    My control goes 0 to 99. Max flow is 5 litres per minute at 100psi. I generally have it set to 20. So about 1 litre per minute. Sometimes goes up to 40 if required.

    [SIZE=medium]That’s a very low water flow rate Hotwash, you must be using a slow brush with many more brush strokes. It would take 15 seconds just to get 250ml of water onto the glass, which is about the same as cup full.[/SIZE]

    [SIZE=medium]If your using the extreme brushes & light poles, the weight saving is pointless if you spend all day taking longer to clean. This is just common sense, spend 1 hour doing a job with lighter equipment or spend 30 minutes with better but slightly heavier equipment - for the sake of a few extra grams in weight, which window cleaner has used more energy and is going to be more tired at the end of the job?[/SIZE]

    [SIZE=medium]Double your water flow rate, get a faster brush and the same amount of water can still be used in half the time, but with a more efficient brush you will end up using less water to remove the dirt. [/SIZE]

    [SIZE=medium]Personally I use a higher flow rate than this; I would recommend at least 2.2 litres of water a minute as a minimum when using Tecbuk brushes. [/SIZE]

    [SIZE=medium]Switch your wfp system on Gmeister, and then catch the water coming out from the brush into a bucket. Do this for 1 minute, stop the water then measure how much water you have collected in a jug with measuring scale on.[/SIZE]

    [SIZE=medium]Give or take 10% and you have a good idea to how much the water flow rate is when working.[/SIZE]
