Hello,
our outdoor water tap is connected to a ½ inch wall penetration and behind it there is a Grundfos MQ 3-45, which draws water from a well outside the house. Since the ½ inch is of course not ideal, I am considering upgrading the wall penetration from ½ to ¾ inch. However, it is not clear to me how the outdoor water tap was attached and how I can replace it and the pipe of the wall penetration without damaging the exterior wall. It is definitely a wooden stud wall with Fermacell, polystyrene insulation, and silicone resin plaster.
Could you possibly give me a tip on how I, as a layman, can implement this without damaging the exterior wall and especially the visible plaster?
Here are a few pictures of the situation.

Regards Jochen
