Are the materials used in my drinking water installation safe to use?

The materials used in alpex multilayer composite pipe systems meet highest requirements for drinking water installations and have been certified and approved according to DVGW. Both the alpex composite pipe designs with internally cross-linked PE-X materials and a butt-welded aluminium core (PE-X / AL / PE) as well as the corresponding fittings made of PPSU or dezincification-resistant brass for threads are physiologically safe and of food quality, i.e. the material has no adverse effects on the human body. Hygiene and microbiological testing is an integral part of the DVGW type approval certificate and is particularly stringent with plastic pipe systems. The materials applied comply with the currently valid list of approved materials of the German Environment Agency (UBA) and the Drinking Water Ordinance.
