For the second credit –
One of the following types of flow control device is fitted to each WC area/facility to ensure water is supplied only when needed
- A time controller i.e. an automatic time switch device to switch off the water supply after a predetermined interval
- A volume controller i.e. an automatic control device to turn off the water supply once the maximum pre- set volume is reached.
- A presence detector and controller i.e. an automatic device detecting occupancy or movement in an area to switch water on and turn it off when the presence is removed.
- A central control unit i.e. a dedicated computer- based control unit for an overall managed water control system, utilising some or all of the types of control elements listed above.
- Please note – The criteria are applicable to the cold water supply only and include cold taps, WCs and urinals. Any solution implemented to achieve compliance with this Issue should effectively mitigate the risk of hot-water scalding in showers, in the event that the cold water supply is shut off.
- A shut-off 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.
