Connection to the drinking water main
When hooking up to the drinking water
main, a backflow preventer must be
installed between the water tap and the
hose. The design of the backflow
preventer must comply with the
applicable country-specific regulations.
If drinking water has passed through the
backflow preventer, it can no longer be
regarded as drinking water.
Follow the rules laid down by the local
water supply company to prevent water
flowing back from the high-pressure
cleaner into the drinking water main.
