Hi all. This is mainly preference I know but when running hot and cold pipes from kitchen sink to a bathroom in the next room (ground floor) would you go straight up in to the ceiling and go across. Reason I ask, I'm on a council contract at the mo and next job is complete first fix from mains in kitchen. It's bang in the middle of kitchen sink wall and I don't know whether to go low level to the corner then go into the ceiling or straight up and go service high level to the bathroom next room. ??? Daft post I know.
