Hello I've converted to WFP not that long ago and I need some advice about how I can reduce the amount of water I use to clean windows , I've got eight 25ltr tubs for my trolley system I know I could have a van mounted system but my budget is limited at the moment , I want to pick up the pace abit and earn more but I use about a tub and a half on an average three bedroom semi. I've got a digital flow controller on my trolley I've tryed to reduce the flow to about 15 - 20 but the water doesn't seem to jet out much at all , I normally have the flow at 40 and the water jets out nicely but I go through alot of water. One chap from the firm I bought it from said that I can expect to clean two houses with just one 25ltr tub , so I'd like someone if possible from North Shropshire to give me some advice on how I can improve my technique and manage my water better.
