What type of fitting do I use to adapt from a poly rising main to copper?
Currently the main goes straight to 15mm copper using some sort of brass
fitting but I want to change this to 22mm, unfortunately it's in a corner
and near the floor so it's going to be a b*gger of a job.

MDPE usually uses plastic push fit fittings.

You should find couplings to connect the plastic to 22mm pipe, try your
local plumbers merchants

Where's DIMM, has he broken his hacksaw blade or what?
