The problem when talking about high and low flows is everybody has a different idea of what a high and low flow actually is,
I wouldn't consider myself a high flow user but there would be as much if not more water running off the sills when I clean as
in Vins Video.
I wonder when some on here talk about a high flow are they comparing it to what some would consider a dribble.
I would relate the flow to be whatever my flow controller says as in high flow is 40+ on the digital flow controller
Its only a number on a screen, there will be many things that will effect the flow, the only way is to measure the amount coming
out at the brush head while timing it.
You will find that even with a high flow your talking around 2lts per minute, even a shurflo pump flat out would be doing well
to hit 3lts per minute at the brush head.
