Copper Pipe damage.

[BlackOmega]

Hi all,
Can anyone tell me if a mortar mix will damage or corrode or damage Copper pipe.
Thanks.

It will affect it eventually so you should protect it in a duct or wrap denso tape around it.

I have known people slide (unslit) climaflex pipe insulation over the pipe before backfilling. It is made of closed-cell polythene so presumably impervious (as well as allowing expansion and providing thermal insulation)

has been known. but not allowed under water regs.

didn't know that (not a plumber). looked like a good idea to me.

Complete tripe.

try reading the water regs then.
which proves you ain't got.

Can you give a quote in the regs where it says you cannot sheath buried copper pipe in closed-cell polythene insulation ?.

 

[hi-spec plumbing heating]

yes thanks.

 

[Balenza]

yes thanks.

Then post it.

Whats the matter ?. Can't quite find the relevant section that gives the appropiate information relating to what JD posted.
No surprise there.

i don't need to find it look on page 3.21
oh no you don't have a water regs cert so you won't have a book.

Says nothing about restrictions on using closed cell polythene insulation on copper pipework in this section .
It talks about concealed fitting and the latter part of R7.3 states "Where both cold and hot water pipes are located in this type of duct the pipes should be separately insulated over their full length".
I would have thought closed cell polythene fulfilled this category.
