NSF REG4 Readiness Tool
The NSF REG4 certification scheme for the UK market allows plumbing products and materials that are in contact with drinking water to demonstrate compliance with the UK Water Supply (Water Fittings) Regulations 1999. We developed this certification as a streamlined way for plumbing product manufacturers and materials suppliers to conform to UK regulations and gain timely access to the UK market.
The certification scope includes mechanical products in contact with drinking water, such as appliances, valves, backflow-prevention devices, taps, mixers, shower heads, pipes and fittings, tanks, cisterns, water meters, and many others. It also covers nonmetallic products, such as plastics, rubbers, coatings, cement, resins and sealants.
We created the NSF REG4 Readiness Tool to give you insight into your potential readiness to enter this certification process with NSF.
