Burying pipes in walls

[almonkeyfinger]

Sorry if this is the wrong forum...

I have two microbore pipes running down the wall in the hallway from the ceiling to the radiator. As i'm redecorating i was wondering if it is ok to knock a channel into the (external) wall, and put the pipework into some conduit into the chanel, then plaster over ? My only concern would be if the heat of the pipes would cause the plaster to split but they are microbore and i would wrap them in some lagging.

What are peoples thoughts ?
Thanks

Use of conduit is good. Without checking the Water Regs I'm not sure, but it might even be mandatory (although not retrospectively so).

If the pipes are copper then denzo tape will protect the copper from the plaster. You might consider lagging, but anything compressible will serve to make the plaster vulnerable to cracking by not having a firm base.

If you're able to disconnect one end of the pipework (draining the relevant part of the system first of course), then you could feed 'proper' conduit over the pipework, which deals with both problems
