I have a v2 backpack with a flow control valve fitted to the microbore hose coming from the pump.
When on full flow the pressure switch stop's the pump when I turn the flow control valve off. When I use the variable speeds and turn the flow control valve off, the pumps still runs even though the floe has stopped.

Might be worth trying to turn the pressure switch screw undone by a full turn to make it more sensitive - see if this works.

One full turn and problem solved, many thanks Alex, PS easy to get too. Where is the pressure screw on the v3?
