A high-pressure washer must have a garden hose of at least 7.5 metres, and Aquastop cannot be used .
Single-phase high-pressure washers usually consume between 300-700 litres of water per hour.
A normal garden hose with normal pressure normally delivers much more than this.
The water consumption of various AVA models can be found in the table below:
As an example;
Fill a normal 10 litre bucket with water. How long does it take?
60 seconds provides enough water for the P80 machines.
A water hose/garden hose is usually ½” (12mm). A hose of this diameter provides plenty of water under normal conditions. If you have particularly poor pressure, the high-pressure washer will work well for a while, and then run out of water. By releasing the pistol grip and pressing it back in, you will again be able to flush for a while before you run out. If this happens so often that the machine is ineffective, you can use a bucket or other water vessel and pull water stright form that. Put the garden hose/a suction hose into the bucket, and use the self suction function on the high-pressure washer.
A thicker hose can provide a larger water reserve in itself, but does not change the capacity of the pipe network behind the hose, so eventually your machine may still run dry.
Our high-pressure washers must not have more than 7 bar inlet water pressure, and most homes with higher pressure than 6 bar have a reduction valve, partly because washing machines/dishwashers and similar appliances have a maximum limit of 6.4 bar.
