Low-pressure mixing faucet

Hi,

my girlfriend recently moved and her new apartment is in an old building, there is a boiler/instant water heater available...

What must be considered when installing a low-pressure mixer tap? It must be different from a normal high-pressure fitting, right?

Low-pressure mixing faucet and corresponding armored hoses. Otherwise, I am not aware of anything else. We currently still have it in the kitchen as well.

That's right. Karsten
