Hi guys just wondering how much water you would use on a three bed house .Im just starting up and are using a trolley system its got five flo settings im using it on number one but seem to be using loads.The trolley holds 35L of water how many houses do you think i should be doing with that.I posted my first flyers yesterday only 150 and had five calls so far and did them today nerve racking lol..but they all seem to be pleased with my work.Do you lads leave the water running all the time your cleaning or turn of clean then rinse sorry to sound so dim but this is the first time iv ever used it and would be greatfull for any tips.ALB fuggy.....
