Based on the Bitko Multilayer Pipe, the system is built for safety and reliability, using corrosion-proof components assembly is clean, safe and fast. The smooth inner surface of the Bitko Pipe prevents deposit accumulation and corrosion, leading up to 30% more flowing than metal pipe. Combining the advantages of plastic and metal, the Bitko Multilayer Pipe is ideal for all common hot and cold water installations. Bitko Pipes and Fittings carry the NSF and DVGW certificate for potable water.

A whole system with Bitko five layers in one pipe do it all
With Bitko's five layer composite pipes, an advanced product has been developed that unites the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. This offers product advantages that are second to none:

Form stable; the bends stay in place, making the system quick to install while using fewer fittings.
Linear expansion rates closer to copper than other pure plastics pipes.
The aluminium core is absolutely diffusion tight.

And a lot more of advantages! Please see the full technical manual for more.
