Well there's certainly a big difference between 10 mins washing time( Ilford) and 60 galls per hour. I have no idea what rate of flow the Ilford routine specifies but I doubt it to be a gallon a minute. 60 gallons per hour is an incredible use of water in time of diminishing resources. I checked my garden hose operating at a reasonable rate in the summer and that was less than a gallon a minute. I wonder how the water authorities in Australia would regard that kind of use in the drought conditions several APUGers there have mentioned.

In the UK we now have water meters. At this rate my water bill would probably outweigh my other materials cost! I had thought of giving FB a try but at 60 gallons an hour neither my wallet nor my conscience would stand it.
