That is a factoid often repeated in the press.It confuses pressure with flow rate.In reality, water companies are obliged to supply water at at least 1 bar pressure. There are many other reasons why you may not be able to obtain a flow rate of 10 litres per minute: household pipe too narrow, stopcock not fully open, other people using water in the same building.Incidentally, 1 bar is pretty puny. It is only enough to push water up 10 metres. If you are in the top floor of a three-storey building, your water will be at a trickle!
