    Hi,

    I'd like to put the 22mm flow and return pipes into the wall to keep them out of sight (don't want any ugly boxing in). I can fairly easily chase out about 25mm depth on one wall (its just plasterboard and plaster).

    My question is should I go with plastic or copper pipe? will the plaster crack?

    Many thanks

    I still don't like plastic, but that's personal choice.

    You'll need to go deeper than 25mm. Whether the plaster cracks or not depends on whether you can create a gap between the pipes and the plaster you use to fill the chase. If you can't you will probably get hairline cracks when the pipes expand and contract.

    If it's plasterboard and plaster then is it a stud wall, or is dot'n'dab and there's brick/BB behind it?
