Chased pipes into wall.

[MC78]

What is the minimum depth of plaster required to cover central heating pipes chased into a wall, my plumber has left about 1mm of space from the surface of pipes to the surface of the plaster, I'm doing the filling but I'm not an expert and 1mm don't seem enough to me. Can someone please advise me.

Defo not enough depth! My pipes had enough room to cover with pieces of 9mm plasterboard, bonding and then skimmed over.

Having just spent 1 1/2 days locating and replacing leaking pipes buried in a plastered wall and also into sub-floor screed, my vote is deffo for sleeving or ducting. The copper pipes I dug out were corroded to hell. Also agree, 1 or 2mm of gypsum plaster will crack up.

Just do really tidy copper pipework on the surface- think Pompidou.

Yes indeed, building ducting and then plastering over it seems like an effort to me.

My perspective if I'm burying pipework then it has to be joint free, like wet under floor heating.

I used to put pipes in walls on new builds and that was plastic but there was always a drama when the kitchen fitters went in. Then there would be joints in walls ripe for failure in about 10 years.

There was no time to build ducts, just metallic tape so they are picked up with a stud finder.

I suppose if you have the money and the time you could build purpose made ducts that can be accessed, much like the ones you find in modern flats.
