Flow control on cold water supply

AΒ shut-offΒ on the cold water supply to the whole WC facility provides a simple and effective way of reducing potential water loss.
Taps which contain built in shut-off valves will not prevent any water leaks from the supply to the tap and so do not fulfil this intent.

The intent of the flow control criteria is to prevent minor water leaks occurring within the pipework of WC facilities.
