ᐅ New Water Connection Inside the House for an External Submersible Well Pump

Hello,

I would like to connect an external deep well pump to my house later on and make it frost-proof.
How do you create a new frost-proof water connection in a house where the foundation slab rests on a filled-in basement?
The well pipe would run about 1 meter (3 feet) deep to the house, but how do you then get from the wall into the house and inside the house down to floor level?

I appreciate any advice.
Best regards

Don’t you have an external water connection?

The deep well pump is currently connected to an external water maintenance chamber via a T-piece, but I want to relocate the associated electronics (pressure regulator) inside the house because I experience layered water in the chamber during winter.
Therefore, I am considering a new water connection to the house.
