What does WRAS Stand for?
WRAS stands for: The Water Regulations Advisory Scheme (WRAS for short). It is a conformance mark that demonstrates that an item or product complies with the high standards set out by water regulations 1999 in the United Kingdom.
WRAS is the standard against waste, misuse, undue consumption or contamination of the water supply & must be 'of an appropriate quality & standard. WRAS rules apply to any water fitting that once installed, will carry water from the public mains water supply.
The two main variants include:
WRAS Product Approval: Whole products such as valves, boilers and showers undergo mechanical & water quality testing. This type of approval demonstrates full compliance, provided the fitting is installed according to any conditions given with the approval.
WRAS Material Approval: Non-metallic materials & components such as rubber sheet material, ‘O’ rings & spacers undergo testing only for their effects on water quality. This type of approval demonstrates that the component does not contaminate the water similarly.
