Water pipes in walls

jimbo_the_jetset

I'm wanting to chase out my bathroom walls to put in the cold water pipe that currently runs surface mounted.

I understand that plaster and cement corrode copper pipe.

The simplest way I can see is to chase the wall out, install the pipework (clipping it securly to oprevent rattles) and fix over a bit of plasterboard and skim over? It will be tiled over anyway so the plaster won't need to be perfect.

I think you can use plastic pipe (either as the water pipe or run the copper pipe through a larger diameter plastic pipe). Can you fit plastic and copper pipes together?

Anyone got any hints/tips? Or experiences?

You can perfectly join both copper and plastic pipes together. Remember to use inserts for this assembly (using straight connectors or 90deg).
For protecting your copper pipe from the cement (plaster will be ok), run a length of heavy gauge plastic, trimmed to fit along the copper. If you do the job before connecting pipe back, you can even wrap plastic strips around the pipe.

Why not cover your copper pipe with a few layers of pvc insulating tape or gaffer tape. This will keep the pipe insulated from the cement / plaster as well as keeping the diameter of the pipe to the minimum, and so reduce the size of the chase?
tape it fix in place and replaster. http://img.moneysavingexpert.com/icons/icon7.gif

Wrapping the existing pipe in tape as above is the best way, as you dont really want to be joining pipes and having the joints buried unless they are copper soldered joints....just my experience
