Hello,
Our regulations include the following statement:
When you look at the DIN/VDI standards regarding branch lines, the external water tap must be connected directly to a ring main (otherwise there is a risk of contamination). Consequently, a water meter could theoretically not be installed in the line as suggested.
Here is my idea: I will install the water meter (frost-proof version) on the frost-proof pipe section coming from the wall (which actually serves as the external water tap) and attach another water tap behind the meter, declaring this as the external water tap. The whole setup is enclosed in a large wooden box.
Do you think this could work? According to the authorities, no one really wants to inspect it; I just need to report the meter reading every year. The water association, which reads the main meter, has nothing to do with the authorities.
Our regulations include the following statement:
The sub-meter must be permanently installed in the water line or pipe leading to the external water tap.

That’s not the point. The branch line remains inactive for 8 months per year. The water inside accumulates microbes over time, which then migrate back into the main pipe and are drawn off as usual.
The relevant regulations state:
DIN EN 806-2, 18.3
To prevent stagnation, the installation must be designed so that under normal operating conditions there is regular renewal of the drinking water.
DIN EN 806-4, 4.8
Fixtures and pipes must be arranged to reduce stagnation.
One could of course speculate whether a water meter plus a connection terminal is acceptable. What is absolutely clear, however, is that the meter shortens the branch line after the tap and thus supports the requirement stated in the second section.
Our plumber argued exactly that way when we wanted a connection area inside the house. It was definitely NOT overlooked.

And you don’t need it for 8 months? Interesting. Why do the work at all then? And what do you need the faucet for?

When reading about this topic on bosy and similar sources, you find that stagnation is said to occur after as little as four hours. This applies here to every single faucet multiple times a day.
One then wonders whether the issue of bacterial growth is actually relevant or just a marketing tactic.
