Polymer pipework manufacturer, REHAU, has successfully secured independently tested drinking water approval for its RAUTITAN multi-layer composite pipe (MLCP) system through KIWA UK under its KUKreg4 certification scheme.
All products connected to the UK water supply must comply with Regulation 4 of the Water Supply Regulations. REHAU explained: “Until recently, the most common method of demonstrating compliance was to hold WRAS approval, but more recently, KIWA and NSF have also begun offering independent certification for Regulation 4 compliance.”
RAUTITAN stabil in sizes 16 to 63, RAUTITAN flex in pipe sizes 12 to 63, and the RAUTITAN Smart Link manifold system are now certified by KIWA under its KUKreg4 scheme. The pipe systems are certified to Level +1, with annual surveillance via regular testing and factory audits.
Franz Huelle, Head of Technical at REHAU Building Solutions, said: “We have long championed RAUTITAN as the number one choice for drinking water, with over 800 million metres of pipe sold to date. In securing KUKreg4 approval, we have taken this one step further and re-affirmed the pipework’s position as a trusted solution. This level of assurance allows RAUTITAN to be a true fit-and-forget solution, meaning contractors can safely specify it for projects without having to worry about hygiene or drinking water quality becoming an issue later down the line.”
RAUTITAN’s smooth surfaces reportedly prevent deposits from building up in the pipe, ‘eliminating the risk of microbial contamination from bacteria such as Legionella’, with the pipework certified as ‘germ-free’ by the Fraunhofer Institute. The system’s RX+ fittings are also composed of corrosion-resistant gunmetal rather than lead, ‘negating the risk of leaching’.
Franz Huelle added: “RAUTITAN has long been equipped with a host of features that make it a premier choice for drinking water specification. The reliable jointing system and requirement for no O-rings allows for simple visual inspection when installing, and the MLCP composition is proven to be more hygienic than cooper or steel alternatives.”
