I could always manage to do a full day on 400 but only after changing to fan jets and using aquadaptor.
I know you'll disagree, but you use more water on a lower setting than a high one, and have more risk of spotting ( but that's another debate/thread )

100% agree with that.
I used to use setting 2 on my flow controller, and I used to easily use 350 litres a day and that's the all the water I had, so I had to trad downstairs and WFP upstairs.
Now I upgraded to a bigger van with a 650 tank and I can work all day doing tops and bottoms WFP with just using about 600 litres or under, I also run my pump pretty much flat out on maintenance cleans and not only am I so much faster than before but I'm using less water than I was previously. I always get much better results and a lot less spotting.
Higher flow is the way forward.
Higher and hot. Honestly i never use more than 350...surprised you guys dont blow holes in glass with pressure you must be working with
Don't forget the wire brush for scrubbing, I sometimes wonder what some of the guys on here are getting on the glass ?
Flat out flow to wash 4 weeks of dust of a window, its no wonder they don't mind working in the rain as the water splashing
off the glass would soak them anyway.
Wether you use 0.2 litres per minute or 2 litres per minute (like I do) a window still takes the same amount of water to be rinsed clean. So no excess water is used when I clean, just the amount that is needed.
I've worked like this since I got my new van in January and I can get through a lot more work now as I'm quicker, which in turn means I'm earning more.
Problems can arise when you try and use less water than is needed.
Ask yourself if you had an unlimited pure water supply would you still try and clean windows with as little water as possible?
