Hi all. Question for the plumbers or those with the know how.
I am in the process of building an ensuite in our new bedroom, the heated towel rail, "Can i use 15mm plastic pipe direct to the flow/return valves" as opposed the the traditional copper pipe.
The reason for using plastic is, all the pipework will be boxed in then tiled, i would like it to be joint free in that area untill the pipework exits into a part of the roof that is maintainable for the rest of the pipes.
Thanks in advance.
