Any water fitting or water-using appliance connected to the mains water supply must comply with the Water Fittings Regulations (or Byelaws in Scotland). This ensures the appliance does not waste or contaminate the drinking water supply. In order to demonstrate compliance, a number of companies exist (typically WRAS or Kiwa) who test appliances to ensure they conform with these regulations.
