Mono Bsin Mixer

[mark456]

I've got to the stage on my project where I need to fit the mono basin mixer. My problem is I've fitted the flexi tales on to the feed pipes with isolation valves(i've left small holes to access the valves) but I've boarded over and plastered the wall. Am I going to have to break into the wall, remove the compression ends and fit to the basin mixer first? or can I tighten the nuts on the other end and fit to the basin mixer?

Someone please help

As you can probably appreciate now, shutting the iso. valves will serve little purpose if you can't actually get to the plumbing to carry out any work, or even assemble it in the first place.
