moving mains water from one room to another

[ambercelery]

hi

I have opened up my kitchen and dining room by removing the partition wall between and am now wanting to swap the kitchen into where the old dining room was.
To do this, I need to get the mains water across into that room (it currently comes into the house underground from the back garden, through the foundations and up into the kitchen).

Rather than dig up all the outside and dig under the foundations etc, am i able to dig a 2-3 inch trench inside the house - running parallel with the house back wall and put new copper pipe in that, to direct the water to the new room ?

You will need to insulate pipe but as long as it don't leak then carry on.

Another thought......why not run it up the wall and through the first floor floorboards to your desired position.
