All new house builds are done in plastic nowadays arent they??
Not all new builds.
I prefer 22mm copper pipework with 10mm manifolds, it lasts longer and looks better IMHO but I don't mind using plastic if that's what the cust prefers due to cost of material or less labour cost, my only condition Is they have to take a magnaclean or something similar. I don't like ch in plastic with no corrosion protection. Alot of new estates round our way fitted plastic with no protection and they notorious now for choked diverter valves/pumps knackered trvs and cold spot rads

I understand why this seems unusual-plastic pipe/corrosion
the only reason I can give is they've not used barrier plastic, it's the only reason I can think of having seen so many of these systems, they are mostly potterton puma boilers and the wax capsules always fail eventually.
Anyone else who more clued up on the exact chemical reactions etc with the system with water/oxygen/metals/plastic may be able to explain it better
all I know is if the ch pipework is fitted in plastic (in the area I work) then the ch water is gona be as black tar, I just take it as given now. Magna protection prevents this
As I understand it if its Non Barrier it will allow oxygen through the pipe wall which is then entrained as free oxygen in the water . Oxygen + iron (rads) = the dreaded !!
Lots of systems our way blocked solid !! Barrier pipe no problems .
And from our experience inhibitor made no difference
Would that have been Acorn pipe ? We had awful trouble with that , water like oil !
Our water is soft , no limescale what is yours ?
