Standing for The Water Regulations Advisory Scheme, this standard is all about protecting public health by preventing contamination of public water supplies. Any water fitting which carries or receives water from the public mains water supply in the UK must comply with the Water Supply (Water Fittings) Regulations or Scottish Byelaws. These require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard.’

This approval is the best way of demonstrating that a product has undergone rigorous testing and is a great indication of the quality of a product.
