating a plumbing system
will improve the quality, performance and life of the system.
Of the utmost importance is the profound effect these
steps can have on the quality of water being conveyed in
a system.
MULTI-STOREY BUILDINGS SHOULD
BE FLUSHED BY COMMENCING IN THE
UPPERMOST FLOOR AND WORKING
DOWN STOREY BY STOREY.
