ᐅ Proper Piping System & Appropriate Pipe Diameters for Plumbing?

Hello everyone,
For our renovation project, I plan to completely redo all the (pipe) installations. I have two questions in advance:
- For aluminum composite pipes, which system is better: crimping or compression fittings?
- What diameters are generally used for radiators and domestic hot water?
The layout will be:
Basement: Heating system in the basement, with only one cold water connection (washing machine separate, supplied with rainwater)
Ground floor: Kitchen with one sink (hot + cold) + dishwasher,
Bathroom with shower + washbasin (toilet is separate, supplied with rainwater),
5 radiators for 5 rooms, total 90m² (970 ft²)
Attic/Top floor: Bathroom with shower + washbasin (toilet is separate, supplied with rainwater),
4 radiators for 4 rooms, total 65m² (700 ft²)

*By “installing the faucet,” I meant exactly that, as I mentioned earlier.
Completely redoing the plumbing in a house definitely counts as a major modification.
But this discussion isn’t about legal issues; it’s about the fact that this simply isn’t a DIY job and shouldn’t be treated as one. In my opinion, the original poster (OP) should not be encouraged to attempt this under any circumstances.
Two scenarios from my experience:
Case 1) The plumbing installation was done entirely by a professional company. Unfortunately, a fitting was not properly crimped. About a year after moving in, water started creeping up the walls and leaking through the seams of the floor-to-ceiling windows.
Result: The ground floor had to be completely gutted and renovated. The cost was nearly 100,000 euros (about $100,000), all covered by the installer’s insurance.
In the OP’s case, they would be left footing the bill and facing serious financial trouble.
Case 2) The plumbing was entirely done by a skilled tradesperson who is also talented at hands-on work. When finished, the water utility refused to connect the water meter until the pipes were inspected and approved by a certified company. It took him three months to find someone willing to do the inspection—and what he ended up paying would have been enough to have the entire job done professionally in the first place.

So, I can only repeat my well-intentioned advice: have a professional company do the work.

You are absolutely right. More and more municipalities/utilities require installations to be carried out by a certified company.
Very few people want to deal with tearing out screed or having rainwater mix with drinking water.
If you are not familiar with a particular trade, it is best to seek professional help.

If a plumber came to you tomorrow and said he wants to start teaching 10th grade German and history next week and quickly needs to know what material is currently taught and how to teach it – what would you say? "Sorry, but I am a social worker, not a teacher."

Case 2) The installation was completely done by a skilled craftsman who is also good at manual work. When he finished, the water utility refused to install the water meter until the pipes were inspected and approved by a certified company. It took him three months to find someone willing to do this – with what he had to pay for it, he could have had it done professionally from the start.Well, that sounds like a workable alternative – except that it’s best to arrange a suitable company in advance to discuss conditions and requirements, and then have them inspect and approve the installation after it is completed.
