Criteria for: Efficient Taps, Automatic shut off taps
Automatic shut off taps
This sub-category includes only push action operated taps with or without a spray attachment.
Applicants must show evidence of the product’s compliance with the sections of the Water Supply (Water Fittings) Regulations 1999 listed in Annex 1 below.
(Note: Compliance with the regulations may be demonstrated by WRAS* approval (or other independent test laboratory accredited to ISO 17025). Alternatively companies accredited to ISO 9001 may provide a declaration of conformity with the regulations.
All automatic shut-off taps must also meet the following criteria:
Hydraulic Characteristics:
When tested using the method and apparatus described in section 11 of BS EN 816:1997, but using dynamic pressures at the inlet to the tap at up to and including 5 bar +/- 0.2 bar pressure, the measured flowrate shall not exceed 6 litres/minute and the duration of flow shall not exceed 20 seconds.
- If a flow regulator is required to be fitted to the automatic shut off tap to limit the flowrate to 6 litres/minute at 5 bar pressure*, the tap and the flow regulator must be sold as one product.
- Where the tap is supplied with a flow straightner fitting, the two components must be sold as one product.
Manufacturers should apply to Defra with evidence that their products meet these criteria in order to appear on the Water Technology List.
