Due to the current situation, my plumbing company unfortunately canceled, so I have to handle the water installation myself in my newly purchased older house. I have chosen multilayer composite pipes with screw fittings from the company CONNECT.
Now I am uncertain about the connection to the fresh water (cold). Can someone tell me which adapter I need to connect a 16 mm (5/8 inch) multilayer pipe to the water supply?
The galvanized steel pipe visible in the second photo runs about 8 meters (26 feet) along the basement ceiling and then splits at a T-joint into smaller-diameter copper pipes. Should this section possibly also be sized with a larger diameter?
The water supply basically only serves the ground floor; there is only a toilet with a washbasin on the first floor, so a lower water pressure there would not be a big issue.
I have attached the photo. The brass (?) part says "RN22 DVGW Kiwa."
If any information is missing to solve this problem, please just ask, and I will provide whatever is needed – since I am “only” a DIYer, I wouldn’t be surprised if this thread has technical gaps.
I would be very, very grateful if someone could help me!
Best regards!

The "few" extra euros compared to the original quote are well spent.
I wouldn’t risk water damage (sooner or later) in the new old building.

Hello
The total flow rate is about 0.84 l/s (1.8 gal/min), and the peak flow rate should be around 0.45 l/s (0.95 gal/min).
I don’t have the table for rough calculations at hand right now.
So, a 22mm (7/8 inch) copper pipe needs to be installed. With composite pipe, you’d be looking at a 25 or 26mm (1 inch) pipe.
A 16mm (5/8 inch) pipe is definitely not suitable here!!
