dirty water back into the drinking water main.
This can pollute the drinking water.

washer directly to the drinking water
main.
► Observe the regulations of the water supply
company. If required, use proper system
separation (e.g. backflow preventer) when
connecting to the drinking water system.
■ Dirty or sandy water can damage components
of the pressure washer.
► Use clean water.
► If using dirty or sandy water: Use a water fil‐
ter with the pressure washer.
■ If the water supply to the pressure washer is
insufficient, components of the pressure
washer may be damaged.
