With more and more Legionella and Pseudomonas tap and shower filters on the market, it is vital to understand the importance of using certified products when it comes to the Medical and Life Science industries.
Below is the documentation explaining where the information comes from and the framework of each certification.
So, what is a WRAS approval?
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’.
For all buildings, it is stated in chapter 2.33 of the second part of the HSG 274 document: “Materials used in building water systems must be compatible with the physical and chemical characteristics of water supplied to the building to reduce corrosion or prevent excessive scale formation of system pipework and components. Domestic water systems must not use materials that support microbial growth, such as those containing natural rubber, hemp, linseed oil-based jointing compounds and fibre washers. Similarly, any synthetic materials used should not adversely affect water quality by supporting microbial growth. Water fittings and components should be used that comply with the Water Regulations Advisory Scheme (WRAS) approval scheme 27 which lists products that have been tested and comply with BS 6920.”
More specifically for hospitals, HTM04-01: Safe water in healthcare premises Part B: Operational management states in paragraph 0.24 accentuates the matter: “As well as complying with the recommendations outlined in this document, the design and installation of the hot and cold water services, new or extended, in any healthcare premises should also comply with:
- the Water Supply (Water Fittings) Regulations 1999;
- Defra’s guidance to the Water Supply (Water Fittings) Regulations;
- recommendations of the water suppliers in the Water Regulations Advisory Scheme’s (WRAS) ‘Water Regulations Guide’, and
- any other requirements of the local water undertaker. recommendations of the water suppliers in the Water Regulations Advisory Scheme’s (WRAS) Water regulations guide.”
