What advantages does a WRAS Approval give?

By Beta Valve on Thu 18 July 2019 in WRAS/Certifications

Any water fitting, which when installed, will carry or receive 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’. 

A WRAS approval is an easy way to demonstrate compliance for a material or water fitting, other approval schemes are available.

There are two types of WRAS approval, the WRAS product approval and the WRAS material approval.


A WRAS Product Approval for complete products (valves, washing machines etc.) ensures that, provided the product is installed or used in accordance with any conditions placed on the approval, your customers (or their customers) are installing a fitting that complies with the requirements of the Water Supply (Water Fittings) Regulations and Byelaws and they have therefore met their legal requirements.


A WRAS Material Approval for non-metallic materials and components, such as plastic parts, rubber seals and ‘O’ rings, involves testing only for their effects on water quality. This type of approval demonstrates that the non-metallic material does not itself contaminate the water and therefore satisfies this particular requirement of Regulations and Byelaws.
