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)

As I said, you’re not allowed to do that, and no one can help you with it.

Is a social worker allowed to change the tires on their car?
Or is that only permitted for a trained automotive technician?
A moving vehicle poses a significantly higher risk to the public.

He is allowed to change his own wheels.
However, I don’t see the connection between that and the other matter, or was that simply a question?

By the way, there is the "Regulation on General Conditions for Water Supply," which clearly states this. I am not aware of any regulation regarding the handling of winter tires (winter tyres).

Sorry, I am not a specialist. Where exactly?

This applies to the public supply line...

No, §12 applies to private homes.
- Paragraph 2 specifies who is allowed to make changes.

Strictly speaking, you are not even allowed to replace a faucet – but you shouldn’t overdo the strictness either.
