Hello

everyone
I have had a 10 year break from window cleaning, and have just started back up. I am completely new to WFP work, and have done my first day with the pole today ( well 5 hours this pm; carpet cleaning job this morning )
Thing is - I have cleaned 6 houses totalling £90, admittedly all first time cleans, so probably quite dirty; and used about 275-300 litres of water! This seems a bit excessive to my novice brain. I had the PSI set at 49 for first 3 jobs, then 45 for next 2, and 40 for the last. Is it me, or is that a hell of a lot of purified water for that amount of work? I did do frames all the way round, and sills, and turned off the on/off pressure valve every time not in use.
What do you guys in the know think please?
From Steven, with thanks :Dfor your help
