what connection for hidden shower valve?

[chrisz]

I've got this hidden valve:

It has 3 3/4 inch feeds - one hot, one cold, then then one that I am running to a fixed shower rose.

what type of fitment do I need to connect these to copper pipe? (I guess 15mm). Links would be great.

Many thanks
Chris

yeah, I will, was just trying to save the trip and ask an expert on here.

after a bit of hunting around I have found a male 3/4 inch compression coupling. I have only found ones that connect to 22mm tube though. Is it the best solution to run 22mm tube straight to the shower valve or find a 3/4 inch to 15mm coupling which I haven't been able to so far, or should I use a the 22mm coupling, then reduce it to 15mm.

help.... please!

plumbcentre do 3/4" to 15mm male iron.
or do a 3/4" to 22mm male iron and then use a 22mm / 15mm reducer.
