Hi,

Can anyone please help me with the following ?

1) Can bare copper pipe be buried (viz. with cement & plaster rendering
afterwards) in a brick partition wall ? If not, what protection measures
should be taken/are available ?

2) Same conditions. Can heavy duty plastic (1/2 inch) be used ? What
would be it`s estimated lifespan ?

3) I realise mixing galvanised iron and copper pipe is normally a no-no
If there are circumstances that make this imperative, what measures (if
any) can be taken to reduce corrosion effects ?

4) Can builders foam be used as an effective pipe sealer/protector when
installing in a wall ?

You may gather from the above that I`m stuck with having to renew
H&C supplies originally laid in walls and floors.

TIA.
