I was considering running a spare pipe system from boundary to kitchen (poking as far through through the wall as possible) and then "terminating" both sides in future but then its an added issue breaking the concrete out the front of the house to get through near the boundary stopcock...
I think ill see if i can cut a small section of the kitchen floor to where the straight run would end and reconsider my options from there when i see whats up
Unfortunately the joint is like a meter from the wall so i wouldn't be able to reach through. I was looking up plastic vs copper and as much as the flexibility half the cost wins, I've found some research articles about micro plastics with plastic piping potentially being a long term issue. Fortunately its a straight run so i can just poke a pipe through. I think ill see if i can cut a small section of kitchen flooring and see if i can find the end of the straight section and go from there. Might save me a lot of work
