Kiwa – The myth of WRAS- Water Regulation 4 and KUKreg4 explained
onathan Price, Business Development Manager at Kiwa Watertec, explains what Water Regulations 4 and KUKreg4 means
J
The Water Supply (Water Fitting) Regulations are important for public health, safeguarding water supplies, and promoting the efficient use of water within premises across the UK. All water installations in the UK need to comply. In respect of water fittings and their requirements, reference should be made to Regulation 4. Regulation 4(1) states that ‘every water fitting should be of an appropriate quality or standard and be suitable for the situation in which it
is used’ and regulation 4(2) provides options to demonstrate compliance.
It’s important to have certification in place and demonstrate compliance as this will satisfy water authorities, specifiers and contractors that the product has undertaken the required testing, and meets the necessary design requirements for its use. Also using a certification mark, such as KUKreg4, also gives a product a competitive advantage over alternatives that do not have any certification or compliance.
KUKreg4 is a robust method for demonstrating compliance with Water Regulation 4 as the testing is undertaken in an ISO 17025-accredited laboratory and complies with ISO 17065 product certification. During the process of certification, products undertake rigorous testing, and the certification decisions are made by people who have many years’ experience in the industry. Historically, WRAS has been the most well- known certification mark among contractors, specifiers, and water authorities but with the industry now using the correct terminology that products must be ‘Regulation 4 compliant’, this is undoubtedly increasing the visibility of KUKreg4 in the industry. A key point to remember WRAS is not the legal requirement, Water Regulation 4 is and KUKreg4 is a way of demonstrating this.
A key advantage of the KUKreg4 option is that certification decisions are made within Kiwa, so there are no cut-off dates for products to be granted certification. Also, with Kiwa being recognised across Europe, there are opportunities within the certification process to save manufacturers’ time and money on testing because for certain product groups, the testing and certification process can be cross-referenced. Kiwa also offer two levels of certification level 3 and level 1+, the 1+ is a continuous certification rather the 5 year renewal.
Key take away……. WRAS is not the legal
requirement, KUKreg4 is equivalent in the way of compliance
