Thank you ' Peter the plumber. ' 15 mm copper is confirmed as my only long-term option. Fernox protection was definately used at installation, and after the new radiator was fitted, as I supplied all parts from my sister's Builder's Merchants Business, and saw the work being done and kept the used fernox containers. I am currently trying the William Wilson brand of system cleaner, which I put in myself, after draining just one radiator+header tank;- 4 weeeks quoted for de-sludging old systems. I am not very hopeful as I have already tried the Fernox brand concentrated desludger, which I injected into that same cold radiator in the kitchen, a month ago. My friendly plumber has a poor opinion of that concentrate. The original choice of plastic was mine entirely, without any comment from my sister or any plumbers;- My team of jobbers just did as they were asked, but later did other systems the same. The plumber who fitted the replacement radiator,and refilled using fresh Fernox, said he would not have used small-bore of any material, just 15 mm copper to and from the radiators, and larger copper elsewhere.
