UK law requires that water devices or water products will comply with the requirements of the current Water Supply (Water Quality) Regulations and Water Supply (Water Fittings) Regulations. In the case of water device design or water product design, the Regulations lay down certain requirements pertaining to the design and installation of water fittings for use in water systems within properties in the UK. The Water Quality Regulations relate to the materials and substances that may be present within the water supply and the allowable levels of such substances. Guidance within the Water Fittings Regulations provides information as to the methods of installation, appropriate levels of backflow protection and aspects of design to ensure a product is correctly installed within a premise.

The appropriateness of the fittings design and manufacture is normally judged against current British or European Standards. One of the means by which the UK Water Regulators ensure that items meet the requirements of the current legislation is by a voluntary testing schemes operated and managed by WRAS or KIWA on behalf of the industry.
