Ok I am glad someone is speaking to me properly now, thanks:
"It sound slike your pipes are 15mm, the Trevi Boost requires 22mm, so here is what you do, either pass 22mm pipes down from the loft or use special olives inside the 22mm compression fitting to accomodate 22mm pipe"
hum this is a problem-see complex thats what I mean-i presume an olive connects pipes-couldn't I add this to the exposed pipes or do I have to go into the loft and do it?
cheers
