hi, went to a house today and they have had some contractors modifying there house, they are having there supply pipe renewed and i think its very dodgy. they have brought the pipe round to the back of the house but instead of going through footings to inside off house they have brought it up on the outside of the wall and plan on drilling it through about a foot up. i thought this was a no no but they have told they home owner that its aloud as long as they insulate it.
