I wouldn't go up into the loft and then back down again unless you really have to. The feed to my ensuite (which I didn't install!) does this - and gives up if there's a heavy demand anywhere else in the house.
You haven't said what you're doing with the waste pipes. I would have thought that they were a bigger problem than the water pipes.
