What flows through your tap deserves the highest standards
When it comes to drinking water, the quality of the piping system matters just as much as the water itself. Across Europe, copper tubes used in potable water systems are manufactured according to strict standards designed to ensure safety, reliability, and long term performance.
EN 1057, the European standard for seamless round copper tubes used in drinking water, gas, and heating systems, defines key requirements for dimensions, mechanical properties, and product quality. Together with the EU Drinking Water Directive, these standards help ensure that materials used in contact with drinking water meet high hygiene and performance expectations.
Thanks to its durability, corrosion resistance, and long service life, copper continues to support safe and reliable water distribution in buildings across Europe.
Behind every tap, copper helps deliver confidence in water quality day after day.
