Hi All,
I also found that now I have removed the pipe from each section the will store inside each other

That was OK until one section flew out of the end

Then I realized that the Velcro straps could be stuck together to stick each section to the next one

I then realized I didn't need the Velcro straps

Just twist the tube round a couple of times, as Alex said.

The other thing is I don't have a stop valve on the pole or on the Backpack delivery hose. So I use the switch to turn the water on and off. At first I thought this would be a pain in the a***e. But ....no it isn't.
What I do is flick to 1st setting to wash the window then flick to 2nd setting to rince. The quickly 1,2,3, clicks and it's off.
Now this method is saving me quite a bit of water and is avoiding me having to fill up the Backpack as often. And, as I am not using the pressure switch or turning the flow down and straining the pump the battery should last longer. Mind you, on the other hand, I could wear out the switch which will mean a new PCB???
What do you think folks (Jeff?)
