In England and Wales the Water Supply (Water Fittings) Regulations 1999 (‘the regulations’) regulate how water systems are designed, installed and operated. Regulator Specifications that provide detailed performance, verification and in some cases installation requirements, can also be approved.
Defra and Welsh Government are seeking your views on proposed amendments to the WC Suite Performance Specification, the Specification on the Prevention of Backflow and associated specifications commonly referred to as Test Code Sheets. The changes are to address incidents of backflow from WC cisterns whilst reflecting innovations in the design of WC suites.
