quantity control on the trigger gun, the overflow valve
opens and part of the water flows back to the suction

When the trigger on the high-pressure gun is release,
the pressure switch switches off the high-pressure
pump and the high-pressure jet stops.
The pump switches on again when the trigger is pulled.
