of the hose between the back-
fl ow preventer and the high
pressure washer must be at
least 10 metres to absorb pos-

eter ½ inch).
Operation by suction (for ex-
ample from a rainwater vessel)
is carried out without backfl ow
preventer. Recommended suc-
tion set: 126411387.
As soon as water has fl own
through the BA valve, this water
is not considered to be drinking
