Crossing over a 22mm and a 15mm pipe

[BarnabyT]

I need to cross a 15mm pipe over 2 parallel and vertical pipes..... one of them is 22mm, the other is 15mm and they are 15mm apart. Will a normal 15mm cross over do the job, or is there a better way?

How are they going to cross if they're parallel? Or are we talking a small design fail here
EDIT Ah, just realised my mistake- no you'd need a pair of half crossovers or get creative with the tube bender
EDIT 2- Just looked again at catalogue- my bad, half crossovers won't do it. 4 x 45° elbows then or pipe bender

Photo would help massively, 15mm won’t clear a 22mm pipe. Also you should consider undue warming if the pipes are carrying cold water.
